SEAWAT is a combined version of MODFLOW and MT3DMS for simulation of variable-density groundwater flow and transport.

The Surface-Water Routing (SWR) Process is used to accurately simulate stages, surface-water flows, and surface-water/groundwater interactions in areas where surface-water gradients are small and/or there is significant management of surface water.

Estimation of Baseline Daily Mean Streamflows for Ungaged Locations on Pennsylvania Streams, Water Years 1960–2008

The Central Valley Hydrologic Model (CVHM) is an extensive, detailed three-dimensional (3D) computer model of the hydrologic system of the Central Valley (Faunt, 2009). The Central Valley Hydrologic Model (CVHM) simultaneously accounts for changing water supply and demand across the landscape, and simulates surface water and groundwater flow across the entire Central Valley.

The purpose of the Physical Habitat Simulation System (PHABSIM) is to simulate a relationship between streamflow and physical habitat for various life stages of a species of fish or a recreational activity.

Smart River GIS allows simultaneous views of river hydraulics, species-specific habitat, and fish population simulations, for a better understanding of complex ecological interactions. We used existing data sets from the South Platte River in Colorado to develop a multi-layered geographic information system (GIS) that resource managers can use to improve their understanding of river...
