• Ian Robertson
• Peter Yin
• Kuang-An Chang
• Guy Gelfenbaum
• Pat Lynett
• Elena Suleimani
• Julie Young
• Utku Kanoglu
• Shinji Sato

2
Bathymetry

• Remote control of experiments
• Absorption
• Horse hair side walls for fast wave damping

3
Usage of Basin

• Wave interaction with structures
• Permanent 1 on 20 beach as a basis for
  community?
• Ports and harbors models on top of slope?
• Granular flow, scaling issues for landslides

4
Usage of Basin

• Benchmark problems?
• Limitations for local effects modeling?
• Scaling effects?
• 3-D bathymetry
• Runups
• Challenges to 3-D motions

5
Usage of Basin

• Port is a big client
• Formation of an advisory panel?
• The first NEES Grant Challenge project is on
  ports. It focuses on the Port of Seattle
• Port of LA has Mofatt and Nichol conduct
  research. Would like to exchange knowledge and
  collaborate
• Create a generic port for the community?

6
Usage of Basin

• Scaling limitations forces us to focus on more
  local areas rather than large scale
  infrastructures
• A 1/15 or PI/45 slope will leave 30 ft of flat
  bottom for tsunami wave generation
• The beach at URI (20m X 3.6 m) cost 25K at
  approximately 40/sq.ft. for the TWB would be
  about 400K

7
Usage of Basin

• A flume and a 3-D basin side by side
• Dambreak physical simulation capability for the
  2-D flume

9
Collaboration

• New proposals
• Ports?
• Build much bigger breakwater?
• Scaling limitations
• Uplift of decks due to tsunami?
• West coast ports have strong anchoring for
  seismic design

10
Collaboration

• Important issue for Port design is the maximum
  current due to tsunami
• Huge ships 250,000 tons of debris flow
• Long channel 9-10 miles, 1000 ft wide, 53 ft
  deep) with high speed current
• What are the likely scenarios to design for?
• Hawaii small group project may collaborate with
  Georgia Tech GC project

11
Collaboration

• Payload projects

12
Instrumentation

• What are the needs?
• A variable depth sensor array
• Automated calibration
• Fiber Optic Backscatter Sensors
• Surface PIV
• More cameras
• Underwater PIV
