IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

ABSTRACT
A high-fidelity simulation-based approach has been developed to enable site-specific optimization of tidal, current and
wave energy conversion systems. The computational code is based on the Saint Anthony Falls Laboratory Virtual
StreamLab (VSL3D), which is able to carry out high-fidelity simulations of turbulent flow and sediment transport in
riverine and coastal environments taking into account the arbitrary geometrical complexity characterizing natural
waterways. The computational framework can be used either in device-resolving mode, to resolve all geometrical details
of a device, or with devices parameterized using actuator-based approaches. Locally refined grids are employed to
dramatically increase the resolution of the simulation and enable efficient simulations of multi-device arrays.
Device/sediment interactions are simulated using the coupled hydro-morphodynamic module of VSL3D. Device-wave
interactions are taken into account via a level-set fluid-structure-interaction (FSI) approach that enables the simulation of
arbitrarily complex floating structures under the action of complex waves. Site-specific wave fields can also be
incorporated in the code by coupling a far-field wave model with the near-field FSI model. The predictive capabilities of
the resulting computational framework were demonstrated by presenting simulation results for various cases for which
laboratory experiments have also been carried out. The utility of the simulation-based approach for guiding the optimal
development of turbine arrays in real-life waterways was also discussed.
