Abstract :
In this study, a water quality model of Haraz basin was used as an evaluative tool to estimate the spatial distribution of variables that are related to water quality and nutrient loads of the Haraz River. Previous studies performed in this river indicate that trout culture activity along the Haraz River have led to various changes in the water quality parameters. In the present work, the possible effects of two additional fish farms with a production capacity of 50 tons, located on the Haraz within 1 km distance from each other were evaluated in terms of their effects on the streams water quality. A water quality model was developed in order to investigate the spatial distribution of water quality variables. The model also used to estimate the dissolved oxygen (DO), biological oxygen demand (BOD5) and nutrients along the stream.
