water depth
Subaqueous vertical measurement
Water depth is the vertical distance from the surface of a body of water to the bottom.
Charts show water depth for navigation; swimmers check water depth before diving.
The term appears in marine contexts, hydrology, and anywhere the measurement matters: The water depth here exceeds a hundred feet.
