Lunzer:::Rinnen - Experimental Flumes

The setting of the Lunzer:::Rinnen experimental flumes were established by Tom Battin in the mid 2000s and consists of six streamside flumes (40 m long, 0.4 m wide) that are continuously fed with raw streamwater from the Oberer Seebach in Lunz am See. Basic hydraulic and sedimentary parameters can be adjusted to the experimental needs; inorganic nutrients and DOM can be added to the flumes.

In the past, the Lunzer:::Rinnen were successfully used by the former Battin Lab to study biofilm development and succession and DOM uptake dynamics. Recent collaborative works by Jakob Schelker and Tom Battin included two major field experiments.

The first experiment was aiming to study the effects of soil additions on variations in optical properties of DOM and nutrient status. This work was performed by Jakob Schelker, Tom Battin and Lukas Thuile-Bistarelli together with the Zielinski lab from University of Oldenburg, Germany. Funding came from the FWF, ESF and Land Niederösterreich to Tom Battin.

The second experiment was performed by Jakob Schelker, Elisabet Ejarque Gonzáles and Tom Battin in collaboration with the University of Barcelona, Spain, namely Astrid Harjung, Andrea Butturini and Francesc Sabater. Funding for this work came from the EU (Interfaces project), as well as from the Austrian Academy of Sciences (EXCARB project).
