GSSHA can produce a variety of outputs for the user. GSSHA automatically outputs a run summary file, which has the extension .sum, and an outlet hydrograph file, which has the extension .hyd. GSSHA can also output time series data for a number of variables at any point in the channel network and in the 2-D grid. GSSHA can produce a series of maps that can be displayed in WMS containing surface depth and/or other results. Once the simulation has been completed, results can be read back into WMS as a solution for post-processing. This chapter discusses the different output options available from GSSHA and a few of the methods available in WMS for viewing these computed results.
