详细介绍了全世界对潮汐可再生能源项目日益增长的兴趣，包括潮流装置和潮差结构（即拦河坝和泻湖），但本章的主要重点是潮差可再生能源结构。在调查这种潮汐能计划的水文环境影响，无论是区域和远场效应，二维数值模型已被完善，以预测水动力的影响，包括尾流效应和洪水风险和危害的影响，并在保守和非保守溶质的浓度分布的变化，主要包括盐度，浊度，粪便指示生物，磷和氮的水平。该模型已被应用到一些关键的网站，特别是在塞文河口，英国，其中有第二个最高的潮差。本文考虑和报告的关键方案包括：（i）一系列泻湖沿着北威尔士海岸和（ii）横跨塞文河口的拦河坝。主要结论如下：（i）双向发电为尽可能保持该区域的现有条件提供了最佳选择，（ii）边界条件需要从大陆架产生，（iii）动量守恒对于涡轮机表示至关重要，（iv）泻湖相互作用，降低了效率，（v）涡轮机分布的设计对于最佳效率和最小环境变化至关重要。

Details are given of the growing worldwide interest in tidal renewable energy projects, including tidal stream devices and tidal range structures (i.e. barrages and lagoons), but the main emphasis in this chapter is on tidal range renewable energy structures. In investigating the hydro-environmental impacts of such tidal energy schemes, both for regional and far field effects, a 2D numerical model has been refined to predict the hydrodynamic impacts, including wake effects and flood risk and hazard impacts, and changes in the concentration distribution of conservative and nonconservative solutes, including primarily salinity, turbidity, fecal indicator organisms, and phosphorous and nitrogen levels. The model has been applied to a number of key sites and particularly in the Severn Estuary, UK, which has the second highest tidal range worldwide. The key schemes considered and reported herein include: (i) a series of lagoons along the North Wales coast and (ii) a barrage across the mouth of the Severn Estuary. The main findings are that: (i) two-way generation offers the best options for maintaining the current conditions in the region as closely as possible, (ii) boundary conditions need to be generated from the Continental Shelf, (iii) momentum conservation is crucial for turbine representation, (iv)lagoons interact with one another, reducing efficiency, (v) the design of turbine distribution is critical for optimum efficiency and minimal environmental change.
