Identification Of Soil Erosion Prone Zones Using Geomatics Technology In Part...IJERA Editor
Soil erosion is the removal and subsequent loss of soil by the action of water, ice, wind and gravity. Soil erosion is a process that occurs naturally at a slow rate. The average natural geologic rate of soil erosion is approximately 0.2 tons per acre per year. Erosion is the process were by the earth or rock is loosened or dissolved and removed from any part of earth‟s surface. Geological erosion is the rate at which the catchment or land would normally be eroded without any disturbance by human activity. If man alters the natural system by means of various land use practices that is caused accelerated erosion. The present study area is covering Parts of North Arcot The area is lies between E78°30'-E78°45' lattitudes N12°15'-N12°30„. The total aerial extent of the study area is 720 sq.km. It falls in the survey of India Toposheet 58 L11 on 1:50,000 scale. The IRS – 1D satellite imagery data were subjected to different types of image enhancement techniques and soil erosion areas were mapped out and GIS databases were generated showing the soil erosion areas using Arc Map 9.1 version. GIS overlay function was executed between soil erosion prone areas and the various controlling variables and the area has been fragmented into a number of polygons of land segments depending upon the controlling variables. Finally, the remedial measures were suggested for each land segment according to the controlling variables.
1) Species richness and abundance of seeds and seedlings of woody, ocean-dispersed plants were higher along natural coastlines compared to armored shorelines. However, species richness and abundance of herbaceous plants were higher along armored shorelines.
2) Both coastal types shared some similarities in plant composition, but each housed different types of plants. Higher numbers of seeds and seedlings from native coastal woody plants along natural coastlines suggest armored shorelines pose challenges for recruitment and establishment of these species.
3) No relationship was found between the abundance of land crab holes and the abundance of seedlings. Additionally, the abundance of the most common plant species, Hibiscus tiliace

Environmental systems are complex arrangements of interacting biological, physical, chemical, social and economic components within the Earth's environment. They can include systems like the atmosphere, oceans, and populations of plants and animals. Models are used to study environmental systems and can take various forms from simple empirical models to complex process-based models. Environmental systems generally have four main features - they involve complex nonlinear interactions; their characteristics vary greatly over spatial and temporal scales; these scales are often incompatible between components; and many processes are unobservable. The key types of environmental systems are hydrological, ecological and climatic systems.

This document summarizes a study of coastal zone management in Cuddalore District, Tamil Nadu, India using remote sensing and GIS techniques. The study analyzed shoreline changes between 1971 and 2012. The results showed alternating periods of erosion and accretion across the study area. The northern region experienced land loss from 1971-1991 followed by erosion after 1991. The central region accreted from 1971-1991 then eroded after 1991. The southern region was dominated by erosion, except after the 2004 tsunami when deposition occurred. Overall, erosion activities were higher than accretion across the study area over the 41-year period.
The Impact of the Utilization of Riparian Area for Settlements (Case Study of...Suwandi, Dr. SE.,MSi
The limitedness of area and plot of land in Jayapura City which are allocated for settlements has become a problem in Jayapura city. Population growth and high-rate of urbanization are impacted on the utilization of land which is not in accordance with its allocation. The modification of riparian area on the right and left sides of the river for settlements has reduced the function of the river, because in addition to river conservation, river has a double role as the securer of water source and as the protector of its surrounding area. Therefore, riparian area becomes more important to be considered. The riparian area in settlement area is assumed to be adequate for a 10-15 meters inspection road to be built on. The real condition of the rivers in North Jayapura District of Jayapura City, compared to the criteria of riparian area for settlement area, has not been inappropriate. The river’s function as the protector of its surrounding area has gone astray. If there is someday a flood, the impact may cause material damage or even life victims.

