The affected slope is lithologically weak with thick section of highly weathered sandstone. Due to choking of the lateral drain and culvert, water overtopped and flowed over the road eroding the already soaked soil due to rain that failed taking away wit

• Construction of lined hillside drains to prevent surface run – off entering into the slide zone.
