This paper seeks to answer the question, How much of the internal tide propagating up Knight Inlet, British Columbia, is reflected by a right-angled bend? The internal tide in Knight Inlet is generated by the interaction of the barotropic tide with a shallow sill seaward of the bend. It then propagates in both directions as a traveling Kelvin wave. The up-inlet propagating wave then encounters the bend, where some of it may be reflected. The study is based upon 2 1/3 months of cyclesonde current matter data from four stations taken during the summers of 1981 and 1983. The vertical profiles of amplitude and phase of the M2 constituent of longitudinal velocity and density fluctuations are decomposed into a truncated series of normal modes for waves propagating both up-inlet and down-inlet. At the two stations up-inlet of the sill, acceptable fits can be obtained using only two up-inlet propagating waves, indicating that the data are compatible with the low reflection found by Webb an Pond (1986). At the two stations seaward of the sill, the up-inlet energy flux is of the same order of magnitude as the down-inlet flux, indicating a second source of internal tide seaward of those two stations. The results indicate that only 30--50% of the power removed from the barotropic tide is being fed into the internal tide in the summer.
