Nr of distributed processors
Nr of shared processors
Start year development	1988
Does model development still take place?	Yes
If above answer is no, provide end year model development
Code development status
When did you indicate the 'code development status'?
Model availability	As code, As teaching tool
Source code availability (Or provide future intension)
Source web address
Source csdms web address
Program license type	Other
Program license type other	--
Memory requirements	Depends on catchment
Typical run time	depends on catchment size and process algorithms selected

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
Other input format	US Dept. of Defense Watershed Modeling System (WMS)
Describe output parameters	Flow rates, depths, soil moisture, sediment fluxes, erosion/deposition, contaminant/nutrient fluxes and concentrations, groundwater levels, reservoir storages.
Output format	ASCII, Binary
Other output format	US Dept. of Defense Watershed Modeling System (WMS)
Pre-processing software needed?	No
Describe pre-processing software
Post-processing software needed?	Yes
Describe post-processing software	yes, The US Dept. of Defense Watershed Modeling system can produce animations of model outputs. Run summary file includes detailed mass balance information. Output time series can be analyzed using spreadsheet or other software.
Visualization software needed?	Yes
If above answer is yes
Other visualization software	Dept. of Defense, Watershed Modeling System (WMS)

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
Describe key physical parameters and equations	Too much to describe in only 500 characters! See: http://www.gsshawiki.com/wiki/index.php5?title=Main_Page
Describe length scale and resolution constraints	Dependent upon computational power and memory.
Describe time scale and resolution constraints	Dependent upon computational power and memory.
Describe any numerical limitations and issues	Explicit finite volume routing formulations are time-step limited.

Describe available calibration data sets	http://www.gsshawiki.com/wiki/index.php5?title=Main_Page
Upload calibration data sets if available:
Describe available test data sets	http://www.gsshawiki.com/wiki/index.php5?title=Main_Page
Upload test data sets if available:
Describe ideal data for testing	--

Do you have current or future plans for collaborating with other researchers?	The development of GSSHA has been funded by the US Army Corps of Engineers, Engineer Research and Development Center, Vicksburg, Mississippi. GSSHA is being actively used by a number of US Army Corps of Engineers districts.

Is there a manual available?	Yes
Upload manual if available:
