Soil erosion caused by heavy floods is a matter of concern as it leads to s problems like changes in river course, a sing loss of land, et c.

Flood  management  including  erosion  control  falls  within  the  purview  of  the  Sta management and anti - erosion schemes are formulated and implemented by concerned State Governmen per  their  priority.
