"""
Plot results at gauges to compare with Figure 5 of Matsuyama et al. (2007).
Blue curves are the GeoClaw results.

Wavetank data for some of the gauges is available in the file
data_wavegauge.csv (kindly provided by Prof. Matsuyama).
At these gauges the observations are also plotted as red curves.
