AbstractRecognition of the deteriorating conditions of rivers worldwide has called for increased efforts to improve the ecological quality of impacted river systems. This is particularly important in areas that have suffered from a significant impact of human pressure on the ecological status of water. Field studies were conducted in the Ruda River in an area that had undergone anthropogenic disturbances. The objectives of our survey were to test the biological metrics based on benthic macroinvertebrates at four study sites. Spring and autumn surveys of benthic invertebrates indicated that based on the BMWP and BMWP(PL) indices, water quality was higher in comparison with the value of Multimetric index at all of the sites that were studied. Our results revealed that the water quality was higher at the study sites that are located above the dam reservoir based on both the chemical and biological parameters. This study also indicated that both spring and autumn constitute appropriate periods for carrying out monitoring studies. The values of multimeric index indicated the same water quality (except for site 1) in both sampling periods. Anthropogenic transformations of a riverbed influence the flora and fauna and affect the ecological status of rivers.

AbstractThe study on a small lowland river was conducted in order to determine changes in water quality under external loading (inflow of treated wastewater, runoff from agricultural areas) and the location of a dam reservoir in its course. The 21 km long River Pogona (Greater Poland, Poland) is a small tributary of the Obra Canal in Kościan. In 2004, in its valley, the Jeżewo Reservoir, with an area of 78 ha, was utilized to supply the flow in the Obra Canal during the dry season and to irrigate agricultural areas. The river is also a receiver of treated sewage from the sewage treatment plant in Karolewo. The research, carried out in 2017 at six sampling stations in its course, showed that the discharge of treated wastewater resulted in an increase in conductivity, concentration of ammonium nitrogen, nitrites and total nitrogen in the waters of the River Pogona. On the other hand, the location of the Jeżewo Reservoir in its course contributed to an increase in water temperature, pH, dissolved oxygen, chlorophyll-a and nitrite concentration in the outflowing river. The results showed that the inflow of treated wastewater from the sewage treatment plant, surface runoff from the catchment area and the Jeżewo Reservoir formed in its course, influenced seasonal and spatial changes in the water quality of the River Pogona.

Physico-chemical characteristics of Parichha dam reservoir of Jhansi in Uttar Pradesh have been studied. The water temperature varied between 23.0 to 37.00C. The transparency, pH, chlorides and total hardness were in the range of 100 to 145 cm, 7.8 to 9.2, 42.0 to 59.17 mg/l and 100-197 mg/l respectively. The total alkalinity, dissolved oxygen and total dissolved solids ranged between 193 to 389, 5.2 to 8.6 and 90 to 310 mg/l respectively. The study revealed that the reservoir water is suitable for fisheries.
