CHAIN 2D Model: Simulates the movement of water, heat and multiple solutes in two-dimensional variably-saturated porous media
 Entry ID: USDA_ARS_CHAIN_2D

[ Get Service ]
[ Update this Record ]

Summary
Abstract: CHAIN-2D is a computer program for simulating two-dimensional variably
saturated water flow, heat transport, and the movement of solutes involved in
sequential first-order decay reactions. The program numerically solves the
Richards' equation for saturated-unsaturated water flow and the
convection-dispersion equation for heat and solute transport. The flow equation
incorporates a sink term to ... View entire text
