Long-Term Coastal Inlet Channel Area Stability

Abstract

The equilibrium-area concept for tidal inlets has been a useful approach to understand the adjustment of an entrance channel's minimum cross-sectional area to the basic hydraulic and sedimentation characteristics of the inlet and bay it serves. This paper examines the concept in terms of inlets that apparently are not in equilibrium, maintaining a smaller area than the equilibrium area that is indicated by the Escoffier diagram. Is the Escoffier approach too simplified or is the response sometimes a very long-term process? Other methods and concepts imply equilibrium area values smaller than predicted by the Escoffier approach.
