英国大量的河口不仅潮差高，而且潮汐流也很强，潮汐发电场可用于能源开采。本研究的目的是检查的影响，几何形状的通道上部署在河口潮汐发电场的影响。一个水动力模型（Mike21）已被用来模拟几个理想化的河口与尺寸的基础上的一组位置，适合在英国的潮汐能提取。在低和高水位与潮汐农场的最大变化已被确定为每种情况下，位于河口。文中还分析了河口内某一点的低潮和高潮时间的变化。值得注意的是，由于农场的原因，水位的最大变化范围从毫米量级到几分米，并且这些变化的位置在很大程度上取决于每个案例的几何形状。此外，低水位上升和高水位下降的影响通常比高水位上升和低水位下降的影响更明显。这将与潮间带的损失和洪水风险水平的降低有关。就低水位和高水位时间的变化而言，农场的影响在所有情况下都可以忽略不计。
A significant number of estuaries in the UK not only have a high tidal range but also exhibit strong tidal currents, where tidal farms could be used for energy extraction. The purpose of this study is to examine the influence that the geometry of the channel has on the impact of a tidal farm deployed in an estuary. A hydrodynamic model (Mike21) has been used to model several idealised estuaries with dimensions based on a group of locations suitable for tidal energy extraction in the UK. The maximum changes in low and high water levels with the tidal farm have been identified for each case and located within the estuary. The changes in the time for the low and high tides in a point inside the estuary have also been analysed. It is noted that the maximum changes in water levels due to the farm range from the order of mm to a few dm and the locations of these changes are strongly dependent on the geometry of each case. In addition, the effect is generally more noticeable in the increase of low water levels and the decrease of high water levels than vice-versa. This would be associated with the loss of intertidal areas and the reduction of flood risk levels. In terms of the changes in the time of low and high water levels, the effects of the farm are negligible in all cases.
