1-, 2- and 3-dimensional modeling of water movement in the unsaturated soil matrix using a fuzzy approach

摘要: Modeling water movement in the unsaturated soil matrix is usually based on numerical solution of Richards equation. This approach requires much computational effort, therefore practical 2- or 3-dimensional applications are extremely rare. The purpose this paper to describe a computationally efficient and simple method. It transformation Darcy law fuzzy rule system. system combined with continuity equation yielding rule-based model for simulating flow. Basic definitions logic given concept flow outlined. presented performs well compared semi-analytical 2-dimensional, model. Furthermore has been incorporated into physically-based distributed, hydrological Model simulations different types situations show that especially suitable real-life applications.
