    The magnitude shown in these videos and images tells you the speed of the water, but with no indication of the direction. In shallow areas this information can be useful in understanding the amount of sediment mixing caused by tides and the amount of shear stress (side ways rubbing) that these areas might experience. Shallow areas that have a high current magnitude are likely to be different habitats.
