  • No levees are generally made to guide the spread of water

2. Free Flooding.

  • This method is a somewhat improve method than wild or uncontrolled flooding method.
  • This method is mainly adopted where fields have not been properly prepared and field soil is so hard
  • That it will allow very small amount of water to be absorbed by top soil before flooding water gets evaporated.FREE FLOODING
  • allowed to flood or spread on whole of the field so as to give time to the soil to absorb sufficient amount of water.
