Murota and Fukuhara investigated the examples of breakages of hydraulic structures around rapid stream rivers in the Hokuriku district. In addition, to examine the mechanism of their damage, they carried out laboratory experiments using open channels with simple and compound cross-sections and clarified the effects of dynamic fluid force on the breaks of spur dikes and flood planes.To give the directions of operation of tide gates when typhoons strike, Hashino estimated the concurrent characteristics of both heavy rainfalls and large storm surges associated with typhoons through the rainfall-storm surge simulation with a stochastic typhoon model and proposed a stochastic formula of design storm pattern.Kanda carried out a field survey to measure turbulence properties of velocity fluctuation using a ultrasonic flowmeter in rivers in Hyogo Prefecture and investigated the mechanism of erosion at the toe of the concrete revetment.Sato constructed a defurmable rock block model and applied the model to groundwater motion around dam basements and rock slopes in order to examine the effects of its motion on the stability of the structures laid around rivers.

Murota和Fukuhara调查了Hokuriku地区快速溪流河流周围液压结构破裂的例子。此外，为了检查其伤害机制，他们使用带有简单和复合横截面的开放式渠道进行了实验室实验通过随机的台风模型，并提出了一个随机的设计风暴模式。Kanda进行了现场调查，以测量速度波动的湍流特性，使用河流中的超声流量计在Hyogo县的河流中进行了波动，并调查了跨层的侵蚀机制，并围绕着泥土构建的巨大的落基岩模型。斜坡以检查其运动对河流周围结构稳定性的影响。
