Summary on Grant Application Form |
|
Estuarine and coastal suspended sediment dynamics is a complex phenomenon, with the sediment undergoing a series of processes such as erosion, deposition, advection and diffusive transport. Despite a large amount of effort being devoted to developing and refining numerical sediment transport models, there is still a lack of accuracy in predicting sediment concentration distributions.The main aim of this project is to investigate how physical process based (ie deterministic) numerical models can be integrated with data dependent ANNs to predict the sediment fluxes in estuarine and coastal waters. A new sediment transport modelling tool will be developed using a combined deterministic and ANN approach. In this model the transport of sediment within the water column will be described according to physical lawas, ie based on the advective-diffusion equation, and this equation will be solved using the finite volume method. The erosion and deposition of sediments and, in particular, the criteria for the initiation of motion of sediment, will be simulated using ANNs. The model will be tested against laboratory experimental data measured for a model harbour and then applied to predict sediment fluxes for the Humber and Ribble Estuaries.
