MRI: Acquisition of a Directional Random Wave Generator for the Coastal Engineering Laboratory Wave Basin

摘要德克萨斯农工大学工程学院和土木工程系致力于将海岸工程作为其研究的重点领域之一。学院于2002年9月完成了一个新的海岸工程实验室，该实验室包含一个22.8米、36.6米、1.5米深的波浪盆地，使其成为美国学术机构中最大的波浪盆地。该盆地将用于研究三个领域：近岸海岸过程、波构相互作用和海岸环境动力学。在三维盆地中，将设计、建造和安装一个分段的、多向的随机造波器，以产生水深达1.2 m的短周期和长周期波。造波器的行程约为一米，足以产生短波和长波。此外，该设备将能够产生孤子、定向波、聚焦波和散焦波。将通过远程观测能力鼓励远程用户的参与。该设备将用于研究具有国家和民族意义的研究问题，以及解决实际问题的应用研究。研究将包括风暴潮和海浪对人类安全和基础设施的影响，通过研究波浪结构相互作用、波浪流体动力学（如洪水和淹没）、侵蚀和沉积物运输、冲刷和泥石流等领域。它还将用于研究沿海地区波浪和洋流对形态演化的影响。实验室运行和维护的主要支持来源将来自国家倡议、国家研究资助和行业测试。研究生和本科生将使用这些设备。来自地理、海洋学和工程学的小组将使用这些设备将研究与教学结合起来。每组用户都将接受与其设备预期用途相称的培训。一些用户将仅仅是正在进行的实验的观察者，而其他用户，主要是硕士和博士研究生，将实际进行实验。非居民研究人员的培训将通过实验室的实践培训和基于网络的指导，在个案的基础上提供给特定用户。基于网络的教学将使用实验室的远程观测能力。对于许多人来说，实验室和三维设备将作为一个学习机会，以更好地了解波浪和洋流动力学以及造成飓风和沿海风暴广泛破坏的过程。我们的教育使命将包括通过现有的校园项目整合k -12和本科研究的研究和教育，以确保为代表性不足的群体提供设备。

AbstractThe College of Engineering and Department of Civil Engineering at Texas A&M University is committedto Coastal Engineering as one of the research growth areas. The College completed a new Coastal Engineering Laboratory inSeptember 2002 that contains a 22.8m by 36.6m by 1.5m deep wave basin, making it the largest wavebasin at a US academic institution. This basin will be used for studying three areas: nearshore coastalprocesses, wave-structure interaction and coastal environmental dynamics.In the three-dimensional basin, a segmented, multidirectional random wavemaker will be designed,constructed, and installed to generate short and long period waves in a water depth up to 1.2 m. Thewavemaker will have a stroke of approximately one meter, which is adequate to generate both short andlong waves. Additionally, the equipment will be capable of creating solitons, directional waves andfocusing and defocusing waves. Participation of remote users will be encouraged through teleobservationcapabilities. The equipment will be used to study research issues of state and nationalsignificance as well as applied research addressing practical problems. Studies will include the effects ofstorm surges and ocean waves on human safety and infrastructure by studying areas of wave-structureinteraction, wave hydrodynamics such as flooding and inundation, erosion and transport of sediments,scour, and debris flow. It will also be used to study the influence of waves and currents in the coastalzone on morphological evolution. Major sources of support for the operation and maintenance of the laboratory will be fromState initiatives, national research grants and industry testing.Students at the graduate and undergraduate level will use the equipment. Groups from geography,oceanography and engineering will be using the equipment to integrate research with teaching. Eachgroup of users will be given training commensurate with their intended use of the equipment. Some userswill be merely observers of ongoing experiments and others, primarily of graduate MS and Ph.D.students, will actually be conducting experiments. Training for non-resident researchers will be providedto the specific users on a case-by-case basis through hands on training in the laboratory and via-webbased instruction. The web-based instruction will use teleobservation capabilities in the laboratory. Formany, the Laboratory and the three-dimensional equipment will serve as a learning opportunity to betterunderstand wave and current dynamics and the processes causing the extensive damages of hurricanesand coastal storms. Our educational mission will include the integration of research and education fromK-12 and undergraduate research through existing campus programs that will ensure the availability ofthe equipment to underrepresented groups.
