Analysis of the storm event rainfall and runoff data and other physical data from the undisturbed Geebung Creek catchment shows that its hydrologic behaviour is well described by the variable source area concept. Runoff is believed to occur mainly from saturated source areas that are fed by rapid subsurface flow from upslope. O'Loughlin's theoretical steady-state saturation zone model has been applied to the catchment to identify the size and location of zones of saturation in the landscape under a range of wetness conditions and field observations confirm the general predictions made by the model. Linkage of the results from this model with a simple rainfall—runoff model provides a means of modelling the hydrologic response of the catchment to precipitation in terms of the dynamic expansion and contraction of the saturated source areas. The results of the rainfall—runoff simulation on the Geebung Creek catchment are very good, indicating that this methodology may have considerable potential for evaluating the impacts of land use change on the hydrology of certain types of catchments, at the process level.
