摘　　要：The purpose of this research is to define initial parameters of Inaouene river and its catchment areas using radar data and satellite data. The Inaouene river is situated at the east of Sebou basin in North-East of Morocco. The study has been done by two dataset: 1) Shuttle Radar Topography Mission (SRTM) at a horizontal spatial resolution of 90 meters, and 2) ASTER (Advanced Spaceborn Thermal Emissionand and Reflection Radiometer) of GDEM version 2 at a horizontal spatial resolution of 30 meters, using ArcHydro model. Several raster and vector products of the Inaouene river and its catchment area have been defined at the end of the model. Moreover, final results of the ArcHydro model were compared with each other and with the reality. The result of this study can be used in baseline and advanced hydrology and geomorphology research on the catchment area. Besides of that, the result can define a spatial boundary of study on Inaouene River and its catchment area. Moreover, it would have support for decision-making on ground and surface water resource, distribution and management.The purpose of this research is to define initial parameters of Inaouene river and its catchment areas using radar data and satellite data.
