6. Confrontation vs Mitigation EMBS – Edinburgh, 25 th August 2010 Potential negative impacts Species displacement Environmental conditions Colision risks Noise

7. Confrontation vs Mitigation EMBS – Edinburgh, 25 th August 2010 How good is the energy resource? How the energy is dissipated? Long term and far-field effects Scale up to arrays

9. Monitoring techniques EMBS – Edinburgh, 25 th August 2010 a) Satellite observations Optical wavelengths: suspended sediment concentrations Dopplerised SAR imagery: currents b) High Frequency (HF) Radar: surface currents and wave spectra Remote sensing a) ROV (Remote Observation Vehicles) b) Gliders ROVs and Floats

11. SUNTANS model EMBS – Edinburgh, 25 th August 2010 u, v, w are Cartesian components of velocity u is the vector form of velocity q the non-hydrostatic component of pressure η is the free surface elevation f and b are the Coriolis terms υ H and υ V are the horizontal and vertical turbulent eddy viscosities ∇ H the horizontal gradient operator: SUNTANS is a numerical model designed for the simulation of complex, non-hydrostatic coastal, river and estuarine flows with high resolution on unstructured grids using parallel computers.
