Background:
Reservoir sedimentation is a worldwide challenge that seems to accelerate in the last couple of decades with climate change. Amongst numerous sediment management strategies to mitigate this issue, Sediment Bypass Tunnels (SBTs) have proven to be an effective solution, especially for small- to medium-sized reservoirs. SBT design is generally case-specific. Recent laboratory experiments, field studies, as well as numerical investigations have enhanced the existing knowledge on SBT design criteria and the associated challenges, which are to be discussed to a broader audience.
Building upon the success of previous successful workshops on SBTs held in Switzerland (2015), Japan (2017), and Taiwan (2019), we are delighted to invite you to the 4th International Workshop on SBTs. The workshop will take place at the Technical University of Munich, Germany and will provide a platform to exchange knowledge and experience on reservoir sedimentation, sediment routing through SBTs, their designs, related geomorphological and ecological aspects. The main focus shall be on the recent advancements in planning and design, invert abrasion, operation strategies, experimental and field studies, and numerical modeling related to reservoir sedimentation and SBTs and on the technical excursion in the Alps.
