Open Hydraulic Model Experiment for Consensus Development

Kagoshima Prefecture, Japan, 2007-2008
Prior to the construction of large-scale public works, it has become increasingly important to promote mutual understanding and to build consensus among stakeholders, including communities and authorities . In the case of river works, open model tests can provide a great support for that purpose.
The photo below shows an open hydraulic model experiment conducted for people living in a flood-damaged district along the Sendai River in Kagoshima prefecture, Japan. A series of tests shows the flooding situation, both in cases with and without a proposed new diversion channel at the site. Through these tests, the participants were able to directly understand the effectiveness of the diversion channel.and understand the kinds of topographical and scenery changes that would occur in their community. The communities and authorities found it easy to discuss the project from the same perspective.
These kinds of experiments are usually executed at a scale of around 1:50, but a 1:200 model was adopted in this case. The scale of the model should be decided from the viewpoint of how easily it will enable participants to understand the effect of the diversion work, as well as the supposed environmental changes in detail. CTI’s know-how and technology were fully applied to determine the model size in order to secure necessary preciseness in hydraulic phenomena and to enable participants to fully understand the project’s features.
