True, as a wave enters shallower water, more of it is exposed - but they don't get higher. Shallow water also causes them to break as their natural height can no longer be supported.

What's why five foot waves on Lake Erie are much worse than Lake Michigan. On Erie, the wavelengths are only 25-30 feet and a five footer is breaking across most of western basin. On Lake MI, it's just a swell with a 75-100 foot wavelength.

Tsunamis have bigger waves that storms, because they more efficiently apply energy (direct kinetic energy from fault action on bottom) than wind (indirect application of wind energy).

Nuclear physicist, out.
That, is what I was trying to say.
