Which is the largest estuary in India?
One of the major estuaries of the Ganges, the largest as well as longest river of Indian subcontinent, is the Hooghly estuary. It has a width of 3 to 12 km and is alive estuary supporting biodiversity and better known for its Hilsa fishery and the famous Sunderban mangroves.
What are the 4 types of estuaries?
Estuaries are typically classified by their existing geology or their geologic origins (in other words, how they were formed). The four major types of estuaries classified by their geology are drowned river valley, bar-built, tectonic, and fjords.
Where are most estuaries found?
Estuaries are found on the coast where fresh water like a river or a bay has access to the ocean. A good example of an estuary is a salt marsh that can be found close to the coast. Another example is when a river feeds directly into the ocean. The largest estuary in the United States is the Chesapeake Bay estuary.
What is the biggest estuary in America?
The largest estuary in North America, the Chesapeake Bay Watershed covers 64,000 square miles and includes more than 150 rivers and streams that drain into the Bay.
What animals live in estuaries?
Common animals include: shore and sea birds, fish, crabs, lobsters, clams, and other shellfish, marine worms, raccoons, opossums, skunks and lots of reptiles.
Which is the largest delta in India?
This Envisat image highlights the Ganges Delta, the world’s largest delta, in the south Asia area of Bangladesh (visible) and India. The delta plain, about 350-km wide along the Bay of Bengal, is formed by the confluence of the rivers Ganges, the Brahmaputra and Meghna.
Where are estuaries found in India?
Most of India’s major estuaries occur on the east coast. In contrast, the estuaries on the west coast are smaller (in environmental studies, deltas are considered as subsections of estuaries). Two typical examples of estuaries on the west coast are the Mandovi and Zuari estuaries.
Which river makes estuary in India?
Most of the major rivers of the peninsula such as the Mahanadi, the Godavari, the Krishna and the Kaveri flow eastwards and drain into the Bay of Bengal. These rivers make delta at their mouths. The Narmada, Sharavati, Periyar and Tapti are the only long rivers, which flow west and make estuaries.

Is Delta an estuary?
Estuary and Delta both are formed at the places where rivers meet the sea or drain their water into the sea. Though both are formed by the rivers, they are not similar.
|Types: coastal plain estuaries, tectonic estuaries, bar-built estuaries and fjord estuaries.
|Types: Fan-shaped, cuspate, bird’s foot.
What is a salt wedge?
Quick Reference. An intrusion of sea water into a tidal estuary in the form of a wedge along the bed of the estuary. The lighter fresh water from riverine sources overrides the denser salt water from marine sources unless mixing of the water masses is caused by estuarine topography.
Are estuaries saltwater or freshwater?
An estuary is a partially enclosed, coastal water body where freshwater from rivers and streams mixes with salt water from the ocean. Estuaries, and their surrounding lands, are places of transition from land to sea.
How are estuaries created?
This has occurred as sediments are washed down the rivers, or carried in from the sea by the tide, and dropped in the more tranquil conditions of the estuary. … All are a result of marine transgression, the first being drowned river valleys, which are referred to as spit enclosed or funnel-shaped estuaries.
What is a mix of salt and fresh water?
Brackish water, also sometimes termed brack water, is water occurring in a natural environment having more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) with fresh water together, as in estuaries, or it may occur in brackish fossil aquifers.
