Northern Victoria's irrigators use a substantial portion of water from the Murray-Darling Basin, which is under mounting pressure to satisfy competing economic, social and environmental needs for water in the face of climate change. Up to 20 per cent of this water may be on-farm surface runoff and deep percolation, with poorly known spatial distributions. This project will provide reliable temporally and spatially distributed information on surface runoff and deep percolation for Northern Victoria irrigation regions. This will inform decisions which improve water use efficiency, agricultural productivity and environmental values through optimisation of irrigation infrastructure and by better management of groundwater resources and salinity.

北方维多利亚的灌溉者使用的水很大一部分来自默里-达令盆地，面对气候变化，该盆地面临越来越大的压力，需要满足相互竞争的经济、社会和环境对水的需求。其中多达20%的水可能是农田地表径流和深层渗滤，空间分布情况知之甚少。该项目将为北方维多利亚灌区提供可靠的地表径流和深层渗漏的时空分布信息。这将为通过优化灌溉基础设施和更好地管理地下水资源和盐度来提高用水效率、农业生产力和环境价值的决策提供信息。
