气候变化引起的海平面上升（SLR）可能会影响河口水动力学和相关过程，包括潮汐能。在这项研究中，提出了一个层次的影响因素的未来河口潮汐能资源的基础上，他们的相关性SLR。这些因素包括主要因素（例如，潮汐棱镜、潮差、潮流、潮汐不对称性），次要因素（例如，沉积物输运），以及第三类因素（例如，河口形状/地形的变化）。鉴于河口的空间变异性，SLR对潮汐能资源影响的现有不确定性很高。SLR可能会导致潮差或潮流加强或减弱，这取决于河口的形状和边界条件（例如，是否存在堤坝和邻近的低洼地区）。到目前为止，当地的现场研究还没有导致一个总体评估的SLR对潮汐能资源的影响和比较研究，包括不同的区域和河口类型的建议，以解决现有的知识差距，并为决策者和利益攸关方提供见解。SLR对河口潮汐能资源的影响可能特别重要，因为SLR引起的变化可能会在可再生能源开发的运行寿命内改变可用资源（潮汐流装置为20-30年，潮汐拦河坝为120年）。在这方面，更广泛的环境影响以及技术经济评估难以预测，在作出与利用河口潮汐能计划潜力有关的长期管理决定时应谨慎行事。
Climate change induced sea level rise (SLR) is likely to impact estuarine hydrodynamics and associated processes, including tidal energy. In this study, a hierarchy of factors influencing the future of estuarine tidal energy resources is proposed based on their relevance to SLR. These include primary factors (e.g., tidal prism, tidal range, tidal current, tidal asymmetry), secondary factors (e.g., sediment transport), and tertiary factors (e.g., shifts in estuarine shape/landform). The existing uncertainty regarding SLR impacts on tidal energy resource is high, given the spatial variability of estuaries. SLR may cause tidal ranges or currents to strengthen or weaken, depending on estuarine shape and boundary conditions (e.g., presence or absence of levees and adjacent low-lying areas). To date, local site studies have not resulted in an overarching assessment of SLR effects on tidal energy resources and comparative studies encompassing different regions and estuary types are recommended in order to address the existing knowledge gaps and provide insights for policymakers and stakeholders. SLR implications to estuarine tidal energy resources may be particularly important as SLR-induced changes can alter the available resource within a renewable energy development's operational lifetime (∼20–30 years for tidal stream devices and ∼120 years for tidal barrages). In this regard, broader environmental impacts, as well as techno-economic assessments, are difficult to predict and long-term management decisions associated with harnessing the potential of tidal energy schemes within estuaries should be made with caution.
