WABED Model in the SMS: Part 2. Graphical Interface

Abstract : This Coastal and Hydraulics Engineering Technical Note (CHETN) describes the graphical interface for the Wave-Action Balance Equation Diffraction (WABED) model that has been added to the U.S. Army Corps of Engineers (USACE) Surface-water Modeling System (SMS). WABED is intended for applications in calculating wave transformation at coastal inlets and is part of the Coastal Modeling System (CMS) developed under the Coastal Inlets Research Program (CIRP) for simulating combined waves, currents, sediment transport, and morphology change. This CHETN describes the graphical interface of WABED available in SMS Version 9.2, which is similar to that of the half-plane STWAVE Version 3.0 (Smith et al. 2001). The SMS (Zundel 2006) is a graphically interactive computer program designed to facilitate the preparation and application of USACE numerical models. This package currently supports several circulation, wave, and sediment transport models and has recently been modified to generate input files for and visualize computed results of WABED. Various features, tools, and analysis capabilities outlined in this document are designed to enhance the ability of engineers to efficiently utilize WABED in the CMS. The model and its interface are expected to evolve with additional applications, and the current interface will continue to undergo revision. The theoretical background and user's manual for WABED are given by Lin et al. (2006) [see ADA452387, Wave-action balance diffraction model tests of wave diffraction and reflection at inlets, ERDC/CHL CHETN-III-73] and Demirbilek et al. (In preparation. WABED: A nearshore spectral wave processes model for coastal inlets and navigation projects).
