Abstract

The preparation of LANDSLIDE susceptibility map is a major step in hazard management. Nowdays, such maps can be prepared by GIS-based qualitative and quantitative techniques useful to analyze the relationship between LANDSLIDEs and their influencing parameters. Study area in this paper is VAZ WATERSHED that is located in the northern Alborz and mazandaran province (south of Chamestan city).Here, LANDSLIDE susceptibility map using with statistic technique LOGISTIC REGRESSION to describe the relation between the presence or absence of LANDSLIDE (dependent variable) and a sets of independent parameters such as lithology and slope angle. LANDSLIDE distribution map was used to produce a dependent variable, which takes a value of 0 for the absence and 1 for the presence of LANDSLIDEs. Lithology, slope angle, aspect, altitude, landuse, distance to road and fault were taken as independent parameters. The effect of each parameter on LANDSLIDE occurrence was assessed from corresponding coefficient that appears in LOGISTIC REGRESSION function.The study area was classified into five categories of LANDSLIDE susceptibility: very low, low, medium, high and very high. The very high and high susceptibility zones makeup %20.3 of the total study area.
