Abstract

Our aim was to study the effects of short-term weather fluctuations on the quality of oxbows, based on the physico-chemical parameters of the water. The present study explored the effect of precipitation, temperature, and the water level of the main river on the quality of oxbows. We assessed the quality of four oxbows in the Upper Tisza region (north Hungary) over a two-year period. Water samples were collected in the summer in 2011 and 2012, and 12 physico-chemical parameters were investigated. We found positive correlations between the dissolved oxygen, water temperature, concentration of hydro carbonate, nitrate, pH, conductivity and the average temperature. Canonical discriminant analysis showed that the studied oxbows were similar in 2011 and 2012, based on physico-chemical parameters. Significant differences were found between the years, in terms of the water temperature, the content of suspended solids, and the concentrations of carbonate and chloride. Our results show that only short-term weather changes such as less precipitation and higher temperature cause the quality of oxbows to deteriorate. Our results demonstrated that the water quality of oxbows is influenced by the River Tisza, because the decrease in the water level of the Tisza was also responsible for the differences between the years, based on the physical-chemical parameters of the water.
