Conduit Flow Process for MODFLOW-2005
Entry ID: USGS_CFP
[ Get Service ]
[ Update this Record ]


Summary
Abstract: The conduit flow process for MODFLOW-2005 (CFP) has the ability to simulate turbulent or laminar ground-water flow conditions by: (1) coupling the traditional ground-water flow equation with formulations for a discrete network of cylindrical pipes (Mode 1, CFPM1), (2) inserting a high-conductivity flow layer that can switch between laminar and turbulent flow (Mode 2, CFPM2), or (3) simultaneously coupling a discrete pipe network while inserting a high-conductivity flow layer that can switch between laminar and turbulent flow (Mode 3, CFPM3). Conduit flow pipes (CFPM1) may represent dissolution or biological burrowing features in carbonate aquifers, voids in fractured rock, and/or lava tubes in basaltic aquifers and can be fully or partially saturated under laminar or turbulent flow conditions. Preferential flow layers (CFPM2) may represent: (1) a porous media where turbulent flow is suspected to occur under the observed hydraulic gradients; (2) a single secondary porosity subsurface feature, such as a well-defined laterally extensive underground cave; or (3) a horizontal preferential flow layer consisting of many interconnected voids. In this second case, the input data are effective parameters, such as a very high hydraulic conductivity, representing multiple features.
