- Abstract
The Darling Range Catchment Model (DRCM), a physical-process type hydrologic model, uses forest leaf area as a parameter in the processes of interception of rainfall, and transpiration. The leaf area is correlated with a quantity derived from Landsat data, which is called 'greenness'. Statistical analysis has been used to estimate greenness in terms of the number of years since logging and burning occurred, the mean rainfall, the vegetation-complex type, and whether or not dieback disease is present. Application of the resulting 'greenness model' in the DRCM will allow (a) improved calibration of the catchment model for periods of stream gauging records, (b) evaluation of stream yield under prevailing forest management, and (c) evaluation of alternative forest management strategies under certain conditions.
