Sea-level rise (SLR) is influencing coastal groundwater by both elevating the water table and shifting salinity profiles landward, making the subsurface increasingly corrosive. Low-lying coastal municipalities worldwide (potentially 1,546, according to preliminary analysis) are vulnerable to an array of impacts spurred by these phenomena, which can occur decades before SLR-induced surface inundation. Damage is accumulating across a variety of infrastructure networks that extend partially and fully beneath the ground surface. Because the resulting damage is largely concealed and imperceptible, it is largely overlooked as part of infrastructure management and planning. Here, we provide an overview of SLR-influenced coastal groundwater and related processes that have the potential to damage societally critical infrastructure and mobilize urban contamination. In an effort to promote research efforts that can inform effective adaptation and management, we discuss various impacts to critical infrastructure and propose actions based on literature focused specifically on SLR-influenced coastal groundwater.
海平面上升 (SLR) 通过提高地下水位和向陆地移动盐度剖面来影响沿海地下水,使地下环境变得越来越具有腐蚀性。全世界低洼沿海城市(根据初步分析,可能有 1546 个)容易受到这些现象引发的一系列影响,这些影响可能在 SLR 引起的地表淹没几十年前就已经发生。各种基础设施网络在部分和完全位于地面以下的地方都在积累损坏。由于造成的损坏在很大程度上是隐蔽和难以察觉的,因此在基础设施管理和规划中很大程度上被忽视。在这里,我们概述了受海平面上升影响的沿海地下水以及相关的过程,这些过程有可能破坏对社会至关重要的基础设施并引发城市污染。为了促进有助于提供有效适应和管理的研究工作,我们讨论了对关键基础设施的各种影响,并根据专门针对受海平面上升影响的沿海地下水的文献提出了行动建议。
