尽管越来越复杂的数值模型和现场技术调查波浪引起的近岸沉积物运输和随之而来的海滩形态的反应，仍然有一个大规模的实验室实验，以解决这一研究课题的显着需求。在这里，我们描述了屏障动力学II实验（BARDEX II），其中包括放置一个近原型规模的桑迪屏障在荷兰的三角洲水槽的中间，并受到一系列的波浪，潮汐和水位条件的结构。实验的一个独特的方面是在屏障后面存在泻湖，这在天然屏障设置中经常发生，提供了一种方便的手段来实验性地操纵屏障内的地下水水文。BARDEX II的总体目标是收集一个大规模的数据集的能量波作用于一个桑迪海滩/障碍系统，以提高我们的定量理解和模拟能力的浅水沉积物输运过程中的内冲浪，冲，和过洗区。在本文中，我们介绍了BARDEX II和实验的详细描述，包括实验设计，仪器，测试程序和数据集，以及提出一些例子的形态和流体动力学数据集。我们还客观地反映了数据集的优点和缺点。这篇论文是《海岸工程》专刊的介绍，专刊介绍BARDEX II的结果。(C)2015 Elsevier B.

Despite the increased sophistication of numerical models and field techniques for investigating wave-induced nearshore sediment transport and ensuing beach morphological response, there remains a significant demand for large-scale laboratory experiments to address this research topic. Here, we describe the Barrier Dynamics II Experiment (BARDEX II), which involved placing a near prototype-scale sandy barrier in the middle of the Delta Flume in the Netherlands and subjecting the structure to a range of wave, tide, and water level conditions. A unique aspect of the experiment was the presence of a lagoon behind the barrier, as often occurs in natural barrier settings, providing a convenient means to experimentally manipulate the groundwater hydrology within the barrier. The overall aim of the BARDEX II was to collect a large-scale data set of energetic waves acting on a sandy beach/barrier system to improve our quantitative understanding and modeling capability of shallow water sediment transport processes in the inner surf, swash, and overwash zone. In this paper, we introduce BARDEX II and provide a detailed description of the experiment, including the experimental design, instrumentation, test program, and data set, as well as presenting some examples of the morphological and hydrodynamic data set. We also reflect objectively on the strengths and weaknesses of the data set. This paper serves as an introduction to a special issue of Coastal Engineering, solely devoted to the results of BARDEX II. (C) 2015 Elsevier B.V. All rights reserved.
