Detailed explanation-1: -A simplified definition of wetland is “an area of land that is usually saturated with water". More precisely, wetlands are areas where “water covers the soil, or is present either at or near the surface of the soil all year or for varying periods of time during the year, including during the growing season".
Detailed explanation-2: -Low lying wet area means an area of a beneficial use site where the soils are saturated and where water tends to pond.
Detailed explanation-3: -A swamp is a wetland permanently saturated with water and dominated by trees. There are two main types of swamps: freshwater swamps and saltwater swamps. Freshwater swamps are common in inland areas. Saltwater swamps protect coasts from the open ocean.
Detailed explanation-4: -Wetlands are areas where water is the primary factor controlling the environment and the associated plant and animal life. They occur where the water table is at or near the surface of the land, or where the land is covered by water.
Detailed explanation-5: -Wetlands can generally be classified into five basic systems, namely: Lacustrine, Riverine, Palustrine, Marine and Estuarine (Frazier, 1996).
