The affected slope is composed of weak overburden material, mostly weathered and fragmented rock overlain by thin sandy insitu soil. During precipitation, water infiltration increased the local pore water pressure, weight of overburden, and reduced the s

Past landslides on the same site had damaged large cultivated lands (valley portion) that exist just below the road bench.
Nkio–Prasadimdik slide No.6
Nkio–Prasadimdik road section.
1. Construction of strong reinforced retaining wall/gabion wall at the toe of the slide founded on firm substratum.
2. Dressing of slope and removal of depleted material from the road.
3. Construction of lined hillside draiNGe. 

1. Weak slope forming material comprising of highly weathered sandstone and insitu soil.
2. Destabilization of slope due to illplanned slope cut.
3. Development of local hydrostatic pressure and reduction of strength on oversaturation of weak overburden
