DynaRev - Dynamic Coastal Protection: Resilience of Dynamic Revetments Under Sea Level Rise

This dataset contains processed data from the DynaRev experiments carried out in the Large Wave Flume (Grosser Wellenkanal, GWK) from 14-08-2017 to 29-09-2017 as a Transnational Access project within the EU funded project HYDRALAB+ (654110). The dataset provided under this DOI includes the post-processed data detailed in the article submitted to Scientific Data titled "High-resolution, prototype-scale laboratory measurements of nearshore wave processes and morphological evolution of a sandy beach with and without a dynamic cobble berm revetment" The overall aim of this project was to construct a prototype-scale beach and investigate the response of the beach to a rising sea level and storms with and without a cobble berm dynamic revetment structure (a gravel or shingle ridge placed around the wave runup limit). The response of two beach configurations was investigated under erosive wave conditions (Hs=0.8m, Tp=6.0s) and a total sea-level rise, SLR = 0.4 m: i) an unmodified sand beach with an initially plane slope of 1:15, and ii) a natural beach profile with a dynamic revetment installed at the location of the natural berm before imposing SLR. SLR was imposed in 4 steps of 0.1 m with an initial water depth of 4.5 m above the flume base. Each phase ran for a total of 58 hours, after which resilience testing under storm waves and accretive conditions was undertaken for a further 12 hours in each case. The changing profile of the sand beach and revetment was monitored throughout the experiments using a traditional profiler and a LiDAR array. Additional hydrodynamic measurements were obtained at the location of the offshore sandbar to investigate the process of bar formation and migration with SLR. The model set-up, experimental program and data structure are explained in the submitted Scientific Data paper. The data files are organised as detailed in "DynaRev_Data_Structure.doc".本数据集包含2017年8月14日至2017年9月29日期间，在欧盟资助项目HYDRALAB+（编号654110）框架下作为跨国访问项目开展的DynaRev实验的后处理数据，实验场地为大型波浪水槽（Grosser Wellenkanal，简称GWK）。本数据集通过当前DOI发布，其包含的后处理数据已在投稿至《科学数据》（Scientific Data）的论文中详述，该论文标题为《高分辨率原型尺度实验室测量：含与不含动态砾石滩肩护岸的砂质岸近岸波浪过程与地貌演化》。 本项目的整体目标为搭建原型尺度岸滩，探究配备与不配备砾石滩肩动态护岸结构（即布置于波浪爬高限界处的砾石/卵石脊）时，岸滩对海平面上升与风暴作用的响应。研究针对两种岸滩配置，在侵蚀性波浪条件（有效波高Hs=0.8m，谱峰周期Tp=6.0s）及总海平面上升SLR=0.4m的工况下开展：i）初始平面坡度为1:15的未改性砂质岸滩；ii）在施加海平面上升前于天然滩肩位置安装动态护岸的天然岸滩剖面。 海平面上升以4级0.1m的步长逐步施加，水槽基底以上初始水深为4.5m。每个实验阶段总时长为58小时，随后针对两种配置分别开展为期12小时的风暴波浪与淤积条件下的岸滩恢复性测试。 实验全程采用传统剖面仪与激光雷达（LiDAR）阵列，对砂质岸滩及护岸的剖面变化进行实时监测。此外在离岸沙坝位置开展了额外的水动力测量，以探究海平面上升过程中沙坝的形成与迁移过程。 模型搭建方案、实验流程与数据结构已在上述投稿至《科学数据》的论文中详细说明。数据文件的组织方式详见《DynaRev_Data_Structure.doc》。
