A computational model has been used to explore characteristics of the barotropic tide around the Welsh coast in detail for the first time. Proper understanding of tidal characteristics is vital for the sustainable use of marine resources; particularly for industries such as marine energy extraction, aggregate mining, aquaculture, as well as regulators and agencies with responsibilities for the resource management and public safety. In shallow water areas, the influence of bathymetry and energy dissipation leads to the generation of higher harmonics that cause complex tidal phenomena. The Celtic and Irish seas, which enclose the Welsh coast (UK), are heavily industrialised shallow water seas with macro-to mega-tidal semi-diurnal tides. It is shown that tidal distortion is significant in the Bristol Channel (S. Wales) and in the large shallow estuaries of the N. Wales coast; for much of the west coast this is only significant in localised areas around headlands and islands. Tidal dominance switches from flood dominant in the south and north to ebb dominant on the west coast. Highly complex patterns of vorticity in the tidal residual flow are noted. All these factors mean that careful siting of industry and coastal management interventions is required to avoid disruption of the natural system.

对威尔士沿海水域潮汐的综合研究

首次使用计算模型详细探索威尔士海岸周围的正压潮汐特征。正确了解潮汐特征对于海洋资源的可持续利用至关重要；特别是对于海洋能源开采、骨料开采、水产养殖等行业，以及负责资源管理和公共安全的监管机构和机构。在浅水区，测深和能量耗散的影响导致产生高次谐波，从而引起复杂的潮汐现象。包围威尔士海岸（英国）的凯尔特海和爱尔兰海是高度工业化的浅水海，具有巨潮至巨潮的半日潮。结果表明，布里斯托尔海峡（南威尔士）和北威尔士海岸的大型浅水河口的潮汐畸变非常严重；对于西海岸的大部分地区来说，这种情况仅在岬角和岛屿周围的局部地区才显着。潮汐主导从南部和北部的洪水主导转向西海岸的退潮主导。注意到潮汐残余流中高度复杂的涡度模式。所有这些因素意味着需要仔细选择工业和沿海管理干预措施，以避免对自然系统的破坏。
