Goal
• The main goal of this research was to apply and test the application of two hydrologic models (HSPF and GSSHA) to predict overlandflow in the Luxapallila Creek watershed (1,858 km2 rural watershed), located in Alabama and Mississippi.

EPA HSPF is a comprehensive water quantity/quality watershed model. Hydrology is simulated using a physically based water budget scheme with empirical equations among the different components (interception, infiltration, evapotranspiration, surface runoff, etc).
USACE GSSHA is a physics-based multidimensional watershed model. While runoff excess calculations in the HSPF model use the soil
infiltration rate, the GSSHA model applies the soil hydraulic conductivity, along with a number of other soil parameters to compute a more physically based infiltration rate.
GSSHA, like HSPF, also under simulated runoff during most of the evaluated storm events.
This study found that the GSSHA model had a better performance than HSPF runoff results when calibrated parameters were evaluated in a sub-watershed outlet.
GSSHA was more computationally intensive and less efficient than HSPF: numerical solution-based scheme vs analytical solution 185,816 cells vs. 50 sub-watersheds 20 hours vs. 5 seconds (Dual Core AMD Opteron(m) 3 GB of RAM)
