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…
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…
Hydrologic Soil Group Data (A, B, C, and D) is an important soil property which impacts the soil infiltration rates and runoff potential. Soils were originally assigned to hydrologic soil…
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,…
