Abstract

In present research, LANDSLIDE HAZARD ZONATION of LATIAN DAM watershed area has been carried out using Analytic Hierarchy Process (AHP), VALUING AREA ACCUMULATION, FACTOR OVERLAY AND INFORMATION VALUE methods. In order to determine the most important factors affecting land sliding, different maps comprising slope, aspect, altitude, faults, drainage network, access roads, lithology, land use and friction angle maps were prepared digitally using aerial photos, maps, data and field investigation. Afterward affecting factors were evaluated using encountered old landslides. The results of evaluation show that lithology, the distance from fault, slope, dip direction, land use, the distance from road and stream are important effective factors on sliding in this area. These parameters were leaded to landslide zonation maps. These maps show that potentially high risk zones point of view landslides are located near the central and western boundaries of the reservoir which are needed special attention. Performance of four used classification methods were evaluated and compared by Indexes of Quality Sum (QS), Density Ratio (DR) and Precision of the Predicted (P). The evaluation results show that VALUING AREA ACCUMULATION and Factor overlay are precise methods for evaluating landslide potential in the study area respectively.
