Abstract
Shoreline erosion resulting from wind-generated waves has been noted
as a problem on coastlines and inland water bodies the world over.
In order to determine if computer simulation techniques are of any use
in estimating erosion rates along the shoreline of existing and future
reservoirs on the Canadian Prairies, hindcasted waves were tracked to
the breaker line on Lake Diefenbaker, Saskatchewan.
This thesis presents a method of using predicted wave power values to
estimate potential rates of erosion. The study found that enough
wave energy is generated on the reservoir to remove all eroded
material from the shoreline, regardless of its source of origin. The
predicted rates of erosion were comparable to those observed. The
study also found that varying water levels are of little help in
retarding the process of erosion on Lake Diefenbaker, because of the
cohesive nature of the shoreline sediments.
