Description
Rui Bai and six colleagues optimised in 2026 riverbed dredging for a mixed pumped-storage power station in China, where hydropower, wind, and solar are combined. Such stations face a pumping funnel problem in the lower reservoir, a swirling dip that threatens reliable pumping, yet engineering fixes for it had barely been studied. Using the Lianghekou station as a case study, the team paired numerical modelling with physical experiments, choosing the best scheme by balancing pumping improvement against cost.
The chosen scheme was then verified in a large physical model of the whole lower reservoir. It widened the river cross-section by 15 to 23 percent, cut reverse flow by 30 to 42 percent, and shrank pumping funnel depth to 65 percent of its original value. Continuous pumping lengthened by 61 percent. The authors offer the numbers as a basis for design at Lianghekou, with lessons for other mixed pumped-storage projects.
