WebJul 13, 2015 · Grass senescence, or grassland curing, is a dynamic process in which grass fuels transition from a live to dead state and, in turn, influence fire dynamics. In the present study we examined the process of curing with specific consideration of changes in fuel structure that will affect potential fire behaviour. Our sampling protocol expanded the fuel … WebJun 16, 1997 · The fire spread rate was established based on the grassland fire behaviour field experiment and the Rothermel model. Finally, according to the spread patterns of large-scale grassland fires, meteorological and remote sensing (RS) data were used to simulate the propagation process of a grassland fire.
