To compute the soil number for each sub-basin of a MODRAT model, read in a soil type data layer. Soil type data is generally stored in a GIS, the best way to read it into WMS is though a Shapefile. To import soil type data for use with MODRAT, create a Soil Type Coverage, then import the polygon file and ensure that the Soil Number field (often called CLASS_NO by the LACDPW) is assigned to LA County Soil type field of WMS. Once the soil type data is present in WMS, compute and assign soil numbers using the Map Attributes command from the MODRAT menu.
