Location: Hauula—Punaluu region, Hawaii 
Period of Coverage: N/A 
Contents: This publication addresses a two-dimensional, time-dependent numer- 
ical model which was developed to calculate the land inundation of a tsunami. 
The model solves long wave equations that include bottom friction terms. A 
coordinate transformation was used to allow the model to employ a smoothly 
varying grid that allows cells to be small in the inundation region and large 
in the ocean. This model was applied to a region of Hawaii and produced 
10 figures showing the contours of 50- and 100-year tsunami inundations. 
These figures can be overlaid on maps referenced in the report to delineate 
detail extents of flood inundation.
