Bamdezh wetland which is the combination of riverine and marsh wetland, occupying 44 (Km2) areas, is one the most important amongst the 22 existing wetlands in Iran and especially in Khuzestan Province. It controls the flood and overflow of Dez and Shavoor river and functions as a storage tank to control the overflow in winter. In summer it discharges water to Dez river. Because of the pollution, excessive upliftment of water by surrounding villages, draught and etc this wetland is shrinking very fast and becoming eutrophic. Shortage of stored water resulted into loss of habitats and biodiversity. Mathematical models have been developed to find out the healthy or positive relationship between the storage water (S) and wetland health index (WHI). On the basis of validity tested models, various methods for its restoration, reclamation and overall improvements have been suggested.
