本文研究了滨海地下水系统中盐水入侵密度相关流的数值模拟。我们提出了一种方法来解决一个不变的有限元网格内的动态水位的移动边界问题的实现。该模型成功地针对无限制、密度相关基准的实验室实验数据进行了验证。经验证的软件应用于区域规模的研究领域，并充分校准的稳定状态的开发前的条件。瞬态质量输运情景模拟显示出良好的一致性与盐度测量满意地支持模型设置。
This paper deals with numerical modeling of density-dependent flow of saltwater intrusion in coastal groundwater systems. We present the implementation of an approach to solve a moving boundary problem for a dynamic water table within an invariant finite element mesh. The model is successfully validated against laboratory experiment data for an unconfined, density-dependent benchmark. The validated software is applied to a regional-scale study area and sufficiently calibrated for a steady state of pre-development conditions. Transient mass transport scenario simulations show good concordance with salinity measurements satisfyingly supporting the model setup.
