This app calculates height of wave, distance and arrival time to the seashore.

INPUT
- Altitude of eyes.
- Max depth of ocean.
- Max depth of shelf sea.
- Width of shelf sea.
- Lap time until being able to see the wave foot, since being able to see the wave head.

OUTPUT
- Wave height on the ocean.
- Wave height entered into the sea shore.
- Distance to the seashore.
- Arraival time.

NOTE:
These results are guess level, these are different from the real.
The mirage on the horizon is not considered.
If an inlet, the wave becomes higher than this calculation result.
The arrival time becomes shorter than it, too.
