Likely recharge to permanent groundwater beneath future rehabilitated landforms at Ranger uranium mine, northern Australia

The magnitude of recharge beneath rehabilitated landforms at former mine sites is one of many variables required for a comprehensive assessment of potential future environmental impacts of those sites. The magnitude of net groundwater recharge that may occur on the rehabilitated Range Uranium Mines landform is estimated to be of the order of 2–5% of the incident rainfall, that is, about 25 to 65 mm/a.
