The economic growth that has been occurred in the world, especially in countries like Brazil, there was an increasingly intense search for areas occupied with agricultural, livestock and industrial activities. The occupation of these areas inappropiates is a leading cause of processes such as soil degradation, since, in general, the ability of the land is not studied before the process of allocation a use for them. Thus, this study aimed to investigate the land use in the watershed of Gramame river, upstream of the reservoir Gramame - Mamuaba, pointing conflicts, and generating information for planning by applying the methodology to determine the propensity to risk the soil loss and the definition of potential uses based on the calculation of roughness coefficient for hydrographic basins and the classification of the identified conflicts. The results indicate that the potential usage scenario of land obtained for the study area causes a greater soil loss from the land use currently found in the catchment area. It was also observed that the absence of conflicts or inadequacies was predominant in the study area was present in 47,13% of the area. The conflicts considered positives was classifieds in while 18,31% of the watershed. The situation where the use of the current soil is more appropriate than suggested according to the coefficient of roughness, featuring negative conflicts occurred only 18,31% of the total.
