Due to heavy down pour along a seasonal stream, cross-cutting the Athirapally-Chalakudy road, a rock cum debris flow occurred on 16.08.2018. The geo-scientific cause of the slide is due to increase in the pore water pressure and decrease in the shear str
Due to heavy discharge of material along the 1st order stream, the stream channel got widened.

Unstable debris material on the upslope as well as along the slide course needs to be removed. Culvert of suitable dimension need to be constructed at the road- nala junction.
Heavy down pour along a seasonal first order stream increased the pore water pressure and decreased the shear strength of the overburden material resulting in discharge of debris along the first order seasonal stream path. Cross cutting joints in weather
