Abstract
This report provides an assessment of the potential impacts of the proposed Horns Rev 3 offshore wind farm development on hydrography, sediment spill, water quality, geomorphology and coastal morphology both offshore and along the nearest shore line of Denmark. In order to assess the potential impacts of the wind farm (including all associated infrastructure), the export cable corridor and the landfall site, relative to baseline (existing) conditions, a combination of detailed numerical modelling and expert assessment has been employed. These impacts have been assessed using the worst case characteristics of the proposed development as provided by the project and presented as the Technical Project Description (Energinet.dk, 2014). Considerations of the proposed impacts upon the wave, tidal current, sediment transport and water quality regimes have been made for the construction, operation and decommissioning phases of the development.
