Data of changes in precipitation and evaporation as computed from the GISS GCM for three scenarios of transient levels in trace gas concentration were used as input into the runoff‐climate model of Wigley and Jones to estimate changes in annual runoff regimes for three regions in Australia: Murray‐Darling (south‐east), Lake Eyre (central), and Timor Sea (northern) Drainage Divisions. All regions were calculated to have significant increases in mean annual runoff regardless of the GISS scenarios, due chiefly to the combination of intense aridity (e.g. low runoff ratios) and substantial changes in precipitation and evaporation as predicted by the GISS GCM. Also, attributes of the runoff‐climate model are related to their applicability and accuracy in runoff prediction.
