Summary on Grant Application Form |
When a tidal flow oscillates past a headland, breakwater or narrow-entranced coastal basin, separation-like flow can result and large-scale eddies are frequently produced in the wake. Such eddies can have a significant influence on solute and sediment trapping and are of considerable concern in a range of environmental engineering problems. This eddy structure is highly sensitive to the bathymerty, the driving currents, the tidal period (usually 12 hours), the bed roughness and paramenters defining turbulence. There may be no recirculation zone, a single zone generated in each half cycle or several zones interacting in successive half cycles. Numerical models which in general contain dissipation for stability are notoriously weak in prediciting flow instabilities of this kind and yet these issues have no research effort in this context. In this project an experimental investigation will be undertaken at three different scales for actual and idealised geometries to determine the nature and detailed structure of recirculation zones. The limitations of 3-D ( and 2-D) numerical modelling of the shallow-water equations will be assessed using models recently developed at Bradford and Manchester. Solute will be introduced in the experiments and measured concentrations will be compared with model predictions.
