5 condition necessary for formation of river delta
A river delta is a land form that forms at the mouth of a river, where the river flows into an ocean, sea, estuary, lake, or reservoir.Deltas form from deposition of sediment carried by a river as the flow leaves its mouth. Over long periods, this deposition builds the characteristic geographic pattern of a river delta. A river delta is a land form that forms from deposition of sediment carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot carry away the supplied sediment. The following are conditions necessary for formation of river delta: The river must have large load. This will be possible if there is active erosion in the upper and middle stages. There should not be extensive deposition in the middle stage e.g. presence of lake in between or high evaporation rate (first). The river’s load must be deposit...
