OBERRHEIN - Phase I: Feasibility study & preliminary investigations, conception tracer study
Abstract
The sediment deficit in the Upper Rhine is primarily compensated by sediment augmentation. The input of bedload downstream of the Iffezheim barrage has a significant influence on the sediment balance and the riverbed development of the Upper Rhine. Previous studies with extraneous bedload showed that the added material travels on average between 2.2 and 5.4 kilometers per year, depending on the grain fraction, and is subject to sorting and mixing processes. More detailed statements are difficult with the methodology carried out so far, since no continuous information is available and not individual stones, but only the front (maximum dispersion, etc.) and the epicenter of the bedload tracers can be observed. Building on the knowledge gained through the luminophore studies and the incorporation of extraneous bedload, a tracer study will now be conducted using radiotelemetry. Active tracers with a "personal" ID will be used and their transport behavior will be documented over a period of several years. For this purpose it is necessary to adapt and improve a methodology for the tracing of tracers on the Rhine. In this first phase the methodology will be researched, first tests will be carried out on the Rhine and a tracer study will be designed.
