“Design Guideline for Rigid Frame Driftwood Reaper Joined to Existing Sabo Facilities (2020 Version)”
Background documents and introductory technical notes by the author Joji Shima himself, with most frequently asked questions (and technical advisories of the Center) are hereby made available FREE ONLINE.

①Introductory technical notes by Dr. Joji Shima, “sabo_topics” in the summer 2020
②Translated version of engineering article for the coming upgrading: Dr. Joji Shima and Ken’ichi Yasutomi, JECE, 2022, Vol75, No4
③FAQ for the current version of design guideline

Notice:
・Sabo Technical Research Institute of Sabo Technical Center has committed to keep engineering soundness and to make the best effective use of sabo facilities already in existence.
・Decades of engineering practice and accumulated experience technical consultation have been provided to the professionals nationally through publications and through seminars in addition to customized technical advisories.
・In addition to flagship technical documents such as “Design Handbook of Steel Sabo Structures”, recent major achievement is driftwood entrapment works to reap and curtail driftwood hazard in the densely populated downstream areas by entrapping and storing major parts upstream, on the sediment reservoir zones.
・The hands-on knowledge is for every engineer who is vehemently interested in this subject.
・Highly recommended for sediment and erosion control professionals, experts, and researchers nationally and similar sediment and driftwood issues in untamable river systems.
・Next upgrade is already within sight, therefore, related award-winning research paper published in Japanese Society of Erosion Control Engineering is downloadable here for your technical reference.
