Abstract

Canadian Forest Service in collaboration with CSIRO Forestry and Forest Products and CALM Science of WA participated in Project Vesta forest fire behaviour experiments. During the 1998 experiments 3 m vertical flame temperature profiles were measured in selected fire plots in either the 8 or 19 year old fuel with sparse understorey shrubs. In the 1999 experiments temperature profiles were measured in both the McCorkhill site (dense shrub understorey, which may be up to 2 m tall in the older aged fuels) and the Dee Vee sites (sparse understorey shrubs less than 1 m tall). Also, during these experiments up to 28 thermocouples attached to data loggers (thermologgers) were used to measure flame arrival time and temperature at ground level in a predetermined grid pattern throughout the 200 x 200 m fire plot. These data were used to determine head fire width, rates of spread, flame residence time and flame depth. Temperature profiles were measured in 3 different fuel ages burning simultaneously while the thermologgers were located in 2 different fuel ages. A video camera fire proof box was located in the centre of the fire plot to record flame characteristics, spotting and fire brand behaviour. This paper illustrates the instrumentation of the fire plots with temperature profile towers, thermologgers and the in- fire camera box. Illustrated examples of the data collected are shown in graphs and plots but to date the analysis is incomplete.
