Hello there, I am working on a narrow/ shallow creek which got some farmers field/ wetland areas. So when i am using my peak flow from SWMHYMO hydrologic model to steady flow analysis in HEC RAS it over topped the banks and goes like 1 km of huge wide floodplain. Its basically low velocity/ less flood depth and stagnant water. How to model these storage area (I dont have any discharge information from these wetlands). Is it possible to use steady flow analysis instead of unsteady analysis here? Is it a good practice to reduce these flood volume, so that downstream area will have less flood plain? If I consider these wide flood plain in 1 D steady HEC RAS model how much over estimating I am considering downstream? Thanks.
