A water balance model was used to simulate the long-term increases in water yield with forest age which are observed in the mountain ash (Eucalyptus regnans) forests of Victoria, Australia. Speciยฎcally, the hypothesis was tested that water yield changes could be explained by changes in evapotranspir

โฆ Synopsis
The effects of afforestation on water yield from catchments are reviewed. In the light of research findings and an assessment of the method currently used in South Africa to determine reductions of water production associated with afforestation, the A C R U agrohydrological model is adapted to account for changes in critical land use related processes as a forest grows in time by incorporation of a dynamic land use information file. First tests with this model on a catchment at Cathedral Peak in the Natal Drakensberg, which was afforested in 1951, indicate that forest hydrological effects can be modelled successfully with a dynamic land use file. Further model development is outlined.

## Abstract The effect of forests on annual water yield is an unresolved central issue in forest hydrology despite years of study. There has been a particular shortage of research in the mountains of arid inland river basins. In the present study, we examined the effects of forests on hydrology usi
