Including Nearshore Processes in Phase-Averaged Hydrodynamics Models

Abstract

The large spatial and time scales of the numerical modeling projects of the U.S. Army Corps of Engineers (USACE) requires the use of computationally efficient phase-averaged hydrodynamic models derived by averaging the equations of motion over a representative short wave period. Guidance in modeling nearshore regions with phase-averaged hydrodynamic models is provided herein. Physical processes unique to the surf zone are described along with methods of incorporating these effects to improve hydrodynamic predictions. Comparisons to detailed measurements from a laboratory basin experiment are used to demonstrate the significance of including processes unique to nearshore regions. To provide guidance that is applicable to varied phase-averaged models, details of the implementation are not provided herein, and the focus is on conceptual models
