Abstract
The relationship between waves and recession rate of cohesive bluff shorelines consisting of glacial till is explained in physical terms as a function of wave‐foreshore interaction. An equation is derived based on wave energy dissipation rate in the breaking zone and on wave shear stresses offshore of the breaking zone. Measured long‐term recession rates of bluffs along the North Shore of Lake Erie are compared to hindcast long‐term average wave power and related to the equations developed in this paper.Keywords
