Flood modelling studies : unsteady flow analysis with HEC-RAS

, 2014
HEC-RAS is a River Analysis System developed by the U.S. Army Corps of Engineers that allows the performance of one-dimensional hydraulic calculations for a full network of natural and constructed channels for steady and unsteady flow.

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 ...

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.

Dam breach model of Lake Anza Dam using HEC-RAS

, 2018
For this project, HEC-RAS was used to create an inundation map for the failure of the Charles Lee Tilden Dam in Berkeley, California. A two-dimensional HEC-RAS model was created to simulate the Lake Anza Reservoir, C.L.
