| Title | TSUNAMOS: A Validated, Multi-Scale Tsunami Model for Hybrid Numerical-Experimental S imulation (Phase II) | |||||
| 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. Phase II will begin in July 2008 utilizing a 1:15 to 1:30 beach constructed in the Tsunami Wave Basin. The roughness type will include both fixed and movable sand and gravel, stripes and wires (simulating bushes and trees), and small blocks (simulating small structures in the path of tsunami inundation). 2HD runup time series will be digitized from overhead cameras, and the inundation limit will be manually traced after each experimental trial. These experimental settings will simulate situations closer to what tsunamis encounter on natural beaches. With this data, accurate bottom dissipation models will be developed for transient tsunami flow, improving significantly upon the traditional approach. NSF award abstract | |||||
