Abstract

Abstract
River water quality is one of the important factors related to human health, living organisms and is strongly influenced by the prevailing conditions in the watershed. These activities are performed naturally or artificially with human intervention. In this regard, the present study assess the hydrological and edaphic indexes of the Ghareh Sou river. The trend of health data obtained from the software in each station was examined separately. According to the results obtained from the stations, three stations had a decreasing trend and two stations had an increasing trend. Nahar Khoran station had a decreasing trend at the level of 0.95 and the two stations, Pol Ordughah and Ghaz Mahale had a decreasing trend at the level of 0.99. The results of Tables show that Yasaghi station had the lowest level of health and Ghaz Mahale station had the highest health index score among the other stations. Ghaz Mahale station with a score of 0.86 has the highest health score among the studied stations and is the healthiest station in terms of hydrological health and Yasaghi station with a score of 0.72 has the lowest score among the stations. Health in Naharkhoran, Pol Ordughah and Ghaz Mahale stations had a decreasing trend at 99% , Yasaghi and Sade Kosar stations had an increasing trend. The Ghaz Mahale station has the highest downward slope.
