Recent erosion of the shoreline near Fort Anne National Historic Park has removed a protective band of saltmarsh that existed for decades, and exposed the foundations of fortress embankments to the action of wind-generated waves at times of high water. Examination of aerial photographs suggests that the marsh was intact during the 1940's and 1950's, but began to disappear during the l960's and 1970's.

It is concluded that factors affecting erosion on the shore are primarily local, and that construction of a comprehensive hydrodynamic model is probably not necessary in order to make sound choices regarding the design of protective works effective in the long term. It is recommended that a further local study of shear stress over the near foreshore be carried out to provide a basis for design of 1ong-term protection, and that short-term protection against wave action be provided immediately.
