This thesis examines the barotropic M2 tidal circulation and associated oceanographic
properties in the Kyuquot Sound. The main contribution of this thesis is
the development of a simple analytical model based on results from a Finite-Volume
Coastal Ocean Model (FVCOM), describing a two-channel system. The simple analytical
model allows us to estimate the energy dissipation rate in Crowther Channel
and recognizes that friction is responsible for phase difference (between currents and
elevation) variations as we move along the channel. This is done without running complex
numerical models or collecting extensive observation data. We found a difference
in velocity phases between a dominant channel (Kyuquot Channel) and a secondary
channel (Crowther Channel) in Kyuquot Sound. The velocity phase response in the
secondary channel is out of phase with the dominant channel, and varies when we
move along the channel, while the elevation phases are consistent between the two
channels. This result has a potentially significant impact on future biological and
navigation decisions. Our research is also focused on getting a general understanding
of the circulation in Kyuquot Sound, and offers an energy budget comparison between
the analytical and numerical model results. These results allow the contrast between
the simple analytical and the numerical model to be clarified, as the advantages and
limitations of both are discussed in detail. / Graduate / 0415 / 0759 / 0547 / diwan@uvic.ca
