It has great guiding significance of studying the hydrodynamic distribution strong tide for Shenzhen River estuary management. The physical model of Shenzhen River was established to analyze the hydrodynamic distribution characteristics of beach and trough and the neap tide. The spring tide in dry season and typhoon "Hato" were selected as the boundary conditions in tidal optimal estuary. The results show that the tidal power of the main trough of the Shenzhen Estuary is obviously better than that of the middle beach, the flow velocity tends to increase from the downstream to Shenzhen River for the discharge section is narrower in upstream during rising tidal, the power of spring tide and ebb tide in dry season is basically the same, the power of spring tide in dry season is stronger than that of ebb tide, the estuary flow pattern is mostly affected by riverbed morphology during the low water level with a large area of open beach which made the south trough flow only. During the storm surge, the hydrodynamic force of the estuary is strong, the flow velocity of the middle beach is significantly greater than that of the dry season, the middle beach water is not flowing back to the trough for the high water level and the mangroves in the middle beach has a great influence on the flow pattern. According to the hydrodynamic characteristics and flood discharge requirements, the countermeasures for ecological beach consolidation and main channel widening in Shenzhen Estuary were put forward.

研究深圳河口在强潮作用下的水动力特性对深圳河口治理具有重要的指导意义,为此,采用物理模型模拟的方式,选取枯季大小潮和台风“天鸽”作为边界条件,分析了强潮作用下深圳河口的水动力特性。结果表明,深圳河口主槽涨落潮动力明显优于中滩,涨潮期间,从下游至南北槽分叉口过流断面束窄,流速呈增大趋势;枯水大、小潮涨潮动力基本相当,枯季大潮落潮动力强于枯季小潮;低水位期间,河口大面积露滩,几乎只有南槽过流,河床形态是影响河口流态的主导因素;风暴潮期间,河口整体水动力强,中滩流速明显大于枯季;由于风暴潮增水效应,河口水位高,滩面归槽流态不明显,中滩红树林对涨落潮流态影响大。根据水动力特性和行洪需求,提出了深圳河口生态固滩和主槽扩宽的治理对策。

研究深圳河口在强潮作用下的水动力特性对深圳河口治理具有重要的指导意义,为此,采用物理模型模拟的方式,选取枯季大小潮和台风“天鸽”作为边界条件,分析了强潮作用下深圳河口的水动力特性。结果表明,深圳河口主槽涨落潮动力明显优于中滩,涨潮期间,从下游至南北槽分叉口过流断面束窄,流速呈增大趋势;枯水大、小潮涨潮动力基本相当,枯季大潮落潮动力强于枯季小潮;低水位期间,河口大面积露滩,几乎只有南槽过流,河床形态是影响河口流态的主导因素;风暴潮期间,河口整体水动力强,中滩流速明显大于枯季;由于风暴潮增水效应,河口水位高,滩面归槽流态不明显,中滩红树林对涨落潮流态影响大。根据水动力特性和行洪需求,提出了深圳河口生态固滩和主槽扩宽的治理对策。

It has great guiding significance of studying the hydrodynamic distribution strong tide for Shenzhen River estuary management. The physical model of Shenzhen River was established to analyze the hydrodynamic distribution characteristics of beach and trough and the neap tide. The spring tide in dry season and typhoon "Hato" were selected as the boundary conditions in tidal optimal estuary. The results show that the tidal power of the main trough of the Shenzhen Estuary is obviously better than that of the middle beach, the flow velocity tends to increase from the downstream to Shenzhen River for the discharge section is narrower in upstream during rising tidal, the power of spring tide and ebb tide in dry season is basically the same, the power of spring tide in dry season is stronger than that of ebb tide, the estuary flow pattern is mostly affected by riverbed morphology during the low water level with a large area of open beach which made the south trough flow only. During the storm surge, the hydrodynamic force of the estuary is strong, the flow velocity of the middle beach is significantly greater than that of the dry season, the middle beach water is not flowing back to the trough for the high water level and the mangroves in the middle beach has a great influence on the flow pattern. According to the hydrodynamic characteristics and flood discharge requirements, the countermeasures for ecological beach consolidation and main channel widening in Shenzhen Estuary were put forward.
