In HEC-RAS 2D Rain-on-Grid (ROG) modeling, three layers are needed to model the infiltration loss and the procedures to create the three layers have been discussed before. Land Cover Layer…

To model infiltration loss within 2D domain for a Rain-on-Grid (RoG) HEC-RAS model, a land cover layer and a soils layer needs to be generated first and then an infiltration…
In HEC-RAS 6.0, users have the option to import either raster landcover files or vector landcover files to create a land cover layer which will then be used to associate…
This post (3 of 3) is an instruction of combining Land Cover Raster file and HSG Raster file to create a CN raster file for calculating an area-weighted average CN…
The SCS (NRCS) Curve Number is used to quantify infiltration loss during runoff calculation. As illustrated in Figure 1, the CN is determined by both soil types (Hydrologic Soil Groups,…
