| Annotation | Chemismus vody byl v aluviálním systému horního toku Lužnice studován několika odlišnými, ale vzájemně se doplňujícími způsoby. Dlouhodobý monitoring 2-3 tůní od roku 1988, detailní studie vertikální distribuce a migrace fytoplanktonu, studium re-diverzifikace aluviálních vod po ústupu povodňové vlny, synoptická studie celkové diverzity tůní a mrtvých ramen a pod. Byly sledovány parametry: teplota, pH, rozpuštěný kyslík, saturace, alkalita, anorganické formy N, reaktivní P, vodivost a další.

| Description in English | Water chemistry of eutrophic alluvial waters in Lužnice floodplain has been studied using different methodological approaches within the space-time scale. Long term monitorong of seasonal course of selected localities, synoptic large-scale sampling, vertical profiles of floodplain pools and ungerground water studies have been completed to give a holistic picture of floodplain water chemistry and its diversity. Both external and internal factors determine the biological and chemical processes within the open-ecosystems of alluvial waters. Among external factors floodplain geodiversity play crucial role, determining morphology and location of pools and backwaters, their exposition to flooding and inflows of underground water. Terrestrial vegetation effects light exposition, i.e. amount and composition of phytoplankton and macrophytes and algae, photosynthesis and decomposition of leaf litter. Oxygen regime diverts the pools to aerobic and microaerobic types.
