MODSIM-DSS ia an open-source decision support system with a graphical user interface (GUI) that allows users to create any river basin topology. The system can account for surface water rights, storage rights, instream rights, and water availability. Operates on desktop computers operating under MS Windows using the .NET Framework. GEO-MODSIM, is a full implementation of MODSIM operating as a custom extension in ArcGIS (ESRI, Inc.), allows automatic generation of MODSIM networks from geometric networks and processing of spatial database information in a GIS.
Applicable throughout the western United States or in regions with comparable water allocation systems.
Surface water data and water rights data
Water availability at nodes and potential system optimization
Linkage to Other Models
Input from MODFLOW groundwater models has been linked to MODSIM
Level of Effort
This model requires a strong understanding of water rights and local knowledge of the system. It requires an up-front investment in understanding MODSIM and developing the model.
