This project commenced in 2002 to monitor DD across a range of irrigated cropping lands in the upper Murray Darling basin. At its peak, there were 11 sites where lysimeters were installed (all but one in commercial, irrigated cotton fields) giving a total of 33 lysimeters with one near the head ditch, mid field and tail ditch in each field. This monitoring has continued but the project has widened to consider the related aspects of change in root zone salinity, whether DD (or other surface water events) are linked to groundwater rise, and most recently rootzone salinity change with new irrigation technologies aimed at improved WUE. This paper will present results from the five main subject areas of the project: (i) deep drainage, (ii) WUE and soil salinity implications with a lateral move, (iii) DD leachate water quality, (iv) resistivity imaging showing deep "pools" of water and salt below irrigated fields and (v) links of surface irrigation with groundwater response.
