Upgrading Oregon State's Multidirectional Wave Basin for Remote Tsunami Research S.C. Yim, C.M. Pancake, and C.K. Sollitt Project Overview Goals: Develop 3-D directional wave basin facility for tsunami/coastal community to enhance research and enable remote experimentation Basin Extension: Before Length: 87 ft; Width: 60 ft; Depth: 5 ft After Length: 160 ft; Width: 87 ft; Depth: 7 ft Wave Generator: Before Stroke : 3 ft; Velocity: 1.6 ft/s; Wave Height: 0.7 ft After Stroke : 6 ft; Velocity: 6.1 ft/s; Wave Height: 2.6 ft Host open codes and discussion forum on analytical and numerical models Host database of existing tsunami experiments Provide forum for calibration of numerical codes with experimental results

Status and Schedule of Tsunami Basin Project Wave basin and building extension (4/2/ /11/2002), performance site survey, contracted architect, completed schematic design, design specification development in progress Tsunami Wave generator acquisition (5/14/2001-2/19/2003), selected vendor (MTS), obtained State approval, awaiting NSF subaward approval Data acquisition system (8/1/2001-9/30/2004), on schedule Data management system (4/2/2001-9/30/2004), installed database server and initial middleware, developing tool-kit support middleware Remote access software design (6/18/2001-9/30/2004), on schedule High-performance network connection (4/2/2001-9/30/2004), extended Gigabit Ethernet to and install high-speed switch at Wave Research Lab, identified initial on-campus collaborators for testing Configuration testing (5/26/2003-9/24/2004), on schedule NEES Collaboratory operation (10/1/2001-9/30/2004), initiated interaction with NEES Consortium Developer

Most Critical Information/Answers for SI and CD Oregon State’s Tsunami Wave Basin has strong support from Tsunami/ Coastal research community In addition to the 3-D Tsunami Basin, Oregon State Wave Research Lab’s 345 ft x 15 ft x 12 ft, 2-D Long Channel is also vital to Tsunami research and should be included as part of NEES Equipment per Tsunami Basin/Research Community Workshop (April 2001) discussion Usability Engineering will enhance telepresence to make it possible for researchers to remotely communicate experiment controls, enhance human observation, share experiences, and re-use experiments. Experiment replay will allow marking of interesting events, zooming forward in fast/slow-motion, and downloading of sequences of data. Usability Engineering will be achieve through working with key users to identify needs and preferences.

Most Critical Questions for SI and CD Metadata: What is not automatically generated during experiments, must be defined by the PI. ES/SI/CD community must set standards. Who and what? Data Formats: Standards must be set for raw data, first-order filtered data, and published data. Decisions will need to be made regarding low-resolution and high-resolution data. Who and what? Required Hardware and Software: What are they and who would provide the purchasing, development, installation and maintenance costs? Composition of Consortium: What would the composition of the Consortium be by 1 OCT 2004? How would CD ensure equitable representation? Maintenance and Operation Funding: How would the Consortium decide on yearly funding at each equipment site? A minimum level to maintain physical equipment and network and technical support is needed at each site to ensure equipment are always in operational condition over the period? Experiment Fee Schedule: What are the means of determining fee structure for equipment users? Would the fees be different for NSF and other government agencies vs. academic and commercial users?
