Water Balance Model for a Pervious Catchment (from HSPF)
This GoldSim model does the calculations of the pervious catchment water balance module of the Hydrologic Simulation Program Fortran (HSPF-PERLND PWATER module). HSPF is one of the most widely used conceptual rainfall runoff models
. It models surface runoff, interflow, and groundwater outflow as a function of watershed parameters and input rainfall and pan evaporation data. I have recently modified it to allow uncertainty in input parameters and hence the runoff response. A user manual is provided and it describes the good agreement in comparisons between GoldSim's calculations and those of HSPF.
