It was planned to carry out excavation and treatment of the deep trough in Maozhou Estuary for the construction of the new town, which occupied the -3 m deep trough. The Pearl River estuary physical model was used to carry out tide hydrodynamics modeling test and suspended load model test to simulate the siltation distribution of the deep trough after one year of implementation. The test results show that the hydrodynamic characteristics and flow pattern of the study area have changed and the average siltation near the Maozhou Estuary reaching 0.75 m is more serious than that in downstream with 0.53 m, the -3 m deep trough remains connected with the whole widening rate is 1.57% and the thalweg is distributed along the Shenzhen shoreline with the minimum elevation is -3.40 m. The section morphology shows that the siltation on the right side is more serious than the left side and the upstream is more serious than the downstream. The treatment scheme changed the riverbed, the river regime will be significantly adjusted in the short term, but the -3 m deep trough can be maintained. The scheme is generally feasible.

空港新城建设侵占了茅洲河口-3 m深槽,拟开展主槽开挖治理工作。利用珠江河口整体物理模型开展潮流水动力试验和悬移质泥沙试验,研究治理方案实施1年后的主槽回淤分布。试验结果表明,研究水域水动力、流态发生变化,上游治理段接近茅洲河口,淤积较下游段明显,平均淤积达0.75 m,下游末端平均淤积0.53 m;淤积后,-3 m深槽保持贯通,全程扩宽率为1.57%,深泓线靠深圳侧分布,深泓沿程最小高程为-3.40 m;断面形态显示主槽右侧淤积大于左侧,上游淤积大于下游。主槽治理方案对局部河床进行了重塑,短期内河势将进行较明显的调整,但-3 m主槽得以维持,方案总体可行。

空港新城建设侵占了茅洲河口-3 m深槽,拟开展主槽开挖治理工作。利用珠江河口整体物理模型开展潮流水动力试验和悬移质泥沙试验,研究治理方案实施1年后的主槽回淤分布。试验结果表明,研究水域水动力、流态发生变化,上游治理段接近茅洲河口,淤积较下游段明显,平均淤积达0.75 m,下游末端平均淤积0.53 m;淤积后,-3 m深槽保持贯通,全程扩宽率为1.57%,深泓线靠深圳侧分布,深泓沿程最小高程为-3.40 m;断面形态显示主槽右侧淤积大于左侧,上游淤积大于下游。主槽治理方案对局部河床进行了重塑,短期内河势将进行较明显的调整,但-3 m主槽得以维持,方案总体可行。

It was planned to carry out excavation and treatment of the deep trough in Maozhou Estuary for the construction of the new town, which occupied the -3 m deep trough. The Pearl River estuary physical model was used to carry out tide hydrodynamics modeling test and suspended load model test to simulate the siltation distribution of the deep trough after one year of implementation. The test results show that the hydrodynamic characteristics and flow pattern of the study area have changed and the average siltation near the Maozhou Estuary reaching 0.75 m is more serious than that in downstream with 0.53 m, the -3 m deep trough remains connected with the whole widening rate is 1.57% and the thalweg is distributed along the Shenzhen shoreline with the minimum elevation is -3.40 m. The section morphology shows that the siltation on the right side is more serious than the left side and the upstream is more serious than the downstream. The treatment scheme changed the riverbed, the river regime will be significantly adjusted in the short term, but the -3 m deep trough can be maintained. The scheme is generally feasible.
