Question

is there a way to calculate what the wave tides would be like if there were two moons revolving around the earth?

Answer 1

I don't know if we can calculate the tide that results from one moon. I think there are just tables.

Answer 2

To calculate what wave tides would be like near shore, you would need to have detailed information about the geography of the shorelines. While one can calculate that the moon (and sun) raise tides of about 1 meter in the open ocean, it is the local geography that determines the timing of the tide, as well as the height of the tide. The same argument would apply to two moons.

You may be interested in reading some of this book though "What if the Earth Had two Moons" by Neil F Comins http://www.amazon.co.uk/What-Earth-Had-Moons-Thought-Provoking/dp/0312598920/ref=sr_1_1?ie=UTF8&qid=1310711376&sr=8-1(im sure you can find it in a library somewhere). The title says it all really.
