Development and application of a non-point sources pollution model for hydrological processes and nutrient loadings in the Xitiaoxi catchment in South China

This dissertation describes the hydrology and non-point source pollution of the humid, subtropical Xitiaoxi catchment in the south-eastern China and comprises a hydrologic and nutrient dynamics simulation there. The study presents at first an interpretation of hydrological processes influenced by anthropological activities. Beyond that, it deals with nutrient cycles in both arable land with an intensive farming system and a natural forest dominated catchment
