Heavy rainfall and cloud brusting caused the river flooding with huge sediment load, which was followed by toe erosion. Also, the reduction in shear strength of slope material due to development of pore pressure was the other contributing factors to this

Flood protection wall, dredging of the river, re-grading of the terrace slope and provision of retaining structures
The major geological causes are presence of loose/unconsolidated material, toe erosion in soil/debris due to heavy flash flood and gully erosion. Also the development of pore water pressure and reduction of shear strength due to water percolation added t
