Effect of the deep waterway project on the salinities in the north passage of the Changjiang Estuary

  • 摘要: 基于改进的三维数值模式FVCOM,聚焦于北槽盐度在工程一、二、三期建设过程中的变化情况.考虑径流、潮汐和风场的共同作用,数值模拟和定量分析在各工程阶段特征时刻和半月潮周期平均盐度分布特征.分析计算结果表明:一期工程后,等盐线显著下移.二期工程后,等盐线继续下移;1~5低盐水控制范围增大;中下段垂向混合变弱,部分时刻盐淡水混合类型从部分混合类型变成高度分层型.三期工程后,1~5低盐水控制范围继续增大;下段高盐水上溯,相比工程前有少许增加.
