Impact of Land Use Change on Hydrology
Abstract
In many parts of Australia land use change is occurring on a scale that has not been seen in recent history. This paper presents a methodology that estimates the effects of land use change on the hydrology of south-western Victoria and south-eastern South Australia. The approach draws in the available regional data sets, local expert knowledge and existing numerical models. The unit of modelling is the subcatchment ranging in size from 150km
2. to 1500km
2. Two complementary models are used to simulate changes in water balance under a change in land use. The paper presents the modelling approach, assumptions regarding catchment water balance and some illustrative results.
