Overtopping events in breakwaters under climate change scenarios [Dataset]. Zenodo

Reliable prediction of wave run-up/overtopping and structure damage is a key task in the design and safety assessment of coastal and harbor structures. Run-up/overtopping and damage must be below acceptable limits, both in extreme and in normal operating conditions, to guarantee the stability of the structure and the safety of people and assets on and behind the structure. The mean-sea-level rise caused by climate change and its effects on wave climate may increase the number and intensity of run-up/overtopping events and make the existing coastal/harbor structures more vulnerable to damage. Accurate estimates, through physical modelling, of the statistics of overtopping waves for a set of climate change conditions, are needed. The research project HYDRALAB+ (H2020-INFRAIA-2014-2015) gathers an advanced network of environmental hydraulic institutes in Europe, which provides access to a suite of environmental hydraulic facilities. They play a vital role in the development of climate change adaptation strategies, by allowing the direct testing of adaptation measures and by providing data for numerical model calibration and validation. The use of physical (scale) models allows the simulation of extreme events as they are now, and as they are projected to be under different climate change scenarios. The enclosed dataset refers to the experimental work developed at LNEC within HYDRALAB+ and considers 2D damage and overtopping tests for a rock armor slope, with four different approaches to represent storms. Data of free surface elevation, overtopping and damage is presented.可靠预测波浪爬升（wave run-up）与越浪（overtopping）现象及结构损伤，是海岸与港工结构设计及安全评估的核心任务。在极端工况与正常运行条件下，爬升、越浪现象与结构损伤均需控制在可接受范围内，以保障结构稳定性以及结构上及后方人员与资产的安全。气候变化引发的海平面上升及其对波浪气候的影响，可能增加爬升/越浪事件的发生频次与强度，使现有海岸及港工结构更易遭受损伤。 需通过物理模型试验，针对一系列气候变化情景精准估算越浪波浪的统计特征。HYDRALAB+（H2020-INFRAIA-2014-2015）研究项目汇聚了欧洲先进的环境水力研究机构网络，可调用一系列环境水力试验设施。该项目通过支持适应措施的直接试验，并为数值模型的率定与验证提供数据，在制定气候变化适应策略方面发挥关键作用。物理（缩尺）模型可用于模拟当前及不同气候变化情景下的极端波浪事件。 本附随数据集对应HYDRALAB+框架下在LNEC（Laboratório Nacional de Engenharia Civil，葡萄牙国家土木工程实验室）开展的试验研究，针对岩质抛石护坡开展了二维（2D）损伤与越浪试验，并采用四种不同方案表征风暴过程。数据集包含自由液面高程、越浪量及结构损伤相关数据。
