520	3 |a"Using dimensional analysis and basic wave theory, the wave conditions in a towing tank during current meter calibrations were examined. It has been shown that the existence of deep water waves and shallow water waves depends on the towing speed Froude number ��. Deep water waves exist when �� < 0.6 and shallow water waves exist when �� > 0.6. It was further shown, that when the towing speed approaches the velocity of a shallow water wave, current meters measure a velocity less than the towing speed, with the maximum deficit occurring when �� = 1. This phenomenon is known as the Epper effect. In the NWRI towing tank, the Epper effect occurs when the towing speed is 5.2 m/s"--Abstract, page iii.
