| SGER NEESR Payload Project to NEESR SG Award CMS-0530759: Leveraging Tsunami Researc
h - Wave Loading on Residential Structures with Earthquake and Hurricane Applications
|
| What
| The objective of this payload proposal is to install typical residential structural
models on the other side of the wave basin during testing in order to investigate impact d
ue to wave loading and run-up, and wind/pressure driven surge. Two single family dwelling
models typical of coastal construction in the U.S. will be installed on a flat surface ab
ove the waterline representing coastal property. Areas impacted by the results include: (1
) information on fluid impact loads as a function of different wave heights and ground slo
pes on residential structures, (2) an understanding of the load transfer mechanism and up
lift forces on residential structures during wave and surge loading, (3) the relationship
of scale model pressure to full-scale prototype damage, and (4) information for designers,
innovators, and public policy and decision-maker.

| Development of Performance-Based Tsunami Engineering, PBTE
|
| What
| The proposed research will develop the methodology and validated simulation tools fo
r implementation of site specific Performance Based Tsunami Engineering (PBTE) for use in
the analysis, evaluation, design and retrofit of coastal structures and facilities, and co
de-compatible provisions for tsunami resistant structural design. Coastal inundation model
ing will be developed to redraft the inundation mapping for the Hawaiian Islands. The anal
ytical simulation tools will be validated through extensive experimentation at the Tsunami
Research facility at OSU. The Tsunami Wave Basin will be used to develop and validate co
astal inundation codes including the influence of coastal plan and bathymetric variations,
and 3-D RANS (Reynolds-Averaged Navier Stokes) simulations of fluid-structure interaction
. The Longitudinal Wave Basin will be used to validate the scour modeling and to study the
effect of floating debris on structural elements.

|
| What
| The proposed research program aims at achieving the following scientific objectives: 1. to understand the mechanism of landslide generated tsunamis and the associated runup and rundown, 2. to understand the dynamic interactions among tsunamis, rigid and flexible structures, and moving objects, 3. to improve the modeling capability of complex runup flows within the context of their interactions with flexible and moving objects, and 4. to develop benchmark problems with high quality experimental data for validating numerical simulation models.

| Title
| TSUNAMOS: A Validated, Multi-Scale Tsunami Model for Hybrid Numerical-Experimental Simulation
|
| What
| The objectives of the proposed research program are to 1) improve understanding of nearshore, three-dimensional tsunami evolution through an extensive set of physical experiments using NEES facilities; 2) create an extensible framework to provide a systematic structure for validating computational models with experimental and field data; 3) refine modeling capabilities and couple the various components together to create a multi-scale simulation tool; and 4) develop a sustainable education and outreach program that educates the general public about tsunamis and appropriate responses to them. Nearshore evolution of tsunami waves, such as 3D breaking through focusing and bathymetry, and overland flow across irregular and rough topographies, will be investigated. Concurrent to the experimental effort, a comprehensive tsunami simulator, TSUNAMOS (Tsunami Open Source Community Model), will be developed.
Phase I took place in the spring of 2007. The purpose of this set of
experiments was to obtain a detailed and dense set of free surface and
velocity measurements for 3D tsunami (long wave) breaking. Breaking will be
induced through wave focusing. There was no bathymetry in the Tsunami Wave
Basin during this phase; it was a flat bottom.

| Title
| NEESR-SG: Physical modeling of 3D Tsunami Evolution Using a Landslide Tsunami Generator
|
| What
| The ultimate long-term goal is to develop a fundamental understanding of the mechanism of tsunamigenic landslides and subsequent tsunami generation, propagation, and run-up. This would allow for improved assessment and possible mitigation of the landslide and tsunami hazard. The goal of the proposed research is to compensate for lack of real world landslide and tsunami data, by the physical modeling of 3-dimensional tsunami evolution using a novel landslide tsunami generator, which will complement the existing NEES tsunami facility at OSU.. The design parameters for the proposed landslide tsunami generator will be determined using governing model similitude and dimensional analysis of the landslide and tsunami characteristics. The size of the NEES tsunami wave basin will provide the unique opportunity to study scale effects of tsunami generation and propagation based on a non-dimensional scale series.

| Pilot Study in support of NEESR-SG: Development of Performance-Based Tsunami
Engineering, PBTE
|
| What
| This pilot study investigated harmonic wave runup on a beach with varying slopes. The wave breaking, bed scour, and sediment transport were also studied. Harmonic waves with a wide range of height and period were generated. The wave height, velocity, and sediment concentration at differential locations near the breaking and runup region were recorded and analyzed for comparison with model results.
