A wetland is an ecosystem that depends on constant or recurrent, shallow inundation or saturation at or near the surface of the substrate. The minimum essential characteristics of a wetland are recurrent, sustained inundation or saturation at or near the surface and the presence of physical, chemical, and biological features reflective of recurrent, sustained inundation or saturation. Common diagnostic features of wetlands are hydricsoil and hydrophilic vegetation. These features will be present except where specific physicochemical, biotic or anthropogenic factors have removed them or prevented their development.
The three major factors that characterize wetland are water, physicochemical features and biota. Wetlands are neither aquatic nor terrestrial. It has some of the same features as deepwater systems, which include anoxic substrate, and some species of algae, vertebrates, and invertebrates. Most wetlands share terrestrial ecosystems. Wetland is found in terrestrial ecosystems such as lakes, rivers, and estuaries. Hydrology controls the biotic and biotic characteristics of wetlands, which are soil color, soil texture, and water. The biotic component of a wetland also can affect hydrology by increasing or decreasing water level or flow.
Three factors that explain the causes of variation among wetlands, First is geomorphic setting, which is floodplain, estuary fringe. Water source, and hydrodynamics. Setting is part of water product. Organic matter is when the soil with water slows decomposition, which causes wetland to carry organic matter. Wetlands are maintained by natural disturbances such as flood, fire, or herbivore and also Nutrient transformation which are nitrogen and phosphorus are carried into wetlands by precipitation, overbook flows.
