Tidal Wave

The term tidal wave may refer to one of the following:

• A gigantic wave caused by the force of the moon and sun
• A tidal bore, which is a large movement of water formed by the funnelling of the incoming tide into a river or narrow bay
• A storm surge, or tidal surge, which can cause waves that breach flood defences
• A tsunami or harbor wave, although this usage is not favored by the scientific community due to tsunamis not being tidal.
• A Megatsunami, which is an informal term to describe a tsunami that has initial wave heights that are much larger than normal tsunamis.
