WebThe goal of this Flood Hazard Mapping Recommended Practice is to evaluate the possible inundation extent in a river reach using the basic functions of RAS Mapper in HEC-RAS to create a 1D model of a river system. Mapping the results of a hydrodynamic model to determine the inundated areas is important in order for: WebDec 14, 2024 · This post will cover Option B: “Between 2 XS’s”. Between 2 XS’s simply means HEC-RAS will interpolate cross sections ONLY between two selected “non-interpolated” cross sections. It will not interpolate over a reach. Obviously the disadvantage here is that you have to interpolate between pairs of cross sections one-at …