'..Until recently sand was extracted in land quarries and riverbeds; however, these inland resources have nearly been depleted so that extraction has shifted to marine and coastal aggregates mining.'
Sand from deserts cannot be used for most purposes, as wind erosion over time forms round grains that do not bind well [4]. For most industrial uses, edged sand grains with a rough surface are needed, which stick together naturally. Desert sands, however, are usually fine- grained and of low shear strength –it does not even suit as material for the creation of artificial islands. Dubai, for example, used up all its suitable marine sand supplies for an artificial set of sand islands and, after these were exhausted, now has to import sand from Australia for continuing its building madness.
Most of the sand is by now extracted from the ocean floor – globally thousands of large boats are sucking up huge quantities of sand from the ocean floor in coastal areas like vacuum cleaners. As a result of currents, gravitation and movements of the waves, the gaps which were created by sand extraction are then filled by sand sliding in from surrounding areas and beaches. Due to this vicious cycle in Miami each year beaches have to be replenished with dredged-up sand to further provide tourists with its famous beaches.
In some extreme cases, the mining of marine aggregates has even changed international boundaries, such as through the disappearance of entire islands in Indonesia – since 2005 at least 24 small islands have disappeared as a result of erosion caused by illegal sand mining. Most of this sand is going to Singapore, which has expanded its surface area by 22% since the 1960s [5]. In response to this potentially heavy environmental toll many neighboring countries (Indonesia, Malaysia and Vietnam) have now banned exports of sand to Singapore, but this has only shifted the problem to countries such as Cambodia.
The conflicts caused by sand mining were for the first time brought to the attention of the general public through the documentary Sand Wars. Among many other outreach victories, the documentary inspired the United Nations Environment Programme (UNEP) to publish a Global Environmental Alert in March 2014 titled “Sand, rarer than one thinks”. In it, the authors state that “Formed by erosive processes over thousands of years, they [sand and gravel] are now being extracted at a rate far greater than their renewal”.
Coastal biodiversity is under threat from human activities like habitat destruction, pollution, overfishing, and climate change. The document discusses how coastal ecosystems like mangroves and coral reefs have high biodiversity but are being degraded. Bangladesh has many endangered coastal and marine species as well as economically important fisheries that are declining due to threats. Initiatives are underway in Bangladesh to better understand and protect coastal biodiversity through community-based management, conservation programs, and integrated policy efforts.
The document discusses various coastal economic resources in Bangladesh, including heavy mineral deposits found along beaches, offshore petroleum exploration in the Bay of Bengal, marine fisheries resources, agriculture in coastal regions, salt production, forestry including mangrove forests, and tourism attractions along the coast. Seventeen placer deposits of heavy minerals have been found along beaches, while offshore petroleum exploration has identified gas reserves but continued challenges. Coastal economic activities also include marine fisheries, agriculture, salt production, forestry, and developing tourism.

effect of mining activities on vegetation composition and nutrient status of ...IJEAB
Mining is essential in the economic development plan of any country endowed with mineral resources. This is due to both internal and external economic benefits that are made available to countries that are involved in the extraction of mineral resources. Internally, there is creation of employment and revenue generation among others while externally; a substantial foreign exchange is available to such countries. However, looking at the socio-economic importance of the industry, most countries lose sight of the ensuing effect that might accrue to an area as a result of mining activities. This study sought to provide an empirical data to ascertain whether or not mining activities has affected tree diversity of the area in general and on vegetation and soil nutrients in particular. In the study diversity indices (Shannon, margalef and Pielou’s evenness) all indicated higher values for adjacent site 5 km away from the factory. Soil health indicators investigated revealed significant differences except Potassium, with adjacent site having higher mean values. This study has indicated that tree diversity was higher in the adjacent site and also that soil 5 km away from the factory was healthier than soil within factory site. Construction of shield over factory site is suggested.

This document summarizes a study on the hydrogeochemistry and environmental implications of the Periyar River in southern Western Ghats, India after severe flooding in 2018. The study analyzed water and soil samples from different areas in the Periyar River basin to understand changes caused by the flood. Water samples were tested for various chemical parameters and compared to WHO and BIS standards. Soil samples were analyzed to determine Loss on Ignition (LOI) and composition through X-Ray Fluorescence (XRF). The results provide insight into the current water quality and soil composition/properties in the river basin following major flooding.
This document discusses the projected impacts of sea level rise on coastal areas in the Caribbean. It finds that a 1-2 meter rise in sea levels would displace over 100,000 people in CARICOM nations and cause the loss of 1300 sq km of land. Critical infrastructure like roads and ports would be damaged. Mangrove forests and ecosystems would be destroyed, eliminating their services. The tourism-dependent economy would see losses of 14.8% of GDP and 12.9% of jobs. Adaptation strategies discussed include ecosystem-based approaches, managed retreat from coastal areas, and developing insurance programs.
The document discusses integrating an ecological approach into watershed management. It explains that the current approach focuses on engineering structures and soil conservation, while an ecological approach understands watersheds as mosaics of land features with associated vegetation. It recommends surveying watersheds, streams, and vegetation to design restoration measures that maintain natural processes and services like water purification and habitat provision. Forest cover designs should associate different land features with suitable native plant species to support physical and biological functions across the landscape.

