To compute the rainfall depth on the sub-basins of the MODRAT model, read in a rainfall depth data layer. The isohyetal maps for LA County have been digitized and stored in ARC/INFO® Grid format by the LACDPW; these files can be found in the /MODRAT/Rain/ folder installed with WMS. Import this data by choosing Open from the File menu, then choose Rainfall Depth Grid (*.*) as the file type. This creates a rainfall grid folder 
in the Project Explorer which can contain multiple rainfall grid objects 
.
Alternatively, if there are other rainfall data in vector format (ArcView® Shapefiles, DXF, etc.) import these into WMS. Make sure to create a Rainfall Coverage (see the Coverages dialog) and map the appropriate database fields when importing this data.
Once the rainfall depth data is present in WMS, compute and assign depths using the Compute GIS Attributes command from the Calculators menu.
