Abstract :
Abstract The Zyarat River which is the main source of surface water to supply water for city of Gorgan and surrounding areas has been confronted with potable water quality deterioration problem in the recent years. To recognize the strengths and weaknesses of water quality and opportunities and threats for its improvement the SWOT analysis has been conducted in this research. The results of this method have been used to identify the different zones of the Zyarat River with respect to pollutant potentials. To this end, five zones for pollutant potential (very low, low, moderate, high, and very high) have been considered. The results indicate that the maximum pollutant was measured in station 4 that is located in midsection of the Watershed in Zyarat Village. In contrast, the minimum pollutant value was measured in station 1, under the Zyarat waterfall in upper section of the watershed, and station 7, located in Gorgan city and lower section of the watershed, respectively. The most critical issue is inferior entry of sewage from rural and urban areas. The decision making process for reducing the pollutant potential of the Zyarat watershed can be facilitated by taking into consideration the results of this research given the time/budget constraints.
