Analysis of the saltwater intrusion in the Changjiang estuary during the flood season in extreme drought year;

特枯水文年长江河口汛期盐水入侵观测分析

The main dynamic factors affecting the Changjiang River mouth saltwater intrusion are upstream runoff and outsea tide.

影响长江口盐水入侵的主要动力要素是上游径流和外海潮汐。

To exploit and utilize the freshwater resources of the Changjiang Estuary,studies on the pollutants of estuarine waters and the spatial and temporal variation of saltwater intrusion are very important.

长江口南支、南港、北港盐水来源主要有北支倒灌和外海盐水直接入侵两种形式 ,盐水入侵具有周日、半月、季节和年际变化规律 ,由于北支倒灌咸水团的影响 ,低盐度值往往出现在大潮期和涨憩附近。

The applications of the jet theory in the environmental protection,including the ocean disposal project for sewage,the jet dredging,the jet aeration for improving water quality,the cavitation for controlling eutrophication,and the bubble plumes preventing salt water intrusion,were comprehensively summarized and analyzed.

从污水海洋处置工程、射流冲沙清淤、射流曝气改善水质、空化射流治理湖泊富营养化以及气泡羽流阻止盐水入侵等方面对射流理论在水环境保护中的应用进行了综述和分析,并指出应从理论、试验与实际应用等各方面继续加强对射流的研究。

Nine automatic monitoring stations along the path of salt water intrusion were established around the Changjiang Estuary for automatic and real-time monitoring of the surface salinity and water temperature on a continuous basis.

根据盐水入侵路径,在长江口附近海域建立9个自动化监测站,对表层盐度、水温实施实时、连续的自动化监测。

Recent progress in study of concrete durability under simultaneous action of load and other factorsis reviewed, with a focus on influences of load on carbonation;salt corrosion; permeability of water and freeze-thaw cycles.
