Upgrading Oregon State's Multidirectional Wave Basin for Remote Tsunami Research

小乔治·E·布朗。地震工程模拟网络(NEES)计划是美国国家科学基金会重大研究设备计划资助的一个项目。这项合作协议根据NEES计划，在俄勒冈科瓦利斯的俄勒冈州立大学辛斯代尔波浪研究实验室(WRL)建立了一个NEES海啸/海浪盆地研究地点。该奖项是对提交给NSF 00-6计划征集项目“NEES：地震工程研究设备”的建议进行同行评审的结果。该奖项提供了以下设备：(1)长冲程、高速、定向、孤立波发生器，(2)速度传感器，(3)视频工作站，(4)数据库和文件服务器，(5)扩展现有的数据采集系统，以适应远程观测、远程操作、远程传输和远程存储，以及(6)具有远程观测和远程操作能力的设备，以便通过高性能的网络连接对设备上的实验进行观察和控制。为了适应新的波浪发生器和海啸试验，俄勒冈州立大学将把西铁现有的3-D波浪池设施扩大到26.5米x 48.8米x 2.0米深，并在波浪池上提供一台桥式起重机。该盆地将配备电阻波浪仪，以提供准确的局域波测量，并验证其他成像技术(视频、激光、雷达和声学)，以增加对波浪绕射和折射图案的空中覆盖。该设备将于2004年或更早投入使用，并将作为国家共享的NEES设备场地进行管理，具有远程观测和远程操作能力，以提供新的地震工程研究测试能力，用于测试和验证海啸-波浪/结构相互作用的高级分析和数值模型，用于到2014年的所有海洋、沿海和港口研究。共享使用准入和培训将通过NEES联盟进行协调。该NEES设备点将通过千兆以太网连接到位于西北计算科学与工程联盟(NACSE)的信息管理设施，与NEES协作室相连。向远程站点的数据传输将通过Internet2的S阿比林网络进行。将使用数码相机为当地和远程调查人员同时提供多个参照系和视野，以增强物理模型体验。此外，全动态摄像机、新的数据采集系统和全面的信息架构将使本地和远程用户能够在不同级别的分析中快速检查选定的数据通道。将建立一个海啸实验数据库，以便更广泛的地震工程研究团体可以研究海啸实验的结果，减少对实验的需求，并为验证数值模型提供数据。该大学将把这种海啸/波浪池设备整合到其研究计划、本科生和研究生教学以及K-12和社区推广中。该大学还将通过现场课程和讲习班以及网络材料为外部研究人员提供培训机会，以帮助其他机构的大学教员将海啸测试经验纳入本科生和研究生课程。

The George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) Program is a project funded under the NSF Major Research Equipment Program. This cooperative agreement, under the NEES Program, establishes a NEES tsunami/wave basin research site located at the O.H. Hinsdale Wave Research Laboratory (WRL) on the Oregon State University, Corvallis, Oregon, campus. This award is an outcome of the peer review of proposals submitted to program solicitation NSF 00-6, "NEES: Earthquake Engineering Research Equipment." The following equipment is provided under this award: (1) long-stroke, high velocity, directional, solitary wave generator, (2) velocity transducers, (3) video workstations, (4) database and file server, (5) expansion of the existing data acquisition system to accommodate teleobservation, teleoperation, teletransmission, and telestorage, and (6) equipment for teleobservation and teleoperation capabilities so that experiments on the equipment will be observable and controllable via high performance network connections. To accommodate the new wave generator and tsunami experimentation, Oregon State University will expand its existing 3-D wave basin facility at the WRL to 26.5m x 48.8m x 2.0m deep and provide a bridge crane over the wave basin. The basin will be equipped with electro-resistive wave gauges to provide accurate, local wave measurements and to validate other imaging techniques (video, laser, radar and acoustic) to increase aerial coverage of wave diffraction and refraction patterns. This equipment will be operational by 2004 or earlier and will be managed as a national shared-use NEES equipment site, with teleobservation and teleoperation capabilities, to provide new earthquake engineering research testing capabilities for test and validation of advanced analytical and numerical models of tsunami-wave/structure interactions for a full range of ocean, coastal, and harbor studies through 2014. Shared-use access and training will be coordinated through the NEES Consortium. This NEES equipment site will be connected to the NEES collaboratory via a Gigabit Ethernet link to the information management facilities located at the Northwest Alliance for Computational Science and Engineering (NACSE). The transmission of data to remote sites will take place via Internet2's Abilene Network. Digital cameras will be used to enhance the physical model experience by providing multiple, simultaneous frames of reference and fields of view for both local and remote investigators. In addition, full-motion cameras, a new data acquisition system, and a comprehensive Information Architecture will allow local and remote users to rapidly examine selected data channels at various levels of analysis. A Tsunami Experiment Databank will be established so the broader earthquake engineering research community can study the results of tsunami experiments, reducing the need for experimentation and providing data for validating numerical models. The University will integrate this tsunami/wave basin equipment into its research program, undergraduate and graduate instruction, and K-12 and community outreach. The University will also provide training opportunities for outside researchers through on-site courses and workshops, and web-based materials that will assist university faculty at other institutions to incorporate tsunami test experiences in undergraduate and graduate courses.
