The litho package on the affected slope constitutes conglomerate and sandstone that has undergone extensive weathering and is overlain by thin in-situ soil cover. During rainfall, oversaturation of this weak slope material resulted in temporary increase

1. Toe support for the affected slope through construction of strong RCC retaining wall with sufficient weep holes founded on sub stratum. 2. Construction and proper maintenance of concrete road side drain. Removal of trees from the crown area.
1.Extensive cut slope along Borkola-Cyan Nagar road 2. Weak slope forming material (Conglomerate and sandstone) 3. Over-saturation of weak slope forming material and increase in local pore water pressure during torrential rainfall.
