Description: Modelling of flow processes in individual parts of the hydrologic cycle are quite advanced, whereas coupled simulations of several hydrological processes within a river basin are more or less simplified. Various models exist which solve the Shallow Water Equations, but most of them have difficulties with computing the exact solution in areas where the bottom surface alters between dry and wet. The aim of this project is to develop a hydrodynamic-numerical model, which is able to simulate surface flow with drying and wetting areas and allow interaction with different hydrological processes. The two-dimensional Shallow Water Equations will be solved by means of the Finite Volume Method in an explicit formulation. Adaptive methods will be used to reproduce sharp fronts and steep bottom slopes. The model will be object-oriented designed and implemented in Java. One further work will deal with the interaction of surface flow and the unsaturated zone. Later development might deal with the simulation of surface flow in urban and natural areas, where drying and wetting or coupling of processes is an issue. It might also serve as a component of a physically based distributed catchment model.
