Abstract

Landslide occurs inevitably and naturally in many slopes due to sensitive formations, moisture, and
other factors. Taleghan watershed is prone to landslide due to the presence of huge Miocene marl
masses. After construction of Taleghan reservoir dam, moisture and ecological condition of the
region changed. In this paper, factors impacting upon landslide hazard (slope, aspect, hypsometry,
geology, land use, distance to road, distance to lake) were studied and their role and importance on
this phenomenon were verified in a large (maximum distance of 1500 meter from lake) and a small
(maximum distance of 450 meter from lake) spatial scale. Thus, GIS maps of the above mentioned
parameters were provided using satellite and aerial images and field activities. All maps were
crossed with a resolution of 100m*100m. It was found out that the distance to the lake didn’t
influence upon landslide in a large spatial scale but it falls effective as the distance to the lake
reduces. In fact lake has a local effect and mostly influences at maximum 200 meter distance.
