Lacustrine wetlands, around freshwater lakes and reservoirs. A wetland is a place where the land is covered by water, either salt, fresh or somewhere in between.

By contrast, the entire wetland is classified under the Circular 39 system as a Type 4 Wetland. Based on their origin, vegetation, nutrient status and thermal characteristics, they are classified into different types. They offer critical habitats for fish and wildlife, purify polluted waters, and check the destructive power of floods and storms. The water in a wetland is influenced by activities upstream, and the use of water in a wetland has an impact on the water quality and quantity downstream.

Each has its own characteristics. Certain specific wetland types in Africa such as dambos, riverine wetlands and freshwater marshes are increasingly being used for agriculture and human settlement with little or no consideration for integrated planning or studies of their ecological/ hydrological functions and values to society at large. 2.

Swamps are home to variety of animals like snakes, bobcat, alligators, beaver, large diversity of birds.

Constructed wetlands can be built with a much greater degree of control than natural systems, thus allowing the establishment of experimental treatment facilities with well-defined composition of substrate, type of vegetation, and flow pattern. The most common feature of all wetlands is that the water table (the groundwater level) is very near to the soil surface or shallow water covers the surface for at least part of the year. Wetlands are important for the following reasons: Filtration These special areas also serve as filters for water, removing pollutants and reducing sediment which otherwise flows into rivers and streams.

It covers an estimated 3 percent of India's land area. The association of man and wetlands is ancient, with the first signs of civilization originating in wetland habitats such as the flood plains of the Indus, the Nile Delta and the Fertile Crescent of the Tigris and Euphrates rivers. Wetland types represent the passage of the Indus River from the glaciers and high alpine lakes, through riverine and freshwater lakes to the Wetlands are natural reservoirs that hold water and attract a wide variety of plants and animals especially suited for wet environments.
