1. Erosion as a result of running water or wave action: The various fluviraptions in coastal areas are obviously caused by the actions of waves; especially, as a result of storms or tsunamis.
2. Washing away or the washing off of loose material; such as, earth, sand, etc. as a result of flowing water: Large waves, or a series of waves, caused by an earthquake that moved large quantities of water in the ocean, created all kinds of fluviraptions when they hit land.
