Modeling tidal stream energy extraction and its effects on transport processes in a tidal channel and bay system using a three-dimensional coastal ocean model

TL;DR: In this article, the authors investigated the impact of the deployment of turbine arrays on sediment dynamics and seabed morphology in the Pentland Firth, Scotland, using a 3D coupled hydrodynamic and sediment transport numerical model.

TL;DR: In this paper, the authors investigate the flow interactions between turbines in a stream energy site with spatially and time-varying tidal conditions using the Actuator Disk (AD) theory.

TL;DR: In this article, a set of field measurements distributed along Chacao Channel is presented for tidal energy resource characterization, including tidal elevations, tidal currents (in space and time), and turbulence.

TL;DR: In this paper, an unstructured-grid coastal ocean model, fitted with a module that simulates tidal energy devices, was applied to simulate the tidal energy extracted by different turbine array configurations and the potential effects of the extraction at local and system-wide scales in Tacoma Narrows and South Puget Sound.

TL;DR: An unstructured grid, finite-volume, three-dimensional (3D) primitive equation ocean model has been developed for the study of coastal oceanic and estuarine circulation as discussed by the authors.

TL;DR: Synthesis of literature pertaining to benthic hypoxia and anoxia revealed that the oxygen budgets of many major coastal ecosystems have been adversely affected mainly through the process of eutrophication (the production of excess organic matter).

TL;DR: In this paper, the authors review features of macroalgal blooms pointed out in recent literature and summarize work done in the Waquoit Bay Land Margin Ecosystems Research project which suggests that nutrient loads, water residence times, presence of fringing salt marshes, and grazing affect macroalgae blooms.

TL;DR: Detailed examination of the effects of pollution inputs, the loss and alteration of estuarine habitat, and the role of other anthropogenic stress indicates that water quality in estuaries, particularly urbanized systems, is often compromised by the overloading of nutrients and organic matter, the influx of pathogens and the accumulation of chemical contaminants.
