对挖泥工程可能造成的水质影响进行的定量模拟结果显示,在挖 泥工程进行期间,可能会在大范围内,令海床水层的悬浮沉积物浓度超出水质标准。这种情况可能会令受影响地区内的海豚猎物 资源的分布受到不良影响。 logisticshk.gov.hk | Quantitative modelling of the potential water quality impacts associated with dredging activities indicate the potential for large area exceedances of SS concentrations above water quality standards in the bed layer over the course of the dredging works, which may adversely affect the distribution of dolphin prey resources in the affected area. logisticshk.gov.hk |

接近底层的海浪及海流大多数 时候并不会再次冲动沉积物,但偶 尔 (大都是在发生暴风雨的时候) 也 会冲动沉积物使其在陆棚上流动, 甚至冲离陆棚。 pvsfish.org | Most of the time, near-bottom waves and currents do not resuspend sediment; however, episodically, primarily during storms, currents and waves resuspend and move sediment across and off the shelf. pvsfish.org |
文台定时收集大 气样本,包括大气飘尘、湿沉积物(降雨)、总沉积物(湿沉积物加㆖乾沉积物),以及气态碘。 weather.gov.hk | Atmospheric samples which are collected continuously in the ERMP include airborne particulate, wet deposition (precipitation), total deposition (wet plus dry deposition) and gaseous iodine. weather.gov.hk |
工程主要 用原地生化处理方法消减城门河河道沉积物发出的臭味,以及监测第 1 和第 2 阶段经生化处理後河床的沉积物和河水的质素。 devb.gov.hk | The works also comprise the monitoring of the sediment andwater quality after bioremediation treatment for both the Stage 1 and Stage [...] 2 works. devb.gov.hk |
下文 简单讨论了控制EA沉积物之演变和流布的生物、 化学及物理过程。 pvsfish.org | Below are brief discussions of thebiological,chemical, and physical processes that control the fate and transport of the EA sediment. pvsfish.org |

计算了所需挖走软性海洋沉积物(该区的挖掘深度通常为主水平基准以下 14 米),和保持主 干道隧道地下连续墙与海堤沉箱构件填石地基之间的间 隙,主干道隧道的外边与海堤盖顶线之间需要维持 31 米的 距离。 devb.gov.hk | 7.2.26 Typical sections through the seawall at the North Point shoreline are shown in the Minimum Reclamation Report, at Annex O. For a typical dredge level of –14mPD in this area, and maintaining the necessary clearance between the seawall foundation and the diaphragm wall of the Trunk Road tunnel, a distance of 31m needs to be maintained between the outer edge of the Trunk Road tunnel and the seawall copeline. devb.gov.hk |
