This work unit develops, validates, and implements advanced numerical wave modeling technologies which provide the USACE reliable and accurate wave estimates, and evaluates wave processes affecting navigation projects, coastal inlets and channels, ports and harbors and coastal beaches. It conducts basic research on coupling these wave models with flow and sediment transport models to calculate waves and currents for design and operation of channels, jetties, portsharbors, and coastal morphology change. This work unit develops capabilities for meteorological and oceanographic data analyses that are necessary for short- and long-term simulations of coastal inlet hydrodynamics and navigation processes, and implements these technologies in the form of web-based tools, WaveNet and TideNet. It continually upgrades the Coastal Modeling System s CMS wave model CMS-Wave, a phase-averaged spectral wave model, and BOUSS-2D, a Boussinesq-type nonlinear wave model. These models are required for calculation of waves over shallow reefs and porous structures with variable roughness, infra-gravity waves, runupovertopping, and wave asymmetry. Functional performance of USACE navigation projects can be evaluated with these models when coupled to flow and sediment transport models. Using laboratory and field measurements, the work unit verifies and validates the upgraded models for release to users. The work unit is developing WaveNet and TideNet, two web-based tools to access, visualize, and process wind, wave, and tide data for USACE project applications and RD needs.
