Abstract
General aspects of regional modelling of environmental impacts of non-point sources of pollution are discussed. Models range from simple budget to very complex structural models. In groundwater pollution studies structural models are preferable. The choice of the model depends on the aim of the research, the scale of the research area and the availability of input data. The degree of process aggregation in the models increases (complexity decreases) when the research aim is less, when the availability of data decreases, and the spatial units become larger. Results of two regional studies are given, one dealing with nutrient pollution in a small river catchment and the other with effects of atmospheric acid deposition on a European scale.
