Summary on Grant Application Form |

The present project represents a tripartite partnership between the University of Liverpool (UL), the University of Wales, Bangor (UWB) and the University of Aberdeen (UA). The project aims to improve engineering prediction and physical understanding of sediment transport in combined wave and current conditions in the sheet flow regime. The main contribution of UA will be a detailed, strongly-focussed laboratory study of convective sediment entrainment at flow reversal in oscillatory sheet flow. Experiments will be conducted in the 16m oscillatory flow tunnel at Aberdeen in which detailed measurements will be made of the sediment suspension field near times of flow reversal for a range of sheet-flow experiments involving a fine sand. A 3-transducer ABS system will be used to measure time-varying, vertical concentration and size profiles above the sheet-flow layer and 3 CCM instruments will be used to measure time-varying concentration within the sheet-flow layer. The instruments will be deployed at different horizontal locations in the tunnel in order to examine the horizontal variability of the suspension field. The data will be processed by UA and UL and the results will be used to parameterise the temporal and vertical characteristics of flow reversal suspension for inclusion in the numerical models of UL and UWB. The work of UL and UWB is summarised on separate EPSRC EPS(RP) forms.
