Summary on Grant Application Form |
|
Hydraulic flows past topographic changes in the depth or width of a channel are characterised by properties of the flow such as the mean velocity only being a function of the topographic perturbation. Flows in which these properties differ upstream and downstream of the maximum topographic perturbation are known as hydraulically controlled flows and are ubiquitous in large and smale scale environmental flows. A classic example is exchange flow in a contraction; this contraction could be a dam wier or the Straits of Gibraltar. Hydraulic theory for flow through contractions has extensive application, however it is limited in that dispersion due to waves is ignored and it is by in large steady. This then leads us to ask how do hydraulically controlled flows develop and what is the preferred state when multiple hydraulically controlled states are possible? This research aims to address these questions by investigating unsteady weakly-dispersive hydraulic flows. Using this approach we aim to address to determine if hydraulic solutions are a valid approximations to reality, and secondly what effect the initial state has on possible steady hydraulic solutions.
