Title from cover. Includes bibliographical references. "Current velocities in a river, lake or other body of water are measured by placing the current meter into the flow and recording the rate of rotation of the rotor. The relationship between the linear current velocity and the revolution of the meter rotor is normally determined by calibrating the meter in a towing tank. Current meters are calibrated by towing them at different velocities over their working range"--Introduction, page 1. Water currents gccst Measurement DeZeeuw, C., author. Canada. Environment Canada.
