Abstract

In this paper Kashkan basin from upstream to downstream water quality changes were evaluated. First, the ‎process of long-term qualitative changes in two branches Kashkan (Khorramabad and Horod) was evaluated. ‎Mann-Kendall test was used to determine Routing data. For examination of water quality AqQA software ‎Schoeller diagram extracted and analyzed for each station. Information needed to assess water quality in terms ‎of agriculture was transferred to the diagram Will Cox and Classification of water was determined. At all ‎stations trend of discharge, negative and to further Water Quality Indicators the trend was positive. The results ‎showed that in both branch water quality parameters Decreased. Water quality changes after joining the two ‎branch Khorramabad and Herod At the station Poldokhtar was investigated‏.‏‎ At the station Poldokhtar Many ‎parameters were In a range between the value of them In two branches before joining But in some of them ‎also was violated this law and increased At the station Poldokhtar. Due to the reduction in flow rate and ‎increase of quality parameters, the basic premise was proven.‎
