Kuranchery slide
Kuranchery-Nayarangadi road near Shornur-Kodungallur SH.
Easing of slope with proper benching, concrete retaining wall with weep holes and lined toe drain, a diversion channel is preferred to avoid oversaturation of slope in future heavy rain spells.
Infiltration of water during heavy rainfall increased pore water pressure and decreased shear strength of the thick overburden material with lithomarge clay which resulted in sliding.
