Abstract

In this paper temporal and spatial upstream to downstream Trend of water Quality were examined in Greater Karun basin. To assess the Trend of change 16 stations with a statistical period of 37 years (1353-1390) and with an overlaying spatial scatter within the basin were selected. In order to analyze the Trend, the MK test was performed which showed that the discharge has decreased throughout the basin, except for the southeastern part. Changes in z statistics for the Quality parameters were higher and at a significant level of 1% at Ahwaz and Shushtar stations located downstream of the basin. After analysis of the concentrations of anions and cations along with the type and facies of water it was determined that Ahwaz, Gotvand and Shushtar stations have chlorine, Sodic facies while in other stations the water exposed Bicarbonate and Calcic type. The Quality of drinking water in the stations has decreased from the upstream to the outlet of the Karun basin and the worst Quality are recorded in stations in Ahwaz, Gotvand and Shushtar, which are still within acceptable limits. In the Investigation of agricultural water Quality, it was also determined that the water Quality in Ahwaz, Gotvand and Shushtar stations lays in the C3S1 class. For other stations the class of water is C2S1. The results show that the water Quality of the Karun basin has deteriorated from the upstream to downstream.
