The informatics support to the water resources integral protection from pollution

The paper gives a short methodological, display of the programme system for the support to the water resources integral protection from pollution in terms of the river basins, whose development is in progress at the Faculty of Civil Engineering and Architecture in Nis. The programme system represents an initial basis of the future expert system from water resources protection (regarding the river basin) and can be used for modeling and simulation of the waste waters processing facility functioning in the most diverse conditions during exploitation, defining of the most favourable management actions in the facility operative management phase, and for modeling and simulation of the water quality in the streams in the basin and consideration of the influences of the facilities and their effect not only at the efflux but downstream the whole basin.
