Summary:
This EPSRC funded poject 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 UL is to develop new
wave-current sheet flow computer models and
obtain unique oscillatory sheet flow laboratory
data with UA. The UL modelling activities are
divided into simple engineering level and
sophisticated numerical modelling. New and
existing data will be used together with the
sophisticated computer modelling results to
systemise understanding of ' convective'
sediment entrainment events at flow reversal and
the end results will be used in the project by
UWB. The UL engineering level model of the mean
sediment transport component will represent
grain mixtures and be combined with
algebraically parameterised intra-wave period
sediment transport results of UWB to yield a
simple and practical sediment transport formula
suitable for field conditions.