Marine Fertilization and Carbon SequestrationIslam Md Jakiul
This case study examines the effects of bottom trawling on deep ocean floors. It finds that bottom trawling directly impacts fish populations and seabed communities by modifying physical properties of sediments, chemical exchanges, and sediment fluxes. Through repeated trawling, the morphology of continental slopes is gradually altered as the seafloor becomes smoother over time. Trawling also reduces habitat heterogeneity and complexity, potentially affecting biodiversity. Large sediment volumes can be redistributed downslope through trawling activities, comparable to effects of forest clear-cutting on land. Tight regulations are needed to minimize impacts of deep sea mining and protect unique hydrothermal vent ecosystems and their biodiversity. Natural iron fertilization can also effectively sequester carbon in
Integrated coastal zone management md. yousuf gaziMd. Yousuf Gazi
Bangladesh has over 734 km of coastline along the Bay of Bengal with a population of around 50 million people living in the coastal zone. The coastline is difficult with many rivers and is affected by natural hazards like cyclones. The coastal zone is classified into interior and exterior coasts and three regions: eastern, central, and western. Integrated coastal zone management (ICZM) aims to balance environmental, economic, and social concerns through a coordinated management process. ICZM in Bangladesh focuses on managing coastal resources and people sustainably while addressing issues like population growth, infrastructure needs, and environmental challenges.

This document assesses the vulnerability of the coastal aquifer in the north coast of Mombasa, Kenya to seawater intrusion. It uses the GALDIT index overlay method with GIS to analyze six factors that influence seawater intrusion: groundwater occurrence, aquifer hydraulic conductivity, groundwater depth above sea level, distance from shore, existing status of seawater intrusion, and aquifer thickness. Vulnerability maps were created for the pre-rainy and peak rainy seasons. The results showed an increase in low vulnerability areas and slight increase in high vulnerability areas between seasons. The study provides insights to effectively manage groundwater resources in the area.
IMPACT OF CLIMATE CHANGE ON COASTAL COMMUNITIES OF INDIA (EASTERN COAST)IRJET Journal
The document discusses the impacts of climate change on coastal communities in Eastern India. It finds that the Eastern coast, including regions in West Bengal, Tamil Nadu, and Puducherry, faces significant vulnerabilities due to rising sea levels, increased extreme weather events, and disruptions to agriculture and fisheries from climate change. Coastal communities experience threats to livelihoods, food security, and infrastructure from rising seas, coastal erosion, changes in ecosystems, and variability in rainfall patterns. The agriculture and fishing industries that many coastal residents rely on are especially impacted. West Bengal in particular faces severe risks from cyclones and flooding along with rising sea surface temperatures. Urgent action is needed to develop strategies to build resilience against these climate change effects

This document discusses the projected impacts of sea level rise on coastal areas in the Caribbean. It finds that a 1-2 meter rise in sea levels would displace over 100,000 people in CARICOM nations and cause the loss of 1300 sq km of land. Critical infrastructure like roads and ports would be damaged. Mangrove forests and ecosystems would be destroyed, eliminating their services. The tourism-dependent economy would see losses of 14.8% of GDP and 12.9% of jobs. Adaptation strategies discussed include ecosystem-based approaches, managed retreat from coastal areas, and developing insurance programs.
The document discusses integrating an ecological approach into watershed management. It explains that the current approach focuses on engineering structures and soil conservation, while an ecological approach understands watersheds as mosaics of land features with associated vegetation. It recommends surveying watersheds, streams, and vegetation to design restoration measures that maintain natural processes and services like water purification and habitat provision. Forest cover designs should associate different land features with suitable native plant species to support physical and biological functions across the landscape.

