NETFLO, 3-D Steady-State Ground-Water Flow in Heterogeneous Medium

Description of program or function: NETFLO simulates three-dimensional, ground-water flow in a heterogeneous medium idealized as a flow through an equivalent network of series and parallel flow members under steady-state flow conditions. The algorithm is based on the application of Darcy's law along each member and conservation of mass at each node. NETFLO determines the pressure at all nodes, and velocities and fluxes in all members, for all possible flow paths from a repository node to the discharge node, and the pertinent mean flow and transport characteristics along each path, for use as input to a one-dimensional nuclide transport program like GETOUT
