The Midway Forecast Model Grids provides bathymetric data strictly for tsunami inundation
modeling with the Method of Splitting Tsunami (MOST) model. MOST is a suite of numerical
simulation codes capable of simulating three processes of tsunami evolution: generation,
transoceanic propagation, and inundation of dry land. Tsunami waves are computationally
propagated across a set of three nested grids (A, B, and C), each of which is successively
finer in resolution, moving from offshore to onshore. Nearshore details are resolved
to the point that model output can be directly compared with tide gauge observations
and can provide estimates of wave arrival time, wave amplitude and simulation of wave
inundation onto dry land. A Grid Resolution: 60 arc-sec. B Grid Resolution: 6 arc-sec.
C Grid Resolution: 2 arc-sec. |
