1. Construction of lined hill side drainage with proper gradient. 2. Provision of gabion wall along the affected road stretch.
Increase pore water pressure in highly weathered slope forming material during heavy monsoon, reduced the shear strength of the SFM and thus initiated subsidence in the area.
