Scientists model risks to Marlborough's main aquiferSUPPLIED Marlborough's Wairau River, from Northbank Rd in the Wairau Valley, west of Blenheim. The Wairau Aquifer is the main groundwater system underlying the Wairau Plain and a source of irrigation, drinking and stock water. He leads several research programmes at Dresden University, in Germany, where his computer flow model of the Wairau River and Wairau Aquifer was developed. His team in Germany could not determine the impact earthquakes had on the Wairau Aquifer. "The modelling gives valuable insights into the storage properties of the Wairau Aquifer," Wohling said.
