Summary on Grant Application Form |
|
The purpose of this joint project between Oxford University and Strathclyde University is to develop an efficient numerical method for the calculation of tidal induced currents and pollutant transport processes. This will be achieved using adaptive hierarchical quadtree meshing to refine selectively the spatial resolution of a coastal flow-dispersion model. Particular consideration will be given to the prediction of locally high velocity gradients at the edges of shear layers in eddies and the sharp changes in species concentration that occur at advecting effluent fronts. This will lead to improvements in the calculation of tidal currents in coastal waters and in the representation of steep gradients in effluent fronts. The project will extend the methodology of the inverse flow model already developed at Strathclyde University for non-adaptive rectangular meshes to hierarchical adaptive meshes which alter their cell destinies according to bathymetric and flow gradients. The flow model will be verified against field data, and the species transport model tested for cases involving adection, diffusion and moving fronts. This project will lead to a significant improvement in the numerical modelling of efluent dispersion in coastal waters.
