摘要
感潮河段河口闸泵的建设对流域防洪潮具有一定的作用。以2017年台风"天鸽"对深圳茅洲河流域的影响为例,采用MIKE11水动力模型,模拟在茅洲河口建设闸泵对河口地区防洪潮的作用。结果表明,对比河口设闸和无闸工况,在设闸工况下,闸上内河水位比无闸工况降低2.50 m左右;在设闸且设泵工况下,闸上内河水位比无闸工况降低3.20 m左右。
Building sluice and pump at the estuary is effective in flood control. This paper investigated the effect of building sluice and pump at the estuary of Maozhou River by applying the MIKE11 hydraulic model in a case study during the typhoon Hato in 2017. The result indicates that the water level in upper approach of the sluice will be 2.50 m lower if the sluice is built. If the sluice and pump are built together,the water level in upper approach of the sluice will be 3.20 m lower.
