Heavy rainfall for 3-4 days caused flooding of river and thus cutting of river banks accentuated with development of pore pressure in the unconsolidated loose pebbles, cobbles material on the slope adjacent to river bank

Dredging of the river and diverting to original course, Flood protection wall all along the affected area. No construction may be allowed on the river edge and at least 20m area from river edge to be kept as buffer zone.
The major geological causes for the incidence are presence of loose and unconsolidated material, flooding of the river with high current, development of the pore pressure and reduction of the shear strength of the material due to saturation by water perc
