FUNWAVE workshop participantsThe University of Delaware, the Center for Applied Coastal Research (CANR), and the US Army Engineer Research and Development Center (ERDC) came together July 25 through 27, 2017 to host a FUNWAVE-TVD workshop.

The three-day workshop consisted of training sessions for new users of FUNWAVE, as well as presentations by practicing and experienced users. The workshop also provided an opportunity for researchers to share several new features to the FUNWAVE model including modeling of ship wave generation and its effects on the adjacent shorelines and meteotsunami simulation. Announcements were also made about the ongoing work with NHWAVE.

The IT Research Computing group supported this event by providing the 35 participants with HPC accounts on the Mills cluster. Because of this, users were able to use FUNWAVE on the Mills cluster in real-time during the workshop training sessions.

The presentations at this workshop covered a variety of topics including the modeling of nearshore surface waves and processes such as harbor resonance, nearshore wave transformation, refraction and diffraction with complex geometries, nearshore circulation, wave interaction with reefs and vegetation, and tsunami propagation and inundation from ocean basin-to nearshore scales.

PDF versions of the presentations are available here.

FUNWAVE is is a phase-resolving, time-stepping Boussinesq model for ocean surface waves at scales ranging from coastal wind waves to global tsunami propagation. This model was developed by Dr. Fengyan Shi’s and Dr. James Kirby’s research team at the University of Delaware in the 1990s.

FUNWAVE is an open-source code and has a large user community in the research field of coastal and ocean engineering. To facilitate large-scale computations on a High Performance Computing system, the code was re-developed recently using a more completed Boussinesq equations and the state-of-the-art TVD-type numerical solver, and parallelized using Message Passing Interface (MPI). The new version, called FUNWAVE-TVD, is in high demand among the coastal and ocean researchers seeking ‘phase resolving’ modeling of nearshore wave transformation, refraction and diffraction with complex geometries, nearshore circulation, wave interaction with coastal structures, and tsunami propagation and inundation.

FUNWAVE-TVD has been adopted by the U.S. Army Corps of Engineers Coastal Hydraulics Lab (USACE CHL) for use by its district offices in design and analysis work, and has been used extensively as the basis for tsunami hazard analysis in the National Tsunami Hazard Mitigation Program (NTHMP).

Dr. Shi and Dr. Kirby are being supported by USACE CHL to develop a multi-grid, two-layer Boussinesq model system for modeling ship-wakes their effects on coastal erosion.
