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.

室田和福原调查了北陆地区急流河流周围水工建筑物破损的例子。此外，为了研究其破坏机理，他们利用简单断面和复合断面的明渠进行了室内实验，阐明了动态流体力对丁坝和洪泛面决口的影响，给出了操作方向。桥野通过随机台风模型的降雨-风暴潮模拟，估计了与台风相关的强降雨和大风暴潮的并发特征，并提出了设计风暴的随机公式神田在兵库县的河流中使用超声波流量计进行了现场调查，测量流速波动的湍流特性，并研究了混凝土护岸趾部的侵蚀机制。佐藤构建了可变形岩石块模型，并将该模型应用于大坝地下室和岩石斜坡周围的地下水运动，以检查其运动对河流周围结构稳定性的影响。
