What are the conditions necessary for the formation of a delta?

Give the conditions necessary for the formation of a delta.

Answers

Maurice
(i) Large sediments are carried and deposited at the river mouth.

(ii) Low velocity of the river at the mouth.

(iii) High rate of deposition than the rate of removal of silt at the river mouth.

(iv) A shallow shore around the river mouth.

(v) Weak sea waves at the river mouth.

Ideal conditions for the formation of a delta

The river must have a larger load so it must originate from an area with high erosive power.

The course of the river should be free from obstacles which act as filters.

The river should be slow flowing on entering into the sea to prevent washing of sediments into the sea.

The river's load should be deposited faster than it can be removed by currents and tides.
