Summary on Grant Application Form
The programme consists of three elements. Firstly, the application of a numerical model of aeolian bed-load transport to investigate transport in a fluvial environment. Successful pilot experiments have already been performed. The model includes direct calculation of the flow field and thus transport is self-stabilising in he modified flow. Secondly, the application and development of a second numerical model to investigate the formation of surface armour on a bed subjected to bed-load transport. This model calculates the erosion and deposition of individual grains accordingly to conditions or rules specified by the user eg setting requirements for a grain to come to rest in a particular location. Thirdly, to couple these two models so that the bed-load model calculates the erosive capability of the flow on the bed and the downstream transport of moving grains and that the surface model responds by armouring or reducing the amount of sediment available for transport. The interactive use of these models will provide a reasonably complete numerical description of the bed-load transport system. Detailed comparison with experimental data (Tait and Willets, 1992), will provide a stern test of the simulation. It is emphasised that the models are self-stabilising and have only a limited reliance on empirical results. Thus the programme promises important physical insight into the processes which determine equilibrium of bed-load transport.
