Abstract

The SEMI-ARID MOUNTAINS due to climatical, hydrological and topographical properties are among the most vulnerable areas for the occurrence of LANDSLIDES. The deep stream bed and stream flow in long beds are main triggering factors for wall materials of valleys to slide. In the study region, as a semi-arid region, many LANDSLIDES were occurred because these LANDSLIDES events changing the hydrological properties of valleys and amount of load sediment. In this study, the role of many factors on occurrence of this event, as DRAINAGE DENSITY, relative' relief and property of surface's materials, by using geological and topographical maps, sampling of soil and field work are analyzed. The result of this study shows that the rate of detachments and LANDSLIDES depends to the rate of DRAINAGE DENSITY, specially depends to the DRAINAGE DENSITY of deep stream beds, rate of the changing of the ratio of Ds/Dd and also changing of R. When the rate of slope angle increases up to a certain level and on unconsolidated materials then the probability of the LANDSLIDES occurrence increases.
