There are two required output files for each GSSHA simulation. These two files are specified with the OUTLET_HYDRO and SUMMARY project file cards, and contain the hydrograph at the catchment outlet and a summary of model performance, respectively (Table 21).

In addition to specified outputs GSSHA automatically outputs a file called MASKMAP which is an GRASS ASCII map of the cell numbers as stored internally within GSSHA. This file can be used to locate problem cells when GSSHA gives a message referring to the cell number, instead of the i and j location. When continuous simulations are performed GSSHA also outputs a file called evap_out which list basin wide average hourly values of: soil moisture, potential evaporation (cm hr-1), actual ET (cm hr-1), infiltration rate (cm hr-1), groundwater recharge (cm hr-1), continuous frozen ground index, temperature (C), gridded temperature (C), surface soil temperature (C).
