Slope easing at the crown area. Construction of strong reinforced retaining wall/gabion wall at the toe of the slide founded on firm substratum. Construction of lined hillside drainage.
1. Weak slope forming material 2. Cutting of slope for road construction. 3. Incessant rainfall led to over-saturation of slope forming material results in reduction of shear strength due to rise in local pore water pressure.
