On 15th August 2018, 2 debris flows happened near Aayodu, Poonchira along 2 nearby slopes covered by thick overburden material.  Increase in the pore water pressure and decrease in shear strength of the overburden material due to heavy rainfall coupled w
2 debris flows occurred along adjacent slopes. 50 m towards down slope of the debris flows, 4 houses, 1 road (Thanipadam- ayodu road) and 1 canal are situated.
Aayod debris flows
Aayod, Poonchira village.
Removal of unstable material from the source area and flow path, Easing of the slope by proper benching, construction of deflection wall and diversion channels along the flow path.
Increase in the pore water pressure and decrease in shear strength of the overburden material due to heavy rainfall coupled with heavy surface runoff and gully erosion along moderately sleep slope resulted in the slope failures in nearby locations.
