Question

Write the conditions for delta formation ?

Answer

The ideal favourable conditions for the formation and growth of delta include :

1. There should be accelerated rate of erosion in the catchment area of concerned river . it in creases the amount of sediment supply .
2. The river should have long middle and lower course . it declines the speed of water flow at the moment of the river .
3. There should be suitable place in the form of shallow sea and lake shores at mouth of the river .
