Flood protection wall (crate wall construction is going on), river dredging on left side of the river, retaining wall in road section.
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
