Sediment is any particulate matter that can be transported by fluid flow and eventually deposited. There are four main categories of sediments based on size: gravel, sand, silt, and clay. Incipient motion, or the initial movement of sediment particles, is important to studying sediment transport and channel design. Two main approaches to modeling incipient motion are the shear stress approach and velocity approach. Shields developed a widely used diagram relating the critical shear stress needed to initiate motion to other dimensionless parameters like particle size, fluid properties, and sediment density. White's analysis also models critical shear stress as proportional to particle size. The velocity approach uses field surveys of permissible flow velocities before sediment starts moving in different channel materials.

Ground penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. It can detect objects, changes in material, and voids or cavities underground. GPR works by transmitting electromagnetic pulses into the ground and measuring the time it takes for the pulses to reflect back to a receiver antenna. Different materials and objects underground cause different reflections that appear as hyperbolic patterns in GPR images. GPR systems consist of a transmitter antenna, receiver antenna, control unit and display. The frequency used depends on the desired depth of penetration and resolution needed. GPR has advantages of being non-invasive, fast, and able to provide 3D images of underground structures, but its effectiveness is limited by certain soil or terrain conditions.

In this deck from the Stanford HPC Conference, Peter Dueben from the European Centre for Medium-Range Weather Forecasts (ECMWF) presents: Machine Learning for Weather Forecasts.
"I will present recent studies that use deep learning to learn the equations of motion of the atmosphere, to emulate model components of weather forecast models and to enhance usability of weather forecasts. I will than talk about the main challenges for the application of deep learning in cutting-edge weather forecasts and suggest approaches to improve usability in the future."
Peter is contributing to the development and optimization of weather and climate models for modern supercomputers. He is focusing on a better understanding of model error and model uncertainty, on the use of reduced numerical precision that is optimised for a given level of model error, on global cloud- resolving simulations with ECMWF's forecast model, and the use of machine learning, and in particular deep learning, to improve the workflow and predictions. Peter has graduated in Physics and wrote his PhD thesis at the Max Planck Institute for Meteorology in Germany. He worked as Postdoc with Tim Palmer at the University of Oxford and has taken up a position as University Research Fellow of the Royal Society at the European Centre for Medium-Range Weather Forecasts (ECMWF) in 2017.

It then reviews related work on weather prediction using machine learning methods. The proposed method involves collecting weather data, preprocessing it, converting it to a stationary time series, analyzing it using an ARIMA model, and concluding that ARIMA can accurately predict weather patterns to help tourists plan trips based on the forecast.
IRJET- Flood Alerting System through Water Level MeterIRJET Journal
This document describes a flood alerting system that uses sensors to measure water levels in rivers and lakes. A micro-model is designed using a programmable electronic board connected to electrical resistances placed at different heights in a water container. When the water level reaches a resistance, the sensor transmits the information via WiFi to computers and smartphones so users can see the water level. The system aims to provide timely information to residents in low-lying areas about changes in water levels and predict safe water levels to save lives during floods. Experimental tests of the micro-model produced acceptable results.

6. Introduction
All of the natural disasters, floods are the most destructive, causing massive damage to human life,
infrastructure, agriculture and the socioeconomic system. Governments, therefore, are under pressure to
develop reliable and accurate maps of flood risk areas and further plan for sustainable flood risk
management focusing on prevention, protection and preparedness.
Flood prediction models are of significant importance for hazard assessment and extreme events
management. Robust and accurate prediction highly contributes to water recourse management strategies,
policy suggestions and analysis, and further evacuation modeling. Thus, importance of advanced systems for
short-term and long-term prediction for flood and other hydrological events are strongly emphasized to
alleviate damage. However, prediction of flood lead-time and occurrence location is fundamentally complex
due to the dynamic nature of climate condition.
Therefore, today’s major flood prediction models are mainly data specific and involve various simplified
assumptions.

26. Conclusion
We developed a different model, using a rainfall-flow pattern based on historical rainfall and
flood flow data for real-time predictions of short-term flood stream-flow.
Our models predict the flood process line in real-time using hydrological feature extraction
and spatial-temporal metrics for similar rainfall flow patterns. The experimental results based
on the datasets of various models in wet and drought-ridden watersheds show that the
proposed models offer considerable advantages in accurately predicting the peak time of
floods in real time.
we will consider large-scale watershed discharge forecasts and other types of discharge
forecasts (such as urban underground drainage and high-sand rivers) forecasts. Finally, a
fusion of radar rainfall data and ground station data could be developed.
