Trophic State and Water Quality in the Danube Floodplain Lake (Kopački Rit Nature Park, Croatia) in Relation to Hydrological Connectivity
The investigated floodplain lake is located in the marginal part of the Kopački Rit Nature Park, Croatia, a floodplain area of the Danube. In this chapter, we have assessed the influence of hydrological connectivity with the main channel on the trophic state and water quality in the Lake Sakadaš. The evaluation of trophic state combines a number of physical, chemical and biological parameters with the objective to select the relevant indicators for the floodplain lakes. The following environmental parameters have been considered: water temperature, nutrients, dissolved oxygen, water transparency, chlorophyll-a concentration, phytoplankton primary productivity, benthic and periphytic communities and laboratory experiments (nutrient enrichment bioassay). An integrative approach, which includes in situ research and laboratory experiments, indicated strong correlations of abiotic and biotic components with a hydrological regime. Also, during the biological monitoring, occurrence and spread of invasive species was noted as an indication of ecosystem disturbance (hydrological and/or anthropogenic). Therefore, our results contribute to the perception of importance of the hydrological connectivity (by inundation) on the eutrophication process in the investigated floodplain lake.
