摘要：
The notion of diffuse pollution process in water bodies of different dimensions is formulated. An algorithm is given for calculating the average annual volume of the export of major biogenic elementsnitrogen and phosphorusfrom the watershed into ravine and river network of a small river. The article also gives the results of a series of computer simulations of the characteristics of spring overland runoff, soil erosion, and the export of biogenic elements from the watershed into the river network of the Istra R. under hypothetic changes in its landscape structure under the effect of urbanization and reforestation activities.
