With a view to combating floods in the Far North of Cameroon, and updating the hydrological information of the hydrographic units (watershed) of the country, an assessment of the morphological characteristics of the Logone catchment area is necessary, as well as the evaluation of their influence on the flows. The methodological approach is based on the use of Geographic Information Systems for the processing of the Digital Terrain Model, in order to extract numerical data from the topography. The results show that the Logone catchment area at ERE has its sources in the highlands of Adamaoua at 1709m altitude and extends to ERE at 341m altitude. This basin covers an area of 66333, 431438 Km2 and has a perimeter of 1376,693437 Km. Its morphometric parameters make it possible to evaluate the weight of the geomorphology on the flow of surface water. Indeed, it is an elongated basin (Kc = 1.49, Rc = 0.43, F = 0.33), with a significant degree of erosion (old catchment), with a steep slope upstream (hypsometric curve). These morphometric characteristics increase the risk of flooding because they favor runoff at the expense of infiltration. This study contributes to filling the lack of hydrological information on the Logone watershed. The known morphometric parameters can be used as input data for hydrological models.
