ABSTRACT
Wetlands are of high value in Earth life. ey have dierent, irreplaceable hydrological and ecological functions, such as stabilization of water supplies, ood damping, improvement of water quality, soil erosion control, recharge of groundwater, and carbon sequestration [51]. ese functions of wetlands could diminish the urbanization eects on aquatic resources
and biota. Wetlands are well known because they function like a kidney even though these ecological services are rarely assessed quantitatively and usually not in urban contexts. e failure of wetlands in their function as a kidney, by exceeding the capacity of a wetland to assimilate additional hydrologic, nutrient, or sediments, is usually not discussed and there seems to be an implicit assumption in the common understanding of wetlands that their capacity to assimilate is unlimited [27].
