Abstract


The paper summarizes the analysis of the coastal processes which have been responsible for the evolution of the Toronto Islands sand spit feature. Both natural and artificial influences have created a situation of a rapidly evolving landform. The purpose of the study was to evaluate the feasibility of rebuilding a school near the shoreline of this rapidly evolving feature. Several different techniques were employed to evaluate the changes including: shoreline recession rate estimates, lake bed surface change comparisons, sediment budget calculations and alongshore and cross-shore sediment transport calculations. These techniques were combined to develop a descriptive model of the changes in order to forecast future changes to the landform over the next 100 years.
