利用波浪浮标数据和一个44年（1958-2001）的后推数据集研究了阿斯图里亚斯（西班牙北部）的近海和近岸波浪能资源。在11个研究地点中，有7个发现海上平均波浪能和年波浪能值分别超过30千瓦/米和250兆瓦时/米。这一巨大资源的特点在于所涉及的海况。大部分能量由IV象限波提供，显著波高在2米至5米之间，能量周期在11秒至13秒之间。在分析了近海资源的基础上，采用数值模拟的方法研究了近海的波浪分布。利用波浪浮标数据验证了海岸波浪模型，并将其应用于风暴、冬季和夏季三个具有代表性的案例研究。近海波浪能集中区，作为潜在的波浪农场地点，被发现出现在维迪奥角西部和Peñas角半岛的西侧。这项调查中使用的方法可以作为其他地区波浪能评估的模型，特别是在近海和近岸资源都很重要的地方。
The offshore and inshore wave energy resource in Asturias (N Spain) is studied using wave buoy data and a hindcast dataset spanning 44 years (1958–2001). Offshore average wave power and annual wave energy values are found to exceed 30 kW/m and 250 MWh/m, respectively, at 7 of the 11 study sites. This substantial resource is characterised in terms of the sea states involved. Most of the energy is provided by IV quadrant waves with significant wave heights between 2 m and 5 m and energy periods between 11 s and 13 s. After analysing the offshore resource, numerical modelling is used to investigate the inshore wave patterns. A coastal wave model is validated with wave buoy data and applied to three case studies representative of storm, winter and summer conditions. Inshore wave energy concentration areas, of interest as prospective wave farm sites, are found to occur west of Cape Vidio and on the western side of the Cape Peñas peninsula. The methodology used in this investigation may serve as a model for wave energy assessments in other regions, especially where both the offshore and inshore resources are of consequence.
