"""Validation of the AnuGA implementation of the shallow water wave equation.

This script sets up Okushiri Island benchmark as published at the

THE THIRD INTERNATIONAL WORKSHOP ON LONG-WAVE RUNUP MODELS
June 17-18 2004
Wrigley Marine Science Center
Catalina Island, California
http://www.cee.cornell.edu/longwave/


The validation data was downloaded and made available in this directory
for convenience but the original data is available at
http://www.cee.cornell.edu/longwave/index.cfm?page=benchmark&problem=2
where a detailed description of the problem is also available.


Run create_okushiri.py to process the boundary condition and build a the
mesh before running this script.
