Sea-level rise (SLR) causes groundwater salinisation and water-table rise. The impacts these processes can have on water security, agricultural production and infrastructure are becoming widely recognised. However, some misconceptions relating to SLR impacts on groundwater have been observed among students, which may interfere with further learning and the application of science principles to everyday life. These misconceptions include the following: (1) water-table rise will equal SLR; (2) inland movement of the interface causes the rise in the water table under SLR; (3) seawater intrusion (SI) caused by SLR is small compared to SI caused by pumping. These misconceptions are explored with the aid of simple analytic solutions and a Jupyter Notebook. It is shown that: (1) water-table rise is only equal to SLR above the interface under flux-controlled inland boundary conditions; (2) water-table rise under SLR is not caused by SI, but rather is caused by the change in levels at the coastal boundary; (3) SI caused by SLR is a considerable risk, especially under the head-controlled conditions, which will become more common when land is drained to counter the effects of groundwater shoaling.

海平面上升 (SLR) 导致地下水盐化和地下水位上升。这些过程对水安全、农业生产和基础设施的影响正在得到广泛认可。然而，学生们对 SLR 对地下水的影响存在一些误解，这可能会干扰进一步的学习以及科学原理在日常生活中的应用。这些误解包括：（1）地下水位上升将等于SLR； (2)界面向内移动导致SLR下地下水位上升; (3) SLR引起的海水入侵(SI)比抽水引起的SI小。借助简单的分析解决方案和 Jupyter Notebook 来探索这些误解。结果表明：（1）在流量控制的内陆边界条件下，地下水位上升仅等于界面上方的SLR； (2) SLR下的地下水位上升不是由SI引起的，而是由沿海边界水位变化引起的； (3) SLR引起的SI是一个相当大的风险，特别是在水头控制条件下，当土地排水以抵消地下水浅滩的影响时，这种情况会变得更加常见。
