As a Consequence, the study of flooding fields involve the knowledge of certain meteorological and physiographic characteristic of the zone of study. The work shows the contribution of Remote Sensing, a Digital Terrain Model (DTM) hydrologically consistent and GIS in the fields of water rising, the cartography of fields and their integration in a coherent set. Each time, an important rain falls on a given region of the country, we expect floods. To apprehend these floods, it is important to understand the water cycle and its various interactions with the physical medium and to give bigger importance to the rain water draining. This attention has become obvious the (past) years with the advent of a number of rain simulation watershed models. The spatio-temporal characterisation of a watershed with a GIS with different resolutions, the suitability of a deterministic hydrologic model of a conceptual type, distributed and meshed and the height flow transformation will be traited. The visualisation of the affected zones by floods was reported on DTM. The application was made on a watershed of 60 km of “Oued El Moligoun” which is situated on the upwards the city of Arzew (ALGERIA).
