“…The possible impacts that proposed tidal developments could have on marine habitats are commonly discussed [16,61,6], as was recently well summarised by Gallego et al [62]. This work represents an early attempt at demonstrating how impacts could be explicitly quantified, modelled and potentially minimised, in the specific case of changing hydrodynamics impacting on specific habitats.…”

“…De Dominicis et al [31] used FVCOM to estimate farfield effects on tides in the Pentland Firth, Scotland, from proposed commercial-scale tidal arrays. Gallego et al [59] and Waldman et al [52] also modeled possible turbine array configurations in the Pentland Firth and the neighboring Orkney waters; these studies compared Delft3D-Flow and MIKE 3 model results. Although the representations of the turbines in the models were different, the farfield effects were comparable.…”

“…WAMIT has been coupled with other models such as MILDwave to model larger-scale effects with feedback between models [64,65]. It has also been used to parameterize an abstraction of wave devices for the MIKE 21 SW model, without feedback [59,66]. Results from WAMIT have been compared with the results from the COMSOL Multiphysics CFD model to characterize the effects of a wave buoy [47].…”

“…Large arrays have not yet been deployed, so even models in realistic settings cannot be calibrated or validated. Comparisons of results between different models have been used in the absence of empirical data [59] or in addition to field measurements [37,47,52]. Visual comparisons of model results (e.g., [49]) and statistical validation (e.g., [48,52,60,70]) have been employed.…”

Understanding the environmental effects of marine energy (ME) devices is fundamental for their sustainable development and efficient regulation. However, measuring effects is difficult given the limited number of operational devices currently deployed. Numerical modeling is a powerful tool for estimating environmental effects and quantifying risks. It is most effective when informed by empirical data and coordinated with the development and implementation of monitoring protocols. We reviewed modeling techniques and information needs for six environmental stressor–receptor interactions related to ME: changes in oceanographic systems, underwater noise, electromagnetic fields (EMFs), changes in habitat, collision risk, and displacement of marine animals. This review considers the effects of tidal, wave, and ocean current energy converters. We summarized the availability and maturity of models for each stressor–receptor interaction and provide examples involving ME devices when available and analogous examples otherwise. Models for oceanographic systems and underwater noise were widely available and sometimes applied to ME, but need validation in real-world settings. Many methods are available for modeling habitat change and displacement of marine animals, but few examples related to ME exist. Models of collision risk and species response to EMFs are still in stages of theory development and need more observational data, particularly about species behavior near devices, to be effective. We conclude by synthesizing model status, commonalities between models, and overlapping monitoring needs that can be exploited to develop a coordinated and efficient set of protocols for predicting and monitoring the environmental effects of ME.

“…The development of tidal industry has made significant progress over the last decades: numerous tidal projects are under way, examples include development in United Kingdom (Pentland Firth, Shetland, Orkney), in France (Ushant, Aldernay Race) and in China (Zhoustan Archipelago) [1]. There also have been considerable advances in numerical models in the recent years, to assess the influence of tidal farms on the environment principally in 2D [2][3][4][5][6][7][8][9][10][11][12]. However, the conclusions of all these studies are site-specific and dependent on device design; thus, the effects of array size will need to be investigated in the site of interest.…”

Towards a Tidal Farm in Banks Strait, Tasmania: Influence of Tidal Array on Hydrodynamics

The development of tidal energy in Australia is still a challenge with few studies performed on the characterisation of the resource, due to the difficulty to acquire data and uncertainties about the influence of this anthropogenic activity on the marine environment. Changes in flow could lead to alterations in sediment transport and have further influence on the marine habitat. A case study in a promising area, Banks Strait (Australia), was created using high resolution 2D and 3D models validated against in situ data to investigate changes to hydrodynamic conditions with two scenarios of tidal farms (100 and 300 turbines). Comparison between 2D and 3D is performed to find the best compromise between model accuracy and computational time for preliminary assessment. Changes to current speed and bed shear stress over a 35 day period were found to be localised around the tidal farms and did not extent more than 7 km from the farm (300 turbines) for both 2D and 3D. The results showed that for near field and far field, 2D models are sufficient to give a first approximation of the hydrodynamic influence of tidal farm deployment on its environment.
