Mahanadi River Delta in India is a basin of deposit that drains a large land mass of the Indian subcontinent into the Bay of Bengal. The alluvial valley is wide and relatively flat with a meandering river channel that changes its course.[1]
The Mahanadi River flows slowly for 900 kilometres (560 mi) and has an estimated drainage area of 132,100 square kilometres (51,000 sq mi).[2] It deposits more silt than almost any other river in the Indian subcontinent.[3]
The area of the drainage basin is 141,464 km2. The interior coastal plain has a relatively low elevation. The average elevation of the drainage basin is 426 m, with a maximum of 877 m and a minimum of 193 m.
