Application of Macaque and 3PG+ in CAT catchment- scale hydrological models: limitations and opportunities

Process-based models that incorporate the major environmental influences on the growth and water use of forests and vegetation, and on the consequential effects on streamflow, allow us to explore the likely effects of the change in forest structure on resulting catchment water balances. Results from these models are being used, to underpin the development of water and forest management strategies and policies. In this paper we describe and discuss the application of two catchment-scale process-based models, their assumptions and limitations, and provide some guidance for the further development and future application of these models.
