Spatial evaluation and prospective risk of diffuse pollution by modeling on the catchment area of Bultiere

Abstract

In front of lawful uncertainties and the prospect for a heavy approach ZSCE on the sector of Bultière, study's initial objective was to explore methods to improve the phase of diagnosis, by as well as possible exploiting the various sources of available data. In spite of a conceptual modeling of the hydrological part, SWAT present undeniable advantages among which its capacity of multicriterion analysis with SIG and its approach mechanist of the agronomic part. Its exploitation accompanied several stages by reflection of the steering committee encouraged in approachs ZSCE.
