Rainfall:Spatially and Temporally Varying Rainfall
The ability to assign uniform rainfall over the entire watershed is maintained largely as a trouble-shooting feature and is mostly used in initial model development. Real watersheds are modeled with temporally and spatially varying rainfall. As briefly described in Chapter 3, all precipitation inputs are created in WMS by selecting Precipitation from the GSSHA Menu while in the 2-D Grid module. This will bring up the GSSHA Precipitation dialog box. How to assign temporally varying rainfall for one or more gages is described below.
