摘要

摘要: 海水入侵是困扰沿海地区经济社会发展的重大资源、环境问题，严重影响沿海地区地下水资源。定量模拟、预测和可视化管理是对海水入侵进行有效监测和机理分析的重要手段。基于前期海水入侵模拟的理论研究及方法，提出了海水入侵模拟及预测模型VFT3D，该模型综合考虑地表水-地下水对海水入侵的协同控制作用，能够模拟变密度地下水流及复杂反应性迁移，实现模拟海水入侵的完整水文循环过程。文章介绍了VFT3D模型，利用VFT3D模型模拟了一个海水入侵案例，并与SEAWAT模型模拟结果进行了对比分析。结果表明VFT3D 模型模拟水头与SEAWAT模型模拟结果相差不大，但SEAWAT模型无法模拟海水入侵中复杂的化学反应过程。VFT3D 模型模拟发现，水文地球化学过程（阳离子吸附交换作用）对阳离子（Na⁺、K⁺、Mg²⁺和Ca²⁺）运移产生明显影响，同时引起过渡带中离子组分浓度发生变化，对海水入侵过程产生较大影响。因此，考虑变密度和复杂反应过程，才能更加准确地描述海水入侵，从而有利于地下咸水治理工程的科学实施。

Abstract: Sea water intrusion is an important environmental issue that plagues the economic and social development in coastal areas. The implementation of quantitative simulation, prediction and visual management of sea water intrusion is a cost-effective means for monitoring and mechanism analysis of sea water intrusion, which can provide important theoretical and technical supports for the formulation of sea water intrusion control measures. VFT3D was proposed to model the sea water intrusion processes and predict the impacts on groundwater, which can comprehensively consider the effects of surface water and groundwater, simulate variable-density groundwater flow, and solve complex reactive migration problems. This article provides an introduction to the VFT3D model and presents an application of VFT3D to modeling seawater intrusion process. The simulated results are compared with those of the SEAWAT. The results show that the simulated water heads with VFT3D are close to the SEAWAT simulation results. The SEAWAT is unable to simulate complex chemical reactions during the sea water intrusion. The results indicate that geochemical processes (cation adsorption and exchange) have a significant effect on the movement of cations (Na⁺, K⁺, Mg²⁺ and Ca²⁺). Geochemical process leads to the concentration change in the transition zone, whose influence on the process of sea water intrusion can not be ignored. Therefore, the variable density and complex reaction process should be involved to more accurately describe the sea water intrusion, which can benefit the implementation of the underground saltwater remediation and management.
