The main feature of this feature is its skewness. This surface is generally covered by soil and surface deposits. Since the soil is the most important element of the earth's biosphere, without which the life in the land will not be running and durable, preserving and protecting it is of particular importance (Badrifar, 2000). Sometimes humans, by cultivating slopes and plowing in the direction of slope, have caused vertical cuts in the slopes; plowing the slopes and building irrigation networks along the level curves and also digging the canals along the direction of the slopes have greatly contributed to the intensification of the process of destruction and erosion of the soil and the elimination of this valuable material. In this paper, the status and shape of erosion in different directions of the slopes and the effect of morphology and slope on erosion and its type have been studied in Natchi basin. In this research, in addition to field studies, various documents such as topographic maps, geology, vegetation, aerial photos and satellite imagery have been used as research tools.
