沿海含水层是世界许多国家淡水供应的主要来源，特别是在干旱和半干旱地区。许多沿海地区也高度城市化，这一事实使得对淡水的需求更加迫切。沿海含水层对干扰高度敏感。对沿海含水层管理不当可能导致其作为淡水来源的破坏早于与海洋无关的其他含水层。原因是海水入侵的威胁。在许多沿海含水层中，海水入侵已成为限制地下水利用的主要因素之一。随着海水入侵的加剧，现有的抽水井，特别是靠近海岸的抽水井，会变得盐碱化，不得不废弃。此外，侵入的海水楔形上方的区域也失去了作为含水层自然补给来源的机会。尽管这一主题很重要，但到目前为止，还没有一本书将我们目前关于海水入侵的知识、海水入侵的产状、物理机制、化学、地球物理和地球化学技术的勘探、概念和数学建模、分析和数值求解方法、对抗海水入侵的工程措施、管理战略和从案例研究中获得的经验整合在一起。通过介绍这本关于咸水入侵的最新知识和经验的相当全面的卷，我们希望将这一知识体系传递给从事沿海淡水水资源可持续发展的地质学家、水文学家、水利工程师、水资源规划者、管理者和政府决策者。
Coastal aquifers serve as major sources for freshwater supply in many countries around the world, especially in arid and semi-arid zones. Many coastal areas are also heavily urbanized, a fact that makes the need for freshwater even more acute. Coastal aquifers are highly sensitive to disturbances. Inappropriate management of a coastal aquifer may lead to its destruction as a source for freshwater much earlier than other aquifers which are not connected to the sea. The reason is the threat of seawater intrusion. In many coastal aquifers, intrusion of seawater has become one of the major constraints imposed on groundwater utilization. As sea water intrusion progresses, existing pumping wells, especially those close to the coast, become saline and have to be abandoned. Also, the area above the intruding seawater wedge is lost as a source of natural replenishment to the aquifer. Despite the importance of this subject, so far there does not exist a book that integrates our present knowledge of seawater intrusion, its occurrences, physical mechanism, chemistry, exploration by geo physical and geochemical techniques, conceptual and mathematical modeling, analytical and numerical solution methods, engineering measures of combating seawater intrusion, management strategies, and experience learned from case studies. By presenting this fairly comprehensive volume on the state-of-the-art of knowledge and ex perience on saltwater intrusion, we hoped to transfer this body of knowledge to the geologists, hydrologists, hydraulic engineers, water resources planners, managers, and governmental policy makers, who are engaged in the sustainable development of coastal fresh ground water resources.
