Concise description:

An integrated hydrologic model called GSFLOW (Ground-water and Surface-water FLOW) was developed to simulate coupled ground-water and surface-water resources.GSFLOW simulates coupled groundwater/surface-water flow in watersheds by simultaneously computing flow across the land surface and within streams and lakes as well as within subsurface saturated and unsaturated materials. Climate data consisting of measured or estimated precipitation, air temperature, and solar radiation, as well as groundwater stresses (such as withdrawals) and boundary conditions are the driving factors for a GSFLOW simulation. The model is appropriate for evaluating effects of land-use change, climate variability, and groundwater withdrawals on surface and subsurface flow for watersheds.
