Science / Tides and Currents / Shallow Water Wave: A wave is classified as a shallow water wave whenever the ratio of the depth (the vertical distance of the still water level from the bottom) to the wave length (the horizontal distance between crests) is less than 0.04. Such waves propagate according to the formula: C = %gd where C is the wave speed, g the acceleration of gravity, and d the depth. Tidal waves are shallow water waves.
