Estuaries are partially enclosed coastal areas where freshwater from rivers mixes with saltwater from the sea. On India’s west coast, rivers like Narmada and Tapti descend swiftly from the Western Ghats and enter the Arabian Sea. Since the coast is narrow and steep, the rivers do not form deltas but instead widen near their mouths, creating estuaries. These are rich in biodiversity, support fisheries and serve as natural harbors. Estuaries are vital for ecosystems and local livelihoods.

Deltas are formed at river mouths where the river slows and deposits silt and sediment, creating a fan- or triangle-shaped landform. These deposits are rich in minerals, making the soil highly fertile. Rivers like Ganga, Godavari, Krishna and Mahanadi form vast deltas on India’s east coast. These deltas support intensive agriculture due to their nutrient-rich soil and ample water supply. They are also home to many species of birds and fish, making them ecologically and economically significant.
