Sediment bypass tunnels (SBT) are hydraulic structures that gain worldwide importance as a measure to counter reservoir sedimentation. Sediments are bypassed around a dam to the tailwater reach reducing sediment aggradation in the reservoir on the one hand and allowing for re-establishing sediment continuity on the other. The latter is more and more aimed at from an ecological point of view since river bed erosion downstream of the dam is decelerated along with an increase of morphological and ecological variability.
The 1st IWSBT in April 2015 hosted by the Laboratory of Hydraulics, Hydrology and Glaciology at ETH Zurich, Switzerland, was a great success with 89 participants from 12 countries gathering to exchange and discuss latest research findings and experiences.
We joyously invite you to participate at the 2nd IWSBT taking place in Kyoto, Japan, to further discuss newest SBT-related topics. A 1.5 day workshop will be held at Kyoto University, Uji Campus, accompanied by a 2 day field trip to Nagano Prefecture to visit the Miwa, Koshibu and Matsukawa sediment bypass tunnels.

Topics

Upstream Aspects (Hydrology, Sediment Erosion & Inflow)

Tunnel (Hydraulics & Sediment Transport, Planning/Design, Tunnel & Inlet Works,

Invert Abrasion, Maintenance)

Downstream Aspects (Morphological Changes, Ecological Effects)

Operation (Monitoring & Instrumentation, Real-time Operation)

Keynote

Dr. George Annandale

Principal, George W. Annandale, Inc.

Dr. Annandale is a civil engineer with 42 years of experience specializing in water resources engineering. He is an expert in reservoir sedimentation management and is known for his expertise in scour of rock.

Title of keynote: Raising a Child and the Zen of Sediment Management

Dr. Chien-Hsin Lai

Director-General, Water Resources Agency, Director of Water Resources Agency, Ministry of Economic Affair , Taiwan (R.O.C.)

Dr. Chien-Hsin Lai was appointed as the Director-General of Water Resources Agency (WRA), Ministry of Economic Affairs since November 2016. Prior to that, he was the Deputy Director-General and the Chief Secretary of WRA, and the Director of Southern Region Water Resources Office. He was in charge of many important projects, including the emergency response plan for Cao Ling landslide dammed lake during Chi-Chi Earthquake, the trans-watershed diversion project of and sediment sluicing tunnel project of Tseng Wen Reservoir. To recognize his hard work, WRA awarded him the Outstanding Senior Award in 2006, and the Executive Yuan awarded him the Model Civil Servant Award in 2007.
