2Tasks
- Comprehensive Hydrodynamic Numerical Modeling of
Tsunami Behavior from Generation to Inundation - Experimental Investigation into Nearshore Tsunami
Evolution and Impact - Education, Outreach, and Training
3Comprehensive 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
4Goals

9Comprehensive 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
10Experimental Investigation into Nearshore Tsunami
Evolution and Impact
- 3D Nearshore Turbulent Effects
- Breaking
- Bottom friction
11Experimental 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
12Experimental 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.
13Experimental 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
14Education, 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
