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 for situations in which the bed comprises a mixture of sand grain sizes. The contribution of UWB is, firstly, to extend its existing, intra-wave, numerical sand transport model to represent grain size mixtures and also account for the effect onthe transport rate of 'convective' sediment entrainment events at flow reversal; and, secondly, to develop a new, two-layer, numerical sand transport model in which the lower layer represents the high-concentration sheet flow region between the stationary bed and the outer suspension layer. Both models will be validated using existing data, and also new data obtained by UA/UL, in the oscillatory sheet flow regime. Results will be obtained from both models over wide parameter ranges of practical engineering importance, these will be intercompared with results from complementary UL models. The final predictions for the sediment transport rate will be presented in the form of tables/graphs suitable for practical use and, in addition, simplified algebraic parameterisations of the results will be developed. The work of UL and UA is summarised on separateEPSRC EPS(RP) forms.
