The objective assigned to this work, is the modeling of the water resources of the watershed of the Sebkha of Oran (Algeria) by the implementation of a hydrological data base able to write in an adequate way constituting elements of the physical environment.
The elaboration of a computerized data bank directed to the study of the functional unity which is watershed constitutes the quintessence of this work. In the concern to study the various factors acting on the functioning of the environment, it was possible to integrate a set of data resulting from various sources, such as the satellite images and the digital terrain models (DTM), within a geographic information system (GIS).
Keywords: Modeling, watershed, Sebkha, hydrological data base and GIS
