A large wave flume named' Large Hydro-Geo Channel' was constructed in March 2000.The flume has a length of 184m, width of 3.5m and depth of 12m with a sandbed of 4m deep in addition to apistontype wave-maker generating 3.5m waves and a current generator with 20m3/s. Large-scale experiments can be conducted with amodel scale of 1/5 to 1/1, without major scale effbct problems. The wave flume is expected to contdbute to promote performance design of madtime structures by large-scale experiments including their failure processes: defbrmation of the structures, breakage of members, scouring and liquefaction of the fbundation. The wave flume should also contribute to reveal the mechanism of sea-seabed interactions.