Marine Fertilization and Carbon SequestrationIslam Md Jakiul
This case study examines the effects of bottom trawling on deep ocean floors. It finds that bottom trawling directly impacts fish populations and seabed communities by modifying physical properties of sediments, chemical exchanges, and sediment fluxes. Through repeated trawling, the morphology of continental slopes is gradually altered as the seafloor becomes smoother over time. Trawling also reduces habitat heterogeneity and complexity, potentially affecting biodiversity. Large sediment volumes can be redistributed downslope through trawling activities, comparable to effects of forest clear-cutting on land. Tight regulations are needed to minimize impacts of deep sea mining and protect unique hydrothermal vent ecosystems and their biodiversity. Natural iron fertilization can also effectively sequester carbon in

Status of seagrass ecosystem in Kauswagan, Lanao Del Norte and Laguindingan, ...Innspub Net
The study was conducted to determine the present status of seagrass resources of Laguindingan, Misamis Oriental and Kauswagan, Lanao del Norte and compared this through time with secondary data. It employed the transect-quadrat methods. Perpendicular to the shoreline, three (3) 100-m transect lines at 200-m interval between each transect were laid. Seven seagrass species were recorded comprising 38.6% of the total number (19) of seagrass species found in the Philippines. The seagrass community in all sites surveyed showed that it is highly dominated by Thalassia hemprichii species. However, there were no significant differences in species richness and diversity based on single-factor ANOVA statistical analysis (p>0.5). The abundance of T. hemprichii could probably be due to the prominent characteristic of this species where it could grow well in different types of habitat with various environmental conditions. The condition of seagrass beds in both areas were fair and the low Shannon-Wiener Diversity Index of seagrass in Kauswagan, Lanao del Norte (H’=0.76±0.22) and in Laguindingan, Misamis Oriental respectively (H’=0.40±0.35) indicate low stability in the community, which means that the condition of the seagrass ecosystem could be under threat, both from natural and anthropogenic activities. Over time, a fluctuating trend in species composition and a notable decline in seagrass species diversity and abundance have been observed in both areas. This present status calls an immediate response from the decision makers concerned for the sustainable management and conservation of the seagrass resources.

A Review of Environmental Implications of Dredging ActivitiesIJAEMSJORNAL
Dredging is a global anthropogenic excavation activity of removing sediments from water bodies and depositing it elsewhere. It is a mixed blessing as it has both beneficial and adverse impacts. This paper is on a review of environmental implications of dredging. The objective of the paper is to review previous works by researchers on the environmental consequences of dredging. The method used is a review of academic/journal articles, internet materials, conference / workshop papers, textbooks, bulletins and publicly available materials on dredging activities. The results of the study revealed that previous authors whose works were reviewed have a convergent view that apart from the beneficial impacts of dredging (e.g. keeping waterways navigable, flood and storm protection and provision of materials for road construction and building), it has lots of adverse environmental impacts, including environmental pollution, erosion, widespread hydrological changes, reduction in the population of aquatic lives like destruction of fish spawning grounds and benthic organisms and resuspension of particulate matter column that has elevated levels of lead, copper, zinc and nickel in Phytoplankton. Recommendations of the study include: (1) establishment of environmental legislations and regulations for dredging operation; (2) use of green technology in dredging activities to minimize suspension of sediments and contamination/pollution of dredging environments; and (3) creation of awareness among dredging contractors, regulators and marine communities where dredging take place on the economic and ecological values of the marine ecosystems that are usually very sensitive, fragile and productive.

