| Abstract: | This paper deals with sedimentation and the resultant flushing of the run-of river power station
Bodendorf at the river Mur in Austria. The mean annual sedimentation rate for this reservoir is
approximately 35,000m³. To perform regular sediment flushings a monitoring programme was
developed to optimize the flushing operation in line with economical and ecological requirements.
Echo sounder surveys before and after the flushing, measurements of suspended sediment
concentration, bed load transport and hydraulic gauging were undertaken (1) to determine a
sediment balance of the flushing event, (2) to evaluate the effects of groins and an initial flushing
channel and (3) finally to get data for numerical modeling concerning hydraulics and sediments. The
ecological monitoring was performed by determining substrate conditions (freeze corer),
groundfauna (invertebrates) and fish ecological aspects. These data should document the flushing of
the reservoir Bodendorf and go towards improving the flushing management of the series of hydro
power plants respectively. This work was performed for the Interreg IIIb Project ALPRESERV
"Sustainable Sediment Management in Alpine Reservoirs" (www.alpreserv.org) |
| Description: | Paper presented at The Seventh International Conference on HydroScience and Engineering (ICHE) hosted by the College of Engineering at Drexel Univeristy on September 10-13, 2006 in Philadelphia, Pennsylvania. The conference theme was IT in the Field of HydroSciences. It included several mini-symposia that emphasized IT topics in HydroSciences and the yearly meeting of the metadata group of the International Oceanographic Data and Information Exchange organization. |
