Continental Portugal presents an extensive and diversified coastal zone which concentrates the main public and private infrastructures of the different economic sectors, as well as the main critical infrastructures. This area is also characterized by a high population density, being a differentiated territory in geophysical, biological and landscape terms. The wave regime is highly energetic, and storms are frequent. In the last decades, the coast of continental Portugal has been affected numerous times by overtopping and coastal flooding processes. Identifying the critical coastal typologies affected by flooding can contribute to a comprehensive flood risk management framework for the Portuguese coastal zones. Hence, a historical database of coastal flooding occurrences was created for the period 1980–2018 based on national and regional newspapers. For this period 650 occurrences were identified as well as 1708 impacts associated with them. In terms of impacts, the typologies associated with public areas, human impacts, the natural system, environmental degradation and buildings stand out. Results provide relevant temporal and spatial information about coastal historical flood occurrences related to extreme storm events and associated impacts, and contribute to the design of a risk framework.

葡萄牙大陆拥有广阔而多样化的沿海地区，集中了不同经济部门的主要公共和私人基础设施，以及主要的关键基础设施。该地区的另一个特点是人口密度高，是地球物理、生物和景观方面的差异化领土。波浪状态非常活跃，风暴频繁。在过去的几十年里，葡萄牙大陆的海岸多次受到溢流和沿海洪水过程的影响。确定受洪水影响的关键沿海类型有助于葡萄牙沿海地区的综合洪水风险管理框架。因此，根据国家和地区报纸，创建了 1980-2018 年期间沿海洪水事件的历史数据库。在此期间，确定了 650 次事件以及与之相关的 1708 次影响。在影响方面，与公共区域、人类影响、自然系统、环境退化和建筑物相关的类型学脱颖而出。结果提供了与极端风暴事件和相关影响相关的沿海历史洪水发生的相关时间和空间信息，并有助于风险框架的设计。
