چکیده [English]

Soil is one of the most important natural resources of countries, which is under the influence of erosion, which leads to the reduction of land resources and many human and financial losses. Therefore, today and with the current trend, soil erosion has become a fundamental environmental problem, which in turn poses fundamental challenges to biological systems and planning systems at the level of communities, especially less developed local communities. On this basis and purpose, it is necessary to study soil erosion and sediment load, especially with regard to the influence of multiple environmental variables and with a systemic view and at the level of watersheds. With this approach, in this research, the evaluation and zoning of soil erosion risk at the level of Baneh basin has been done.The results show that the Baneh Basin is in the medium erosion class with erosion load and specific sediment with 1241 and 744 cubic meters per square kilometer per year, respectively. Examining the erosion severity zoning map also shows areas with low and medium erosion up to 68%. However, the effects of the high erosion zones are also quite obvious. The noteworthy point is the high potential of the Baneh basin to change the classes of erosion and sediment load, especially in the last few years due to the development of tourism in the Baneh market and the subsequent physical development of the city as well as the change of uses with the aim of creating recreational spaces and sometimes agricultural development. Therefore, it is necessary to have a perspective based on the basin's sustainability in creating development plans in it along with the process of education and promotion.
