Rainfall:Temporally varying, spatially uniform rainfall
Temporally varying, spatially uniform rainfall can be assigned by toggling on the Single Gage Rainfall button. A single-gage rainfall produces a time series of rainfall for the entire watershed. The time series is specified by clicking Define Event and entering the time series with the X,Y data series editor. A single rain gage event can also be constructed in the same manner as described below, where spatially and temporally varying rainfall simulations are discussed in more detail. For a single temporally varying rain gage, the maximum number of rainfall data points in the time series is limited to 1,500. Larger rainfall events can be modeled by GSSHA but cannot be brought into WMS for manipulation. These rainfall files, as well as multiple rain gage files, can be constructed with an editor outside of WMS, and then this file can be named as the rainfall file when saving the GSSHA project file.
