Land slide safety factor maps are generated for five cases, including three steady state conditions assuming either completely dry soils, half saturated soils, or fully saturated soils, and two quasi-dynamic conditions, i.e. soil wetness resulting from storm events with, respectively a 2 or 25-year return period. For the quasi-dynamic cases, two methods are used, one based on accumulation of groundwater flow from upstream areas, and the other on accumulation of soil water from direct infiltration.

The methodology delineates areas most prone to shallow land sliding in function of readily available data as topography, land-use and soil types. For the study area only 29% of the sPart of the JOL ProjectSupported by INASPNepal Journals OnLine (NepJOL) is a service to provide access to Nepalese published research, and increase worldwide knowledge of indigenous scholarship.

Landslides are the most common natural hazards in Nepal, where about 83% of the area are in the mountainous and hilly regions. In this study, a slope stability analysis on a regional scale is presented for a area of 347 km 2 of Dhading district, Nepal. A physically based slope stability model coupled to a simplified groundwater flow model is used to estimate soil wetness index, and factor of safety maps are produced for three steady state scenarios (completely dry, half-saturated, and completely saturated soils) and one quasi-dynamic scenario (soil wetness resulting from extreme daily raiJavaScript is disabled on your browser.

An analysis of slope stability using Geographic Information System (GIS) is presented in this paper. The methodology is based on the calculation of the safety factor in 2D and 3D using ArcGis. Results shows that the safety factors obtained in 3D are always higher than those obtain.
