Abstract

Bamdezh wetland with the geographical coordinates of   north longitude, east latitude and an area of 44 square Kilometers, is located in about 40 km northwest of Ahvaz and Shavur River is the main source of its supply. This wetland is not only a habitat and suitable food source for aquatic and migratory birds, but as well a significant resource of income for the locals. Today, with the arrival of various pollutants, construction of dam, water depth and wetland life has been threatened. In this study, in 29 sampling stations, the physical, chemical and biological water quality parameters of Bamdezh wetland, monthly for 6 months was collected. These parameters included temperature, fecal coliform, turbidity, NO3, PO4, pH, BOD, DO, TSS. Then, by determining the boundary of study area, using specialized software of Geographic Information System (ArcGIS9.3), database and processing of them, zoning maps and spatial distribution of pollutants using NSFWQI were prepared and analyzed. Among the notable results, the highest and lowest values of Water Quality Index were in June and medium water quality in all months (with some negligible part as exception in June) can be mentioned.