A MODEL TO ESTIMATE STORED CARBON IN THE UPLAND FORESTS OF THE WANGGU WATERSHEDAsramid Yasin
Abstract
Climate change coupled with deforestation has brought about an increase in greenhouse gas emissions in the
atmosphere. One way to control climate change is to reduce greenhouse gas emissions by maintaining the integrity
of natural forests and increasing the density of tree populations. This research aimed to (a) identifies the density
of stand trees in the upland forests of the Wanggu Watershed; (b) analyze the potential carbon stocks contained in
the upstream forests of the Wanggu Watershed; (c) develop a model to estimate potential carbon stocks in the
upland forests of the Wanggu Watershed. The land cover classification in this study used the guided classification
with the Object-Based Image algorithm. Normalized Difference Vegetation Index (NDVI) was employed as an
indicator of vegetation cover density. Field measurements were carried out by calculating the diameter of the stand
trees in 30 observation plots. Field biomass values were obtained through allometric equations. Regression analysis
was conducted to determine the correlation between NDVI densities and field biomass. The results showed that
the best equation for estimating potential carbon stocks in the Wanggu Watershed forest area was y = 3.48 (Exp.
7,435x), with an R2 of 50.2%. Potential above ground biomass carbon in the Wanggu Watershed based on NDVI
values was 414,043.26 tons in 2019, consist of protected forest areas of 279,070.15 tons and production forests of
134,973.11 tons. While total above biomass carbon based on field measurement reached 529,541.01 tons, consist
of protected forests of 419,197.82 tons and production forests of 110,343.20 tons.

Paper Title
Particle Swarm Optimization–Long Short-Term Memory based Channel Estimation with Hybrid Beam Forming Power Transfer in WSN-IoT Applications
Authors
Reginald Jude Sixtus J and Tamilarasi Muthu, Puducherry Technological University, India
Abstract
Non-Orthogonal Multiple Access (NOMA) helps to overcome various difficulties in future technology wireless communications. NOMA, when utilized with millimeter wave multiple-input multiple-output (MIMO) systems, channel estimation becomes extremely difficult. For reaping the benefits of the NOMA and mm-Wave combination, effective channel estimation is required. In this paper, we propose an enhanced particle swarm optimization based long short-term memory estimator network (PSOLSTMEstNet), which is a neural network model that can be employed to forecast the bandwidth required in the mm-Wave MIMO network. The prime advantage of the LSTM is that it has the capability of dynamically adapting to the functioning pattern of fluctuating channel state. The LSTM stage with adaptive coding and modulation enhances the BER.PSO algorithm is employed to optimize input weights of LSTM network. The modified algorithm splits the power by channel condition of every single user. Participants will be first sorted into distinct groups depending upon respective channel conditions, using a hybrid beamforming approach. The network characteristics are fine-estimated using PSO-LSTMEstNet after a rough approximation of channels parameters derived from the received data.

Abstract: Coastal geomorphology deals with the
various landforms and different processes involved
in the development of coast. In the alluvium coast,
biology plays a significant role as a coastal process.
The present study aims at the role of vegetation in
the geomorphic system, with the main
consideration of flora. The study has been
conducted in an alluvium coast along the Bay of
Bengal adjacent to the sections of Balasore and
Kanthi coastal plain. The geomorphological map
and Normalized Difference Vegetation Index
(NDVI) have been generated with the help of
Landsat 5 TM, Landsat 8 OLI & SOI Toposheet
with the help of Arc GIS & Erdas Imagine
software. The ground truthing of relationships
between geomorphological units & vegetation
types are established with the help of GPS survey
and counting of species type. The selected nine
environmental transects of Balasore and Kanthi
coastal plains i.e. Dagara, Kankadapal, Talsari,
Udaipur, Digha, Shankarpur, Tajpur, Mandarmani
& Junput have been considered for assessing the
role of vegetation in sediment accretion and
sediment surface stability. The study shows that the
surface stability is achieved with dense vegetation
covers and their types in Mangrove Swamp, Salt
marsh and sand dunes whereas; the erosional area
of geomorphic units has less vegetation cover and
insignificant species type. The perfect relationship
are found in the shore transect of Balasore-Kanthi
coastal interface area (New Digha to Bichitrapur).
Finally, it is also observed that the above area is
less disturbed by human activities in compare to
others.

