Workshop Statement
Sediment bypass tunnels (SBT) are hydraulicstructures that gain worldwide importance as ameasure to counter reservoir sedimentation.
Sediments are bypassed around a dam to thetailwater reach reducing sediment aggradation in
the reservoir on the one hand and allowing forre-establishing sediment continuity on the other.
The latter is more and more aimed at from anecological point of view since river bed erosion
downstream of the dam is decelerated along withan increase of morphological and ecologicalvariability.
The 1st IWSBT in April 2015 hosted by the Laboratory of Hydraulics, Hydrology and Glaciology atETH Zurich, Switzerland, was a great success with
89 participants from 12 countries gathering toexchange and discuss latest research findings andexperiences.
We joyously invite you to participate at the 2ndIWSBT taking place in Kyoto, Japan, to further
discuss newest SBT-related topics. A 1.5 dayworkshop will be held at Kyoto University, UjiCampus, accompanied by a 2 day field trip toNagano Prefecture to visit the Miwa, Koshibu andMatsukawa sediment bypass tunnels.
The workshop encompasses keynotes, oralpresentations, poster sessions and sound discussions.
We look forward to seeing you in Kyoto!
