Optimization the Relationship Between Water Quality Index and Physical and Chemical Parameters of Water in Bamdezh Wetland, Iran

The main aim of current study was evaluation relationship between water quality index and physical, chemical and biological parameters of water for management wetland. Because of wetlands are valuable ecosystems that have economic, social, ecological and biological benefits and other values but degradation these natural systems in all round the world are increased. Bamdezh wetland is one of the important wetlands in Khuzestan province, Southwest of Iran. This wetland according to the definition of international Ramsar convention is riverine and palustrine wetland. Water quality of this wetland is fresh water and for purposes of temporal is permanent wetland. Bamdezh wetland has important role to control floodwater and over flow of Dez and Shavoor rivers. In addition, existence vegetation and different species animals show important of management planning for conservation this wetland. Because of importance of Bamdezh wetland, current study was optimization the relation between Water Quality Index (WQI) that has represented by USA National Sanitation Foundation and temperature, biochemical dissolve oxygen (BOD), NO sub(3), PO sub(4), pH, Turbidity, TSS, Conform, chemical dissolve oxygen (COD) and dissolve oxygen (DO). Results show that relation between water quality index and mention parameters are nonlinear.
