Summary The bacterioplankton diversity in large rivers has thus far been under‐sampled despite the importance of streams and as components continental landscapes. Here, we present a comprehensive dataset detailing along midstream D anube River its tributaries. Using 16 S rRNA ‐gene amplicon sequencing, our analysis revealed that bacterial richness evenness gradually declined downriver both free‐living particle‐associated communities. These shifts were also supported by beta analysis, where...
Abstract. Hydrological observatories bear a lot of resemblance to the more traditional research catchment concept, but tend differ in providing long-term facilities that transcend lifetime individual projects, are strongly geared towards performing interdisciplinary research, and often designed as networks assist collaborative science. This paper illustrates how experimental monitoring set-up an observatory, 66 ha Open Air Laboratory (HOAL) Petzenkirchen, Lower Austria, has been established...

Changes in climatic conditions will directly affect the quality and quantity of water resources. Further on, they them indirectly through adaptation land use which ultimately influences diffuse nutrient emissions to rivers therefore potentially compliance with good ecological status according EU Water Framework Directive (WFD). We present an integrated impact modelling framework (IIMF) track quantify direct indirect pollution impacts along policy-economy-climate-agriculture-water interfaces....
Abstract. The main objective of the paper is to understand contributions uncertainty in low-flow projections resulting from hydrological model and climate projection uncertainty. Model quantified by different parameterisations a conceptual semi-distributed hydrologic (TUWmodel) using 11 functions three decades (1976–1986, 1987–1997, 1998–2008), which allows for disentangling effect function-related temporal stability parameters. Climate four future scenarios (ECHAM5-A1B, A2, B1 HADCM3-A1B)...
Cryptosporidium parvum is a pathogen causing gastrointestinal infections, occasionally leading to death in immunocompromised individuals. It can contaminate surface water and groundwater, consequently drinking supplies, through agricultural activities such as cattle dairy farming or the spreading of manure fertilizer. The importance removing C. by filtration great interest because its long-term persistence oocysts resistance chemical disinfection owing thick cell wall. This relevant for both...
Abstract Stream‐aquifer interactions are influenced significantly by riverbed clogging processes. Detailed field observations have been made in the “Freudenau reservoir” of Danube at Vienna. Different types clogged layers observed. Multi‐level‐piezometers below indicate that overall process consists several cycles a few weeks each initiated floods until stable state is reached. Minor flood events cause temporary increase leakage coefficient followed new decrease approaching original level...
