Influence of climate change and enlargement of irrigated soils on qualitative indicators of river water

It was determined that beginning from 1990s increase happened intemperature and amount of the precipitations significantly reduced. These climatechanges affected the quantitative indicators of the Kur water. The ion content of theriver water considerably rose in 2018 in comparison with 1952 and 1990s. This risewas more intensive towards the river mouth. In 1952 the ion sum in the GiragKasaman station was 419,0 mg/l, but in 1990 this figure was 608,3 mg/l, in 2018 itwas 620,5 mg/l. But in Banka near the river mouth a quantity of ions was 865,0 mg/l in 1952, 874,7 mg/l in 1990, but it was 888,1 mg/l in 2018. The climate alterationaffected mineralogical composition and amount of biogenic elements. A quantity ofminerals legally rose while approaching the river mouth. Especially this increasehas risen even further for 30 years.Change of the Kur water quality in this direction causes formation of some problemsin irrigation use. Tons of harmful salts enter every hectare of land. The undrainedand old unrepaired drained soil are salinized and create condition for degradation.
