CFITIM Model: Estimates parameters in several equilibrium and non-equilibrium transport models from solute breakthrough curves
 Entry ID: USDA_ARS_CFITIM

[ Update this Record ]

Summary
Abstract: Traditionally, a two-parameter partial differential equation has been used to describe the one-dimensional convective-dispersive equilibrium transport of chemicals in field soils. The parameters in this equation include the dispersion coefficient and a distribution coefficient, the latter accounting for interactions between the chemical and the solid phase of the soil. The resulting model is ... View entire text