I. INTRODUCTION
The Coastal morphology deals with the
understanding of the landforms structure produced
due to the erosional and depositional activities of
the coast. The coastal morphology is a broad
concept to discuss the relationship between the
formation of erosional and depositional features.
The predicted sea-level rise may produce the
impacts on the coastal ecosystem as well as on the
coastal inhabitations made by the people at the sea
shore [15,16]. There are several methods for the
estimations of coastal vulnerabilities to assess the
impacts of different physical and environmental
hazards. The morphological variations at the
geographical space subjected to process variables
and concentration of energy made the alluvium
coast as dynamic landform with events of erosion,
deposition & transportation [4,6,7] The
morphological structures are formed due to the
high interaction of wave, tide, wind, current and
grain sizes. The change of the morphology due to
the processes led to the formation of numerous
features. The present study area is highly
susceptible to sea level rise and climate change
impacts. Effective coastal zone management is
needed to increase the resilience capacity of such
coast for reduction of hazards on the infrastructural
development and human settlement [3]. The coastal
zone is a very complex environment, where the salt
water meets the fresh water.
The terrestrial part of the coastal zone with its
freshwater influx and sediment source as well as
groundwater resources influences the marine
environment along the coastal fringes and the
marine area with its saltwater, storms, tides,
currents & storm surges influence the landward
part of the same coast [6]. The coastal zone
represents varied and highly productive ecosystems
such as mangroves, sea grasses and sand dunes.
Today’s coastal habitats of the alluvium shore line
are highly converted by local people for
urbanization, dense settlements & infrastructure
developments, which is other ways are responsible
for the loss of coastal wetlands, unpredictable
siltation and environmental degradation [18,19,21]
(Fig.1). The future expansion in many undeveloped
maritime countries will also be concentrated on
coastal areas. Any human activities may cause
dramatic change in the ecosystem functions of the

coastal habitats. Coastal development contributes to
habitat loss in many ways. In the previous decades,
the frequency of high magnitude cyclones as well
as moderates magnitude of cyclones is increased in
the tropical coast [20].
Coastal features at the interface of land and sea
(beaches, sand dunes, wetlands, barrier islands,
reefs etc.) act as physical barriers against storm
damage. Mangroves, sand dunes sea beaches & salt
marshes are traditionally acted as coastal buffer
against the strong sea waves, erosion intensity and
cyclone landfalls in the low lying alluvium coasts
[18,9]. The loss of such buffers by the human
activities in the coast is directly responsible for the
impact of low magnitude and moderate magnitude
cyclones. The coastal vulnerability is rapidly
increased due to industrial development,
urbanization, agricultural practices, destruction of
forests, fossil fuel burning, development of the
transport system, draining wetlands, the adoption of
modern technology in farming and livestock
rearing etc. [2,11,13] Thus, studies on the genesis,
evolution and process involved in the formation of
the surface forms of the coast represent its dynamic
system which must be considered for various
management policies to be adopted by
environmental managers along the coast. The
relative exposures of coastal engineering structures
to the waves, currents & storms have weakened the
secondary stability factors along the coast [1].
Coastal zones are naturally very dynamic and
economically highly productive which have been
adversely affected by the impact of extreme natural
events like tsunami, cyclonic storm surge, severe
erosion and increased sea surface temperature as a
result of global climatic changes over the past
century. The alternate sequences of the temperature
changes of the earth are recorded since ~ 1900 to
1940 experienced warm temperatures and during
~1940 to 1965–1970 experienced relatively cool
temperature and finally after 1970 onwards, the
earth experienced warm temperature [8,22]
Geomorphology, ecology and, society of the coast
offer most significant aspects of modern
environmental issues for the coastal studies in
different disciplines. Most of the hazards are turned
into disastrous activities due to the inability of the
potentially vulnerable communities due to
socioeconomic inequalities, their proximity to the
hazardous event, high population density, the
degree of awareness and understanding, and poor
infrastructure [14]
Fig.1: Soil Profile Zones along Bichitrapur
II. COASTAL ZONE MANAGEMENT
The progress made in remote sensing technologies
and geographical information systems (GIS)
represents an important contribution enabling us to
face up to this challenge [5]. Coastal zone
management, disaster management, environmental
impacts analysis, and coastal zone regulation acts
are the burning issues of the modern coasts. Coastal
zones are geomorphologically dynamic,
ecologically sensitive, biologically productive and
rich in habitat diversity, and environmentally
hazard prone under the events of tropical cyclone,
tidal waves, climate change and sea level rise.
Today, people are attracted by the available
resource, space for various development activities,
recreational facilities and various scopes for
industrialization around the coasts. The low-lying
coastal alluvial plains of the lower Ganga delta,
Subarnarekha delta and Kanthi coastal tract are
heavily populated at present. The combined
impacts of increasing coastal populations at
unprecedented rates, expected rise in sea level due
to greenhouse induced warming and local
subsidence rates will put significant stress on the
coastal zones of the present study areas in the near
future. The coastal zone stands as a collision course
between the two ways of change – human related
development changes and expected natural changes
[17]. Today, the major threat to the coastal zone
comes from the maritime disasters particularly
resulting from estuarine pollution, marine
pollution, over exploitation of natural resources at
sea and high magnitude of cyclones. The damage is
regularly caused by the southwest monsoon brace
and the frequent cyclones are well known
particularly around the low-lying coasts.

