1. Rock filled with Gabions should be constructed along the side of the streams to avoid further toe erosion of the slope. 2. Removal of precariously hanging trees at the crown portion to shed the static load.
1. The affected slope comprises highly friable shale 2.Toe erosion by Naku nala 3.Over-saturation of weak slope forming material and increase in local pore water pressure due to rainfall.
