Iran also faces this problem due to its arid and semi-arid climate. Therefore, in addition to conserving available resources, efforts should be made to make the most of all precipitation. And prevented possible damage due to runoff in cities. In this article, we try to identify erosion-prone areas in Tehran with the help of previous experiences and using new sciences such as remote sensing science (GIS) and prevent soil erosion by operations such as banqueting or planting suitable plants. It also increases the infiltration of water into the soil to feed groundwater aquifers. Also, using this system, areas that produce a lot of runoff can be surveyed and these runoff can be stored and reused in reservoirs.
