Parameters Chemflo Output Chemflo is an interactive software system for simulating one-dimensional water and chemical movement in unsaturated soils. Water movement is modeled using Richards' equation.
Chemical transport is modeled by means of the convection-dispersion equation.
These equations are solved numerically for one-dimensional flow and transport using finite differences. Results of Chemflo can be displayed in the form of graphs and tables. In nature this will seldom take place due to spatial variability in soil properties or boundary conditions. Although these processes have been modeled in two or three dimensions, the required soil properties are seldom known and the computational time is much greater. Chemflo also does not include source and sink terms so it cannot be used to simulate uptake of water by roots at different depths in the soil.
