Seasonal variability of Crvena river water mineralization

Abstract

The mineralization of water and its content in Crvena River so far have not been studied. Water sampling was conducted from April 2008 - May 2009. Total mineralization is relatively low, which is consistent with the dominant lithological structure (Permian red sandstone). Dry residue contains Ca2+ ion, with the increased participation of SiO2. During the observational period it is clearly expressed seasonal effect. It is reflected not in the direct but the indirect impact. Based on the ratio of individual ions a model is determined for estimation of water flow at the confluence of the Crvena River in Nisava River. It could be applied to other drainage basins that have not been studied so far.

Mineralizacija voda i njena struktura u slivu Crvene reke do sada nije bila predmet istraživanja. Uzorkovanja voda vršena su u periodu april 2008.- maj 2009. godina. Ukupna mineralizacija je relativno niska, što je u skladu sa preovlađujućim petrološkim sastavom (permski crveni peščari). U strukturi suvog ostatka dominira Ca2+ jon, uz povećano učešće SiO2. U toku osmatranog perioda postoji jasno izražen sezonski uticaj. On se ogleda ne u njegovom direktnom, već u posrednom uticaju, preko vodnosti, aktivnosti vegetacije i aktiomiceta. Na osnovu odnosa pojedinih jona utvrđen je model procene proticaja na ušću Crvene reke u Nišavu. On bi se, sa izvesnim korekcijama, mogao primeniti i na drugim hidrološki neizučenim slivovima.
