Abstract

Bank collapse width (BCW) is a considerably important index in the construction of water conservancy projects. In recent years, China has built a large number of hydropower stations. However, after reservoir impoundment for decades, the development of bank collapse width required clarification. Very few studies have provided feedback surveys or examined contrasting features of BCW. Through an analysis of BCW in a large reservoir in China, which was emptied completely owing to leakage, combined with a series of laboratory tests, this study describes the degree of influence of profile morphology on BCW. In addition, the BCW and bank collapse length of different planform morphology slopes, including convex plane-type, concave plane-type, and straight plane-type slopes, are discussed. This is a novel research, and it provides an important and reliable basis for the establishment of a BCW prediction model.
