WebMay 13, 2024 · Unsteady flow analysis is carried out by using HEC-RAS to detect the change in flooding pattern for 21 years and the results are mapped with ArcGIS. These flood inundation studies and the maps created will help the decision makers to assess the risk and to take precautions at the earliest. WebHEC-RAS allows for two main types of simulation: steady and unsteady state analysis. In steady state analysis, constant boundary conditions are entered, whilst for unsteady it is included a hydrograph.
