Soil erosion is an inevitable phenomenon that additive erosion caused Soil degradation. Additive Soil erosion is one of the major obstacles to achieve the development of agriculture and natural resources. Thus, knowledge of the status and trends of soil erosion and sediment production in the watersheds is one of the most important tools for planning and decision-making. Models are the most popular tools for erosion and sediment processes. On the one hand, models as the best of decision support tools are important and on the one hand the entry of a large number of patterns, choice of best model or models can be challenging. Since a lot of models of erosion and sedimentation have been established in recent years, the need for an appropriate framework for choosing such models is essential. But unfortunately there is no such a framework. The purpose of this study was to identify and examine patterns of some common models used in the world was made. A designed flowchart regarding 1) the goal of study, 2) accessibility of data, 3) special scale of study and 4) implication of models was proposed to choose the best model. This flowchart implemented Minab Watershed in Hormozgan province. The results showed that none of the models were consistent with the objectives and requirements of the basin.
