An area where the water table is at, near, or above the land surface long enough during the year to support adapted plant growth is called a wetland.
Step-by-step explanation:
Wetland is a private water body, which gets fed permanently or seasonally. Wetland is not purely a water body, because it allows some aquatic plants to grow which have adapted to its hydric soil. They have their place in almost every continent. They have some types too, namely swamp, marsh, bog, etc.
Mangrove forests are also a type of wetlands because the roots of the mangrove trees store a huge amount of water, which can be used for different purposes. And also, the wetland is at sea-level, which means it is near to the water table also. Its spatial flow is identical to that of the flow of groundwater.
