Tasks
  • Comprehensive Hydrodynamic Numerical Modeling of
    Tsunami Behavior from Generation to Inundation
  • Experimental Investigation into Nearshore Tsunami
    Evolution and Impact
  • Education, Outreach, and Training

3
Comprehensive Hydrodynamic Numerical Modeling of
Tsunami Behavior from Generation to Inundation
  • Hybrid Modeling for Multi-Scale Simulation
  • Integrate large-scale, mid-scale, and fine scale
    models
  • Coupled directly, such that the different models
    are running simultaneously and passing boundary
    data to each other
  • Generation/Propagation (N) LSW
  • Nearshore NLSW or Boussinesq
  • Fine scale, vertically varying coastal dynamics -
    RANS

4
Goals
5
  • Bous 2D RANS developed for wind wave simulation

6
  • Example Bous 2D RANS

7
  • Example Bous 2D RANS

8
Comprehensive Hydrodynamic Numerical Modeling of
Tsunami Behavior from Generation to Inundation
  • Numerical Wave Tank Model of the OSU Tsunami Basin

3D RANS
Bous
9
Comprehensive Hydrodynamic Numerical Modeling of
Tsunami Behavior from Generation to Inundation
  • Tsunami Open Source (TSUNAMOS)
  • All codes, individual and hybrid, will be freely
    available
  • Couplings well documented, other modelers can
    plug-in
  • Will adopt OpenSees-ish simulation builder
    framework

10
Experimental Investigation into Nearshore Tsunami
Evolution and Impact
  • 3D Nearshore Turbulent Effects
  • Breaking
  • Bottom friction

11
Experimental Investigation into Nearshore Tsunami
Evolution and Impact
  • Part 1 of Experimental Plan
  • Wavemaker-focused solitary wave breaking over
    flat bottom
  • Solitary wave breaking due to simple refraction
    focusing

12
Experimental Investigation into Nearshore Tsunami
Evolution and Impact
  • Part 2 of Experimental Plan
  • Use a complex bathymetry/topography
  • Will be decided upon after community input
  • Payload projects
  • Could involve reef/dune breaks, irregular
    coastline, harbor etc.

13
Experimental Investigation into Nearshore Tsunami
Evolution and Impact
  • Experimental Plan
  • Use simple waves, as well as real waves.
  • NWT to determine board motion

Time series from numerical model used to drive
wavemaker
14
Education, Outreach, and Training
  • Integrated outreach and education programs in
    Hawaii and Caribbean
  • Use of TSUNAMOS for tsunami coastal impact
    studies
  • 3 training workshops _at_ UPR
  • Operators of critical coastal infrastructure
  • train the trainers
  • Tsunami/coastal engineering seminar
