This award will support collaborative research between Prof. H. James Simpson of Columbia University, and Dr. Graham B. Allison of the Adelaide Laboratory of the Commonwealth Scientific and Industrial Research. The investigators will employ stable isotope analysis of river water and agricultural drainage to investigate how much water is lost by transpiration, and how much by evaporation, from the irrigation network in Australia's Murray River system. The project combines the expertise of the investigators, who are both experts in water composition analysis using radioactive techniques. While this research could lead, in the short term, to the improvement of the water and salinity budgets of Australia's important Murray River agriculture zone, it should also demonstrate the general potential of stable isotope methods in management of large irrigation networks.

该奖项将支持H。哥伦比亚大学的詹姆斯·辛普森和格雷厄姆博士B。联邦科学和工业研究阿德莱德实验室的艾莉森说。研究人员将对河水和农业排水进行稳定同位素分析，以调查澳大利亚墨累河系统灌溉网络中有多少水因蒸腾而流失，又有多少水因蒸发而流失。该项目结合了调查人员的专业知识，他们都是使用放射性技术进行水成分分析的专家。虽然这项研究可以导致，在短期内，澳大利亚的重要墨累河农业区的水和盐度预算的改善，它也应该证明稳定同位素方法在管理大型灌溉网络的一般潜力。
