Alderney Race hydrodynamics: measurements and modelling

Duration: 36 months (2016 - 2019)


Improving energy production estimation is a key aspect of research in the field of offshore renewable energy. The typical error in tidal current prediction at tidal energy sites is about 10%, which results in a 30% error for the tidal power estimation. To reduce these errors, wave-current interactions need to be correctly taken into account in hydrodynamic numerical models.


To determine the yield of different turbines at a tidal farm in the Alderney Race, taking into account local hydrodynamics and sea states.

Scientific and technical contents

  • In-situ and high-frequency radar observations to obtain a better understanding of wave-current interaction processes, and thus fine-tune the configuration of numerical models
  • Construction of a numerical platform for the prediction of hydrodynamics in the Alderney Race
