Implementation of the Water Framework Directive is a key starting point for integrated river basin management. Lack of sanitation in communities less then 2000 PE combined with agricultural activities, represent a special challenge for national water quality management. Sanitation for agglomerations smaller than 2000 PE and rural areas represent a big source of organic pollution not tackeled by EU legislation, and a threat for achieving good status for all water bodies and environmental objectives of the river basin. Moreover, some countries like Croatia and Slovenia comprise a large area of agglomerations smaller than 2000 PE. Proper management of thoose areas is crutial for preserving water resources as well as biodiversity. This paper will analyze some experiences related to management of rural areas using the DPSIR (Driving Forces - Pressures - State – Impact - Response) approach taking into account the principles of sustainability. Successful management of rural areas includes a variety of measures ranging from expensive sanitation of point and diffuse sources of pollution to low-cost solutions for pollution prevention of water bodies. The usage of the appropriate mathematical models, can assist in responding to environmental impact assessment and the optimizaton of the measures. In this paper will be presented the preliminary analysis of the mathematical models, as their applied and limiting possibilities, for water quality management of the river basin. In most cases those models need to be adapted or upgraded according to specific needs. The preliminary selection of the appropriate model for one river basin, that is Sutla basin, will be presented.
