Title: Upper Yarra Reservoir Thomson Inlfow Experiment Data Report Authored by: Dallimore, C., Lam, C. Abstract:
The Thomson Inflow Experiment was conducted in Upper Yarra Reservoir, Australia, from February 27 â€" March 3, 2006. The aim of the experiment was to determine the transport times and dilution of the regulated Thomson inflow to the offtake at the dam wall.
To achieve these goals, the following instruments were employed: Lake Diagnostic System (LDS), Fine Scale Profiler (FProbe) and the Fluoroprobe. FProbe/Fluoroprobe profiling stations were distributed across the entire reservoir. The Thomson inflow was initiated after one day of sampling and remained on for the duration of the experiment.
The results show that due to the temperature of the inflow the flow was constrained in the thermocline. This drastically reduced the dilution of the inflow with an observed dilution rate of between 3 and 6.
The dilution of the inflow is heavily dependant on the inflow temperature and because this temperature can be controlled by varying the offtake depth in the Thomson Reservoir there is a large scope for the improvement of the dilution rate by modifying operational management of the reservoirs.
