Description: Technical Note
PURPOSE: Wave diffraction is a fundamental wave transformation process that occurs at all coastal inlets. The purpose of this Coastal and Hydraulics Engineering Technical Note (CHETN) is to demonstrate the numerical modeling capability to represent wave diffraction and reflection available in the WABED (Wave-Action Balance Equation with Diffraction) model. The WABED model is available as a nearshore wave transformation model in the Coastal Inlets Research Program’s (CIRP’s) Coastal Modeling System (CMS). Performance of the model is examined in this CHETN with two physical model data sets. The first data set pertains to a detached semi-infinite breakwater in front of a natural inlet, and an inlet with dual jetties. The second data set pertains to an inlet protected either by reflecting or absorbing jetties. Wave diffraction, wave reflection, and consequences of these processes on numerically simulated currents are examined with the two-dimensional (2-D) circulation model M2D. Future technical notes in this series will describe the interface and report additional validation and enhancements of WABED.
