“…In the spring, rainwater passes through the fractured rocks and reaches the clay layer, and the softening of the clay also leads to the movement of dangerous landslides [2]. The increase in the weight of the moving layer, the slope of the slope, and the washing of the banks by the river water cause the migration of landslides [1], [3].…”

Analyzing the landslide situation is one of the urgent scientific and practical problems in determining the conditions for carrying out construction works and protecting human life and economic sectors from danger. Landslides can cause economic damage, disable large structures and roads, destroy large areas of crops, and destroy villages and cities. In this study, for Akhangaran reservoir lands, techniques for assessing slope stability, ground mass stability during landslides, and landslide pressure were established for the scenario when soils exhibit both frictional and viscous qualities. These approaches took into consideration the internal factors impacting landslides. The obtained results are based on the development of activities that suppress the factors affecting the movement of landslides.

“…Emelyanova divided the size of dangerous landslides into "classes of landslides", describing the scale of the natural disaster [6]. Landslides with a 1-10 million m3 volume are usually frequent [3], [4]. One of the urgent issues is the development of methods for determining soil mass stability and landslide pressure [7], [8].…”

“…The life of the reservoir can also be reduced due to the increased sedimentation rate by the collapse of the slopes within a dam. Sudden collapse can even cause the formation of high waves in the reservoir beyond the crest of the dam (Gorbushina, 1997).…”

Slope failure is a widespread phenomenon in Lesser Himalaya owing to its fragile tectonic settings, rugged topography, high relief, abruptly varying gentle to steep slopes and peculiar climatic conditions. Road development and urban expansion have further deteriorated the slope conditions. National Highway 507, a part of the pilgrimage route to Yamunotri in Uttarakhand, is one such route, experiencing hostility from frequent slope failure episodes that are causing havoc for villagers and pilgrims. In the present study, the four most hazardous translational slide zones in the 22 km stretch from Judo to Kandi village in the Yamunotri pilgrimage route has been identified, for detailed geotechnical investigation and slope stability assessment applying different approaches. The rock masses of this region are inherently weak owing to their closeness to Aglar fault and other joints and fractures. Rock mass classification systems are used to assess the stability and for estimating strength parameters, viz. cohesion and angle of internal friction, essential for the factor of safety determination. They are slightly varying due to the relatively homogeneous grain size distribution and mineralogical composition of rock masses. Kinematic Analysis differentiated the type of failure as planar or wedge and, accordingly, factor of safety is determined by limit equilibrium approach. The factor of safety, computed strength parameters, discontinuity and slope properties, varies from 5.9 to 1.1 in dry conditions while it reduces below unity as the saturation upsurges. It depicts stable conditions in dry conditions but water penetration and saturation along the cracks and discontinuities during rainfall make them unstable. Close vicinity with fault, steep slope, presence of joints and weathered lithology are dominating factors initiating the instability in route with further aggravation by rainfall, road widening and urban expansion.