IV. MATERIALS & METHODS
In order for carrying out present study, a detailed
plan of field observation had been prepared for the
identification of species (Table.1). The
methodology used in the present study is estimated
using the relationship between geomorphic features
and vegetation species in the coastal morphology.
The coastal geomorphological map is generated
from the Landsat 8 (OLI) image of 2017 & Landsat
5 TM, Toposheet and Google by overlaying
processes then vectorization of geomorphological
classes has been done with the help of GPS Survey
to identified geomorphological units by using Arc
GIS 10.1 Software. Geomorphological features and
Vegetation are identified in the ground truth
verification with the help of random way in GPS
Survey and also analysis in the Balasore to Kanthi
coastal region to demarcate in the statistical
frequency graph in the based on geomorphic units
and the no of vegetation species (Fig.3).

V. RESULTS & DISCUSSION
The Drainage map helps us to identify the drainage
features and its evaluation. The study area is
showing concentration of dendritic pattern (Fig.4).
From the south-western part to north-eastern part
Digha river mouth lies under Digha coast, Jaldah
river mouth lies between Shankarpur and
Mandarmani coast. Pichaboni river mouth lies
between Mandarmani and Junput coast but the
major river estuary in the study area is
Subarnarekha. This estuaries and river mouths
mixes in the ocean of Bay of Bengal. These all

VI. RELATIONSHIP BETWEEN
VEGETATION AND GEOMORPHIC UNITS
The colonization of vegetation in different
geomorphic units of sedimentary landforms
produces surface stability and increase the rate of
sediment accretion. However, the sand dunes and
vegetated tidal flats of the coastal zones are getting
affected seriously by the formation of blow out
spots on the sand dunes and increased rate of sheet
erosion from the exposed tidal mud banks after the
alarming rate of vegetation removal process by
human induced activities in the coastal zone (i.e.
land use conservation). Gradually, the surface
stability of shoals and bars is achieved with the
siltation rate and colony development of halophytic
vegetations, and as the colony development spreads
over the surface with time the accumulation rate of
sediments increase the surface elevation and
horizontal expansion of island platforms in the
alluvium coast of the region with rapid supply of
sediments in the monsoon phases by River
Subarnarekha and River Hooghly [12]. The
presence study also highlights the significance of
vegetation colony development and frequency of
species types with various geomorphic surfaces to
establish the positive relationship between
geomorphology and vegetation covers. The
significance of vegetation colony development &
their existence should be carefully considered, in
term of the sensitivity of sedimentary landforms to
the biological process in the coast (Fig.7 & 9).
VII. THE OPEN COAST BACK BARRIER
TIDAL FLAT OF SUBARNAPUR – TALSARI
AREAS (ORISSA COAST)
Salt marshes and Mangroves coexist in a Narrow
tidal Basin of Subarnarekha Delta under lagoonal
setting and estuarine setting of the tropical coastal
zone protected by a barrier spit extended along the
shoreline of the Bay of Bengal. The enclosed coast
line of the delta area is significant site for a net
accumulation of sediments (tidal, marine and
estuarine). Indeed the water and sediment regime
are the two prime factors in marsh establishments,
growth and differentiation. Such rooted plans of
terrestrial origin cannot grow systematically unless
the sediment accretionary surface is stable enough
permit the rooting and growth habits of vegetations.
The linear tidal basin is extended from the mouth
of the Subarnarekha River to the east-north-east
direction with 7 kms in length and 0.5 km. to 1.80
kms. In width, and sharply fed by Talsari –
Subarnapur tidal inlets across the barrier sand spit.
A large colony of mangroves or halophytic
woodland vegetations is restricted on the banks of
Subarnapur tidal channel on the western part of
tidal basin close to the river mouth environment of
Subarnarekha (Table.2; Fig.8).

