The benefits of ecosystem services to cities are well documented; for example, water-sensitive urban design to mitigate stormwater flows and purify run-off, the cooling benefits provided by tree shade, and psychological benefits of urban greening. Cities...

Experimental testing of physical turbines, often at a smaller scale, is an essential tool for engineers to investigate fundamental design parameters such as power output and efficiency. Despite issues with scaling and blockage which are caused by limitat...

This study proposes the design of a tidal turbine station keeping system based on the adoption of a tensioned mooring system. Damping is introduced to investigate its effect on the reduction in the peak load experienced by tidal turbines during their ope...

Existing installations of tidal-stream turbines are undertaken in energetic sites with flow speeds greater than 2 m/s. Sites with lower velocities will produce far less power and may not be as economically viable when using ?conventional? tidal turbine d...
