Abstract

The increased rate in sea level rise and other predicted effects of climate change associated with global warming, will inevitably lead to geomorphic changes on the Roberts Bank tidal flats on the Fraser River delta of southwest British Columbia. A dyked landward edge limits the amount of accommodation space available for the tidal flats and marsh to adjust to higher sea levels. This lack of space combined with the training of the Fraser River, which has contributed to a shortage of sediment supply, will affect the morphologic changes of the ecologically important tidal flat. Current biosedimentological zonation maps and cross-shore profile data are used to identify and understand potential morphologic changes. Copyright ASCE 2006.
