Geomorphologic Characteristics are base of study of natural resources in watershed basin. Because, these Characteristics are influenced by many factors such as climate, soil, hydrology, ecology, geology and so on. Doubtless, erosion features will develop with Geomorphologic Characteristics. In this research, effective factors on geomorphologic Characteristics and development of erosion features have analyzed using remote sensing data and GIS and with an integration method. In this way, boundary of basin was clipped using topography map in 1:50000 scales. Then, all layers such as geology, slope, and land use and land capability were digitized. An image of Land sat ETM+ taken in 2002 was also used to discretion of geomorphologic unit, Type and interpretation of erosion features.
The results showed that, Geomorphologic features in the basin separated to mountains, hills and alluvial deposit base on height, slope and morph metric Characteristics. Totally, eight Geomorphologic fancies are recognized. Stone mass with deposited cover from mountain unit with regular slope (1_1_1) have 74 ha (45% from whole area). Also, a lot of surface erosion has developed like white scattered spots and without vegetable or few vegetable. To add natural factors, human factors such as livelihood and sheep keeper can effect on developed erosion features.
