Resumen

This study was designed to evaluate the equilibrium beach concept for conditions of "rapidly" varying water level, experienced on the North American Great Lakes. It was determined that the mathematical expression h(x) = Ax2'3 is appropriate for describing sandy beach and nearshore profiles of the Great Lakes. In addition, a correlation was found between lake-level change and the shape factor A, that indicates a phase lag in beach and nearshore response to "rapidly" changing water level. Results from this study also raise some questions about the reliability of determining the shape factor A directly from sediment size. Reliability in the determination of A may be related to the stability shape of the profile relative to its equilibrium shape.
