“…Agricultural diffuse source pollution, such as erosion of cropland and the unreasonable application of agrochemicals to cropland, should be controlled and diminished firstly by land use planning and best management practices. Maintaining the natural geomorphologic features, especially the meandering pattern of the river is also compulsory for the good ecological condition of the river, and it is a key factor in preserving the self cleansing capacity of the river [23]. …”

Although it is not possible to completely eliminate flooding in an era of climate change and intensification of extreme weather events, effective flood prevention and management in river floodplains may make a significant contribution. The land use characteristics of a catchment and river valley determine, to a great extent, the functioning of a river floodplain, as well as the quantity and size of the flood pulses in the river. The paper is focused on the role played by ecohydrology in flood risk management and water quality. From the ecohydrological perspective, river floodplains are extremely important and capacious ecosystems which, being periodically flooded, absorb flood and pollutant peaks and may minimise the danger of flooding. Increased natural water retention capacity in floodplain areas and the whole basin in the face of progressive climate change is possible through three routes: the modelling of the hydrological budget of the catchment towards the sustainable ecohydrological management of floodplains, the optimal use of existing hydrotechnical infrastructure and the implementation of ecohydrological biotechnologies. Furthermore, with such a holistic perspective, the role of river floodplains is one that also enhances the resilience of the river basin against climate and anthropogenic change, as well as increasing flood safety, improving water quality and increasing its ecosystem services for society.

“…The prevention of eutrophication processes should be based first and foremost on understanding nutrient migration and transfer in a catchment and then on sustainable water management to local, regional, and cross-border scales [4].…”

“…Untreated or insufficiently treated wastewater has been the source of surface water pollution for many years on all inhabited continents, and nutrients included in them affect intensification of rivers, reservoirs, and the sea's eutrophication process [1][2][3][4][5][6][7]. In Europe, the Water Framework Directive (WFD) and the necessity to achieve good quality water by the EU states has necessitated modernisation of many wastewater treatment plants (WWTPs) with insufficient technology and construction of modern efficient WWTPs.…”

The aim of this study was to determine the change of water quality in the Trzemna River after modernisation of the wastewater treatment plant (WWTP) in Gołuchów and wastewater effluent diversion (WED) to the Prosna River in 2008. Data was acquired from the State Environmental Monitoring database for the period before and after changing the location of discharge from the treatment plant. The before-after (BA) and before-after-control-impact (BACI) analyses were used to determine the effectiveness of applied solutions. The BA study covered 12 physicochemical parameters and showed improvement of water quality in terms of phosphorous compounds, EC, ammonium nitrogen, TKN, TN, and BOD 5 . Lack of statistically significant differences for nitrates, pH, and TOC were noted. The BACI analysis was only applicable for six physicochemical parameters, and statistically significant differences were shown for TN, TKN, ammonium nitrogen, and TP. There were no differences in the case of nitrates and DO. After wastewater effluent diversion, a high concentration of nitrates in Trzemna water was still observed, with a statistically confirmed increasing trend. This is an effect of the negative impact of agricultural diffuse pollution. Modernisation of a WWTP and wastewater effluent diversion positively affected the quality of Trzemna water. The BA and BACI analyses in relation to statistical tests applied in hydrology can be successfully used to evaluate the impact of changes in the environment on water quality. In the case of BA design it was possible to analyse 12 parameters, whereas in BACI analysis it was only half of them. However, this method is recognised as more reliable and eliminates the impact of natural temporary variations.
