A Novel Hybrid Deep-Learning Approach for Flood-Susceptibility Mapping

Remote Sensing
Flood-susceptibility mapping (FSM) is crucial for effective flood prediction and disaster prevention. Traditional methods of modeling flood vulnerability, such as the Analytical Hierarchy Process (AHP), require weights defined by experts, while machine ...

FLOOD MODELING OF RIVER GODAVARI USING HEC-RAS

International Journal of Research in Engineering and Technology, 2014
Many cities and towns are developed on downstream side of dams. Some of them are established on the banks of river. During the monsoon period, when the dam is full at its Maximum Reservoir Level (MRL) and still the surplus floods are approaching into dam submergence, the maximum discharge is released from the dam to avoid the overtopping.

HEC-RAS Model for Mannnig’s Roughness: A Case Study

Open Journal of Modern Hydrology, 2013
Channel roughness is considered as the most sensitive parameter in development of hydraulic models for flood forecasting and flood inundation mapping. Hence, it is essential to calibrate the channel roughness coefficient (Mannnig’s “n” value) for various river reaches through simulation of floods.
