风暴事件影响下黄河口潮滩沉积动力响应:认识与展望
Sediment dynamic response of tidal flats in the Yellow River Estuary under storm events:insights and prospects
摘要
Abstract
The Yellow River Delta,characterized by high sediment discharge,frequent human activities,and recurrent storm events,serves as a typical region for studying tidal flat changes under multiple stressors.This pa-per systematically synthesizes previous research on storm-induced sediment dynamic processes in the Yellow Riv-er Estuary's tidal flats and analyzes emerging challenges arising from the combined effects of storms and human activities.During storms,hydrodynamic characteristics,sediment transport,and erosion-deposition patterns exhib-it significant spatial heterogeneity across the delta.Wave effect dominates sediment resuspension on tidal flats near the current river estuary,while currents controlled by wind-driven flows and storm surges are prominent along the Diaokou and Laizhou Bay areas.Under prevailing northeasterly or northerly winds,onshore sediment transport and accretion trends are observed in the Diaokou and western current estuary regions,whereas offshore transport dominates along Laizhou Bay.Human interventions further modulate storm-driven sediment dynamic re-sponses:salt marsh vegetation,particularly Spartina alterniflora,enhances sediment deposition,yet its removal projects may exacerbate storm-induced erosion risks.The synergistic effect of pulsed sediment discharge during water-sediment regulation and onshore storm events can amplify tidal flat accretion efficiency.Against the back-drop of increasing storm frequency and poleward migration,future studies should prioritize investigating the com-bined effects of human interventions and storm events,as well as seasonal variations in storm impacts,to provide scientific support for ecological conservation and hazard mitigation in the tidal flats of the Yellow River Delta.关键词
