Debris flow occurred at Mulakuvalli, due to unscientific slope modification for cultivation.Reduction of strength on super saturation due to excess pore water pressure. Failure along weathered seam. Debris flow through natural nala path, which is a earli
On the right side of the debris flow situated the house of Pennama Sarojini, Thazhuvenchirayil, cut slope failure noticed behind the house. The debris material fell down on the kitchen side and damaged partially. So retaining structure should be founded
