A mobile-bed model study of Pointe Sapin Harbour, in the Gulf of St. Lawrence, resulted in construction of a detached breakwater and sand trap to prevent harbour entrance infilling. The sand trap is filling in at a faster rate than predicted from the model. This is partly due to incomplete modelling of the wave climate; partly to incorrect modelling of distribution of alongshore sand transport; and partly to a complex sand supply at the site. Nevertheless, the sand trap solution is performing well.
