dc.description.abstractMorphological changes along several channels have raised concerns in the Province of Manitoba. This thesis presents a comprehensive study of fluvial morphological processes in open channels. Due to the recent concerns in the Province of Manitoba, the study mainly focused on the Red River in the city of Winnipeg, and two diversion channels in northern Manitoba. Morphodynamic conditions of these channels have become more complicated due to the cohesive nature of the channels bed and bank material and significant effects of subaerial processes. Several field measurement techniques, experimental setups, and numerical models were used to gain a better understanding of these complicated processes within the study reaches. Field measurements include soil sampling, water sampling, hydrometric surveys using an ADCP; the experimental setup includes several standard soil properties tests as well as an erosion measurement test; numerical modelling includes hydrodynamic and thermal modelling to quantify applied shear stress and seasonal freeze-thaw processes. Moreover, the effect of deposition processes on the final geomorphology of the study areas is discussed.en_US
