WebSep 17, 2015 · HEC-RAS will automatically take the name of the upstream of the two rivers for the new combined reach. You can change the name of the river and/or reach using the Edit…Change Name menu item. It is very important that your river stationing for the two reaches are consistent prior to doing this operation, or it will not work. 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:
