Surface-Water Routing (SWR) Process: A Program for Modeling Surface-Water Flow with the USGS Modular Groundwater Flow Model (MODFLOW)
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.
Conduit Flow Process (CFP): A Program to Simulate Turbulent or Laminar Groundwater Flow Conditions
Conduit Flow Process (CFP) allows simulation of laminar and turbulent flow within a standard MODFLOW layer and/or simulation of a hybrid model (one-dimensional pipe network coupled to MODFLOW).
