摘要
在一定条件下,水动力弥散作用较弱时,可应用突变界面模型来研究滨海含水层的海水入侵。本文应用了边界元数值模拟方法和狭缝槽模型,对影响界面运动的因素进行了分析,得出了界面变化的主要特征是:向内陆方向推进慢而向海洋方向消退快.有关结论可应用于地下水资源的管理和保护。
Under certain conditions, the effect of hydrodynamic dispersion is relatively weak, so that an abrupt interface approximation can be used in studying seawater intrusion in coastal aquifers. In this paper the boundary element method and a Hcle-Shaw model are used for numerical simulation. The influence factors on the interface movement are analyzed. A main feature of the nonstationary interface, slowly inlandward advance and rapidly seaward return, is introduced and can be applied to groundwater resources management and protection.
