Tidal prism refers to the volume of water that is exchanged between a tidal body of water, such as an estuary or a coastal bay, and the open sea during a tidal cycle. It is the difference in water volume between high tide and low tide in a specific location. Tidal prism can be calculated by measuring the area of the water body and the change in water level (i.e., the tidal range) during the tidal cycle.
