For tidal stream devices, kinetic energy in the water column is proportional to the cube of the water velocity.  In order to optimise device performance, correct location is therefore essential.
Coastal Science can predict the temporal and spatial variations in tidal velocity field in and around the proposed location, and then measure them efficiently, as follows:

High resolution hydrodynamic modelling, at 50m resolution or better, will provide a detailed synopsis of flow variability in the area of  interest.   Timeseries of velocities at specific locations are also output for analysis.   Modelling represents a very cost-effective and rapid means of characterising the site and targeting marine surveys.

Oceanographic and geophysical surveys will almost certainly be required before device deployment.  From the modelling exercise the potential locations for current meter deployment are well defined.  The fieldwork can therefore be fully targeted, saving time and money.  Coastal Science undertakes Specification, Management and on-site Representation for coastal surveys.

 

Coastal Science is presently developing a range of high resolution hydrodynamic models which target sites under consideration for tidal stream generation.  Output from these models, and associated analysis, is being made commercially available on a non-exclusive basis at very low cost, with the option to further develop and configure the models to your requirements on an exclusive basis if desired.  Please get in touch for more information.

 

Coastal Science has a strong track record of undertaking Hydrodynamic and Water Quality Characterisation and Impact Assessment studies for a wide range of marine development scenarios, from the Severn Barrage Options to Marina Developments in the Persian Gulf.

Detailed and accurate 2D or 3D modelling will provide a robust description of the Hydrodynamic and Water Quality environment before and after scheme development.  Output from the modelling studies will then be used for design optimisation, or fed in to the wider EIA process

Oceanographic and geophysical surveys will often be required in order to underpin the desk-based studies.  Coastal Science undertakes Specification, Management and on-site Representation for Hydrographic and Geophysical coastal surveys.

Coastal Science has thirteen years experience of predicting, assessing and optimising the near- and far-field dispersion of marine discharges, from small Waste Water Treatment Works effluent flows of just a few litres/second, to Large Combustion Plant cooling water discharges of many tens of cubic metres per second.

Near field characterisation of the effluent plume is generally undertaken with the industry standard CORMIX. Output is then considered in the light of experience and available data before recommendations for outfall design optimisations are made. For far-field impact assessment, Coastal Science routinely applies Delft3D and Mike hydrodynamic and water quality models.

Oceanographic surveys - current metering, dye tracing, etcetera- will be required in order to improve site knowledge and for model calibration purposes. Coastal Science undertakes Specification, Management and on-site Representation for coastal surveys.