VIII. SALTMARSH VEGETATION OF
DIGHA MOHONA
Bothe above - ground and underground conditions
are very significant to the saltmarsh ecosystem.
Above - ground waters come from the tidal
flooding and local rainfall and the underground
water relations of saltmarsh area are influenced by
the above - ground ones and by drainage and
seepage conditions. Thus the physical properties
like tides, their period, amplitude and the subtract
character of the saltmarsh have an influence on the
zonation pattern of vegetation have started from the
bare mud of the creek banks to the higher surface
of saltmarsh. The shelving mud banks and the
shallow mud flats are predominantly occupied by
Porteresia coarctata (Dhanighas). This type of
vegetation prefers the swampy floor and newer
mud accreted surface for adjustment to the dynamic
environment of saltmarsh. The sloping flat above
this zone of vegetation with less frequent
inundation, is mostly colonized by the species of
Aeluropus lagopoides (Nona Durba). Finally, the
higher marsh surface is densely colonized by
Salicirnia brachiata (Brahmmi sak) and Suaeda
maritime (Giria sak) species. Salt concentration is
also comparatively high in this surface than other
areas of the saltmarsh due to the higher rate of
exposure and evaporation (Table.3)
These are the three distinctively zones of saltmarsh
vegetations in the saline wetland of Digha coast.
Except these, some other vegetation is also
frequently distributed in the swampy flats. Among
them Suaeda nudiflora (Sada Giria sak),
Avicenmia officinalis (Sada Bain), Acanthus
ilicifolious (Harkach kanta) etc (Fig.9) are
remarkable. Recently scattered distribution of
Sesuvium portulacastrum (Gadabani sak) is also to
be found in the sandy surface of creek banks and
around salt - encrusted surface of the saltmarsh.
Thus, with the density of the saltmarsh vegetations
the sediment accretion process slowly and
gradually by which maturation process of the
saltmarsh topography is promoted. The mud flats
and creek bank sand flats also provide attachment
surface for a small number of algal communities in
the saltmarsh habitat.

IX. CONCLUSION
Sediment stockpiling takes place in the tidal
mudflats with the baffling effects of salt marsh and
mangrove vegetations in the period of tidal
inundations as do sand dunes in the beach fringed
areas with blocking effects of shoreline vegetations
in the period of windblown sand movement in the
sandy coast. The present study shows that the
windblown depositional layers between two
successive decomposed organic layers trapped in
the past sedimentary sections are varying in
thickness which exposed in the erosive section of
dune cliffs at present all along the coastline. From
measuring records it is proved that windblown
Fig.9: Relationship between geomorphological units &
vegetation species in the coastal tract of Balasore & Kanthi
deposits might ranges from 8cm. to 12cm. per year
in the coast preferably induced by vegetation
obstructions and micro-topographic variations in
the coastline (Fig.10). The sediment accretion rates
may vary from saltmarsh areas, and mangrove
dominated areas to sand dunes of active vegetation
covers in the coast but sediment surface stability
provided by them depend on less storminess of the
sea, shoreline configuration and shelted areas of the
coast. Buffering capacity of vegetation also differ
from plant to plant in areas of more sediment
supply and less sediment supply. Thus, fresh silts
are stabilized in many cases by colonization of
Avicennia sp. and Rhizophora sp. at the shorefront
positions of the Kanthi coastal plain. Porteretia
coarctata and Oryza coarctata at lower saltmarsh
and surface stability is achieved by colonization of
Sesuvium portulacustrum and Ipomea sp. at the
fore dunes of the sandy coast. However, in the hot
and dry summer phase when most of the dune
herbs and grasses become dried out only Spinifiex
litorious and Cyperus exultantus survive with
strong buffering capacity against windblown sand
deposition, high surface temperature, low field
moisture and strong wind velocity (35km/hr. to 50
km/hr.) at the open shore environment of West
Bengal and Orissa coasts.
