Abstract
Widespread clearing of native vegetation has dramatically increased recharge in the Mallee region by up to two orders of magnitude. The resultant rising water tables have caused land salinisation problems in low lying areas and, in the long term, will increase saline groundwater inflows to the River Murray with a consequent rise in river salinity. Computer modelling suggests that, 50 years after the water table begins responding to the increase in recharge, an increase of 70 Electrical Conductivity (EC) units in river salinity will occur at Morgan. Broadscale revegetation in strategic areas adjacent to the river will reduce saline groundwater inflows, and the economic and social aspects of this measure should be investigated.
