Abstract: The Wudongde Hydropower Station features narrow valley, steep bank slope, large flood discharge, high water head and deep riverbed covering. The layout of flood discharge building is subject to great limitations due to gullies developed at the dam site, giving rise to prominent hydraulic problems which pose daunting technical challenges to engineering design and construction. In this paper we expound the major research achievements in tackling the hydraulic problems via scale model test and numerical analysis. Such problems include: layout of the project, flood discharge and energy dissipation, flood discharge atomization, river diversion and closure, and multi-level water intake. The research achievements provide scientific and technological support for engineering design.
