GSFLOW: coupled groundwater and surface-water flow model

GSFLOW is a coupled Groundwater and Surface-water FLOW model based on 
the integration of the USGS Precipitation-Runoff Modeling System (PRMS) 
and the USGS Modular Groundwater Flow Model (MODFLOW and MODFLOW-NWT). 
GSFLOW was developed to simulate coupled groundwater/surface-water flow 
in one or more watersheds by simultaneously simulating flow across the 
land surface, within subsurface saturated and unsaturated materials, 
and within streams and lakes. 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.

GSFLOW operates on a daily time step. In addition to the MODFLOW 
variable-length stress period used to specify changes in stress or 
boundary conditions, GSFLOW uses internal daily stress periods for 
adding recharge to the water table and calculating flows to streams and 
lakes.

GSFLOW can be used to evaluate the effects of such factors as land-use 
change, climate variability, and groundwater withdrawals on surface and 
subsurface flow for watersheds that range from a few square kilometers 
to several thousand square kilometers, and for time periods that range 
from months to several decades.
