Current projects

FORMOST 2008-2011. Field ObseRvations and Modelling Of the Sediment Triad. Measurements of hydrodynamics, bed forms and sediment transport, collected in three sedimentary regimes -

1. the Dee Estuary in Cheshire
2. Sea Palling in Norfolk
3. in a large scale flume facility in Holland, are being used to develop and assess sediment transport models

LEACOAST2 The study of shore parallel breakwaters for coastal protection. This project is being carried out at Sea Palling in Norfolk.

FLOCSAM Acoustical and optical backscattering by flocculating sediments. The aim of the project is to study the interaction of light and sound with flocculating sediments and the use of light and sound to study the processes of flocculating sediment transport.

Delta flume.  Measurements and modelling of vortex entrainment over a rippled bed. Formation of bed forms under waves. Measurements of sediment diffusivity under waves.

Dee experiment.  Measurement and modelling of sediment transport in the River Dee estuary.

Research interests

Modelling the interaction of sound with suspended sediments and bed forms, to obtain measurements of the dynamic interacting triad of the flow, the bed and sediment movement, to advance process understanding and improving predictions of regional sediment transport.
