UNSAT1 is a research model based on a generalized Hermetian finite element formulation for simulation of onedimensional flow in the unsaturated zone. This historic research code may be used to simulate moisture movement non-homogeneous soils with both abrupt layering and smoothly changing soil characteristics. The model is especially suited for wet soils and the change from fully saturated to unsaturated conditions. In dry soils, some oscillations may occur during infiltration simulation.
The program is distributed on a DOS-formatted diskette containing source code, executable image, and example data sets, and includes the user's manual.
