QUALITY PARAMETERS FOR SOMESUL MIC RIVER TRIBUTARIES IN CLUJ NAPOCA
Journal Title: Present Environment and Sustainable Development - Year 2013, Vol 7, Issue 2
Abstract
Quality parameters for Someşul Mic River tributaries in Cluj-Napoca. Water quality of Someşul Mic tributaries, which crosses Cluj town, is affected by natural and antrophic factors. Crossing inhabited areas, river channel harnessing, certain overflows modify water physical-chemical proprieties. Using some portable devices, we were able to track down seven parameters on eight tributaries and on Canalul Morii stream. The measurements were made between 2012 and 2013, in different temperature and rainfalls conditions. Some parameters (like pH, Redox potential) less vary, and some (temperature, ions, salinity, TDS) have more differences between the values from the two years. Also, there can be observed significant differences between the tributaries in the same measurement campaign (salinity, TDS). These differences reflect on the river bed, drainage basin conditions, and on antrophic influences. Some tributaries have harnessed river beds (Popii, Calvaria and Ţiganilor streams), some channels cross the town’s green areas (Popii, Ţiganilor, Becaş), and Zăpodie stream is influenced by waste deposit near the town. Nadăş, Chinteni and Gârbău streams come from outside the built area; on the other hand Popii, Ţiganilor and Becaş streams have their entire drainage basin inside the built area. A particular situation appears on Canalul Morii stream that diverts some of Someşul Mic waters upstream the town into the stream some kilometres more downstream.
