Abstract Faced with persistent siltation of the perched Lower Yellow River, costly repeated dredging and declining sediment regulation efficiency of Xiaolangdi Reservoir, this report proposes an innovative regulation scheme relying on underwater steel-cable resonance platforms powered by shore-based electricity. Instead of passive dike construction and regular dredging, the design adopts zoned dynamic frequency adjustment and traveling-wave resonance to build a 620-kilometer bottom sediment transport channel from Taohuayu to Dongying Estuary. The river is split into four functional reaches, and flexible floating diversion weirs are deployed on the wandering Taohuayu-Gaocun floodplain to stabilize cross-section geometry and restrain fluctuation of natural water frequency, resolving the difficulty of full-channel synchronous resonance in open natural rivers. In dry seasons, vibratory hammers crush consolidated silt and oscillating baffles generate directional bottom flow to continuously carry suspended sediment seaward; during floods, ordered long waves reorganize flood turbulence and mitigate peak impact force. The full-line one-off construction cost is estimated at 16.4 billion RMB, with core equipment’s design service life exceeding 50 years, delivering prominent economic superiority versus decades of repeated dredging. Long-term operation can gradually deepen riverbed and transform the perched river into natural channel, while trapped silt forms new coastal land at the estuary. CFD simulation, flume tests and 2–3 km field pilot on the 206 km Taohuayu-Gaocun reach are suggested prior to full project rollout.
