the structure. Further, the absence of regular maintenance after the storms
exposed under layer has exposed the seawall towards its failure. On the
sea front, the toe failure exposes the armour stones to induce scour. Further, the design slope of front face would become steepened than the design
slope of 1:4. During non-monsoon, alongshore drift dominâtes in most of
the Coastal régions of Kérala. This would lead to steepening of the foreshore
in front of the seawalls and subséquent toe failure had been occurred.
