Multi-directional focused wave group interactions with a plane beach
Aerodynamic analysis of a two-bladed vertical-axis wind turbine using a coupled unsteady RANS and actuator line model
Close-packed contra-rotating vertical-axis turbines have potential advantages in wind and hydrokinetic power generation. This paper describes the development of a numerical model of a vertical axis turbine with a ...
A finite volume shock-capturing solver of the fully coupled shallow water-sediment equations
This paper describes a numerical solver of well-balanced, 2D depth-averaged shallow water-sediment equations. The equations permit variable horizontal fluid density and are designed to model water-sediment flow over a ...
Resource characterization of sites in the vicinity of an island near a landmass
Renewable energy technologies are undergoing rapid development, the global aim being to achieve energy security and lower carbon emissions. Of marine renewable energy sources, tidal power has inherent predictability and ...
Spatiotemporal variations in vegetation cover on the Loess Plateau, China, between 1982 and 2013: possible causes and potential impacts.
Vegetation is a key component of the ecosystem and plays an important role in water retention and resistance to soil erosion. In this study, we used a multiyear normalized difference vegetation index (NDVI) dataset (1982-2013) ...
Quasi-two-layer morphodynamic model for bedload-dominated problems: Bed slope-induced morphological diffusion
We derive a two-layer depth-averaged model of sediment transport and morphological evolution for application to bedload-dominated problems. The near-bed transport region is represented by the lower (bedload) layer which ...
Life cycle assessment of the environmental performance of conventional and organic methods of open field pepper cultivation system
Purpose: As the scale of the organic cultivation sector keeps increasing, there is growing demand for reliable data on organic agriculture and its effect on the environment. Conventional agriculture uses chemical fertilizers ...
Performance of non-uniform tidal turbine arrays in uniform flow
Theoretical models suggest that in order to maximise their collective power output, tidal turbines should be arranged in a single cross-stream row and optimally spaced to exploit local blockage effects. However, because ...
