CHEMFLO - A Model to Simulate Water Movement and Chemical Transport in Unsaturated Soils
Entry ID: LSC_CHEMFLO


Summary
Abstract: CHEMFLO-2000 enables users to simulate water movement and chemical fate and transport in vadose zones. The software can be used to assist regulators, environmental managers, consultants, scientists, and students in understanding unsaturated flow and transport processes. Water movement and chemical transport are modeled using the Richards and the convection-dispersion equations, respectively. The equations are solved numerically using the finite differences approach.
