Methods through which floods can be controlled.

  • Construction of dams to check the velocity and volume of rivers downstream.
  • Construction of dykes which restrict the outflow of rivers / raised river
  • Embankments.
  • Construct diversion channels to realign meanders and restrict flow of river / drain flooded areas.
