Abstract

Seven harmonic constituents (M2, S2, N2, K1, O1, M4 and MS4) of the tidal transports and streams through each of 22 sections across the St. Lawrence river and estuary are calculated from water level data and the principle of continuity. Excellent agreement is obtained with values of the same harmonic constituents deduced from direct current measurements in four of the cross-sections. It is suggested that the average tidal streams through the sections are more accurately determined from the tide gauge data and the principle of continuity than could be accomplished by direct curren t measurement.
