|Extended model description=Gridded Surface Subsurface Hydrologic Analysis (GSSHA) is a grid-based two-dimensional hydrologic model. Features include 2D overland flow, 1D stream flow, 1D infiltration, 2D groundwater, and full coupling between the groundwater, vadoze zone, streams, and overland flow. GSSHA can run in both single event and long-term modes. The fully coupled groundwater to surfacewater interaction allows GSSHA to model both Hortonian and Non-Hortonian basins.

In/Output

Describe input parameters DEM, land-use/land-cover, stream channels, precipitation, soils, aquifer maps. These index maps are used to classify catchment parameters related to overland/channel flow, soil/aquifer hydraulic properties, soil erodibility, contaminant loadings, etc. Model setup is greatly enhanced by the use of the US Dept. of Defense Watershed Modeling System (WMS), which serves as an interface between GSSHA and Arc/Info
Input format ASCII, Binary

Process

Describe processes represented by the model Processes:
  • Rainfall: gage with nearest neighbor or inverse distance-squared weighting, radar.
  • Interception: empirical model.
  • Infiltration: Green & Ampt, Green & Ampt with redistribution, three-layer Green & Ampt, or Richard's equation.
  • Overland runoff: 2-D finite volume diffusive wave with overland flow dykes and pothole lakes.
  • Channel routing: 1-D dendritic finite-volume diffusive wave with culverts, on-channel lakes, rule curves, rating curves, scheduled releases.
  • Groundwater: 2-D finite-difference with wells and various boundary conditions.
  • Overland erosion: three alternative source equations, raindrop impact, erosion limits, deposition, arbitrary size classes.
  • Channel sediment transport: advection-diffusion for fines, stream power for sands.
  • Fate and transport of conservative and non-conservative

constituents in soil, overland, and channels
