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.

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研究增长领域之一。 学院于2002年9月完成了一个新的海岸工程实验室，其中包括一个22.8米乘36.6米乘1.5米深的波浪池，使其成为美国学术机构中最大的波浪池。该盆地将用于研究近岸海岸过程、波浪与结构相互作用和海岸环境动力学三个领域。在三维盆地中，将设计、建造和安装分段的、多方向的随机造波机，以在水深达1.2 m的水域中产生短周期和长周期波浪。造波机的冲程约为一米，足以产生短波和长波。此外，该设备将能够产生孤子，定向波和聚焦和散焦波。将通过远程观测能力鼓励远程用户参与。这些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，方法是研究波浪-结构相互作用、洪水和淹没等波浪流体动力学、沉积物的侵蚀和运输、冲刷和泥石流等领域。它还将用于研究海岸带波浪和海流对地貌演变的影响。实验室的运行和维护主要来自国家倡议、国家研究赠款和工业测试，研究生和本科生将使用这些设备。来自地理学、海洋学和工程学的团体将使用这些设备将研究与教学结合起来。每组用户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，而其他人，主要是研究生和博士生，将实际进行实验。非常驻研究人员的培训将通过实验室实践培训和网络教学，根据具体情况向特定用户提供。基于网络的教学将使用实验室的远程观测能力。对许多人来说，该实验室和三维设备将是一个学习机会，可以更好地了解波浪和海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从K-12和本科研究通过现有的校园计划，将确保设备的可用性，以代表性不足的群体的研究和教育的整合。
