Research project- Experimental and analytical investigation of motions in the near shore regions of lakes and reservoirs.
Supervisor: Prof John Patterson
Associate Supervisor: A/Prof Chengwang Lei
In lakes and reservoirs, as the result of incoming solar radiation and surface cooling, there are uniform heat fluxes between the air and the water column. However, in near shore regions where the height of the water column is shallow, the water column heats or cools faster than that of deeper regions, causing a horizontal temperature gradient. This gradient contributes to natural convection flow, which exchanges nutrients and pollutants between near shore and off shore regions.
In shallow water regions most of the radiation reaches the lake or sea bed. The solar radiation is absorbed by the surface and then is re-emitted. Although the effect of thermal forcing on shallow water regions has been a subject of previous studies, my research will examine in more detail the interaction between the re-emitted heat flux (which causes potentially unstable boundary conditions), the stably stratified temperature distribution and the effects of topography.
I will focus on analytical approaches, scaling analysis and experimental verification of the resulting scales for a diurnal thermal forcing model.
