Portland, Maine Tsunami Forecast Grids for MOST Model
The Portland, Maine 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: 12 arc-sec in x direction. 9 arc-sec in y direction. C Grid Resolution:
4/3 arc-sec in x direction. 1 arc-sec in y direction.
