Contiunuous rainfall causing built up of pore pressure, river flooding leading to toe erosion caused this landslide

An interim report on Preliminary slope stability assessment of recent disaster affected areas of Pithoragarh District, Uttarakhand by A Bishwapriya, Suptg. Geologist, M V Dhakate and P K Gajbaiye, Sr Geologist, M IV, NR,Dehradun (LHZ/NR/UPUK/2013/056)

State Highway
Dredging of the river, flood protection walls, suitably designed retaining structures, nala training. Development of the slopes and benches in slide zone to curb the movement and reduce the angle.
Presence of loose and unconsolidated material, flooding of the river with high current, development of the pore pressure and reduction of the shear strength of the material due to saturation by water percolation, gully erosion and toe erosion in soil.
