Simulation of one-dimensional water movement in the unsaturated zone by means of a first order Takagi-Sugeno model

A first order Takagi-Sugeno model is used as a basis for a groundwater model describing the water movement in the unsaturated zone. Fuzzy rules are used for estimating the water flux. Combining this fuzzy rule base with the continuity equation allows the modeling of water movement in the unsaturated zone.
