Steep slope and toe erosion by river flooding and road construction activity led to development of pore pressure and reduction in shear strength due to water percolation in rainy season has added to the process of 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)
Risk of road and river blockade. During rains the blockade
UK/Pith/ Munsyari- Jauljibi/LS/0025
State Highway
Regarding of slope to mild angle with slopes and bench development. Stepped retaining wall with weep holes, covering the slope with geo-grid and flood protection wall all along the affected area.
Toe erosion in soil/debris due to river flooding, gully erosion by surface water during rains. Also development of pore water pressure and reduction in shear strength of the material due to water percolation in rainy season has added to the process.
