Shuikou Hydroelectric Project, currently under construction on the Minjiang River in the People's Republic of China is a concrete gravity dam having a maximum height of 101 m. The division plan selected for handling the river required a 3-stage scheme in which one of the major elements was the diversion wall separating the excavated diversion channel from the river. This diversion wall was designed and constructed as an RCC structure. The 646.6 m long RCC wall with a maximum height of nearly 50 m had to be designed on a minimum footprint along the edge of the river with the unique requirement of resisting water load from either side corresponding to the river flow at particular diversion stages. The construction of the diversion wall was successfully accomplished in September 1989 and the second stage of the diversion scheme commenced on schedule with diversion of the river to flow in the channel behind the wall.
