Abstract
The character of alluvial deposits reflects the morpho-dynamics of the associated river. The first order effects on morpho-dynamics are topographic gradient (including base level), and the upstream supply of sediment and water. The dominant role of water discharge on river channel dimensions is a major reason for the potential effect of climatic change on the extent and nature of fluvial deposits. Interpretation of the climatic signal that may be present in fluvial deposits requires understanding of the processes and time scales of river channel adjustment. For several decades fluvial geomorpologists have worked to understand these issues but mostly at small spatial scale and short time scales relative to the issue of Quaternary adjustments in large river systems. This paper will consider what might be the contribution of contemporary fluvial morpho-dynamics to an understanding Quaternary fluvial sedimentation in Canada?
