Notes:
Recognition of the severity of land and stream salinity problems in Australia over the past few decades has resulted in the application of a range of mitigation strategies. In terms of stream salinity management, ground- water interception has proved the most cost-effective strategy, and a number of ground-water interception schemes have now been implemented. In all cases, the scheme design and assessment of feasibility were based on hydrogeological investigations only. This paper presents an analysis of ground-water behavior associated with the Mildura interception scheme, illustrating the development and use of mathematical models of ground-water flow in simulating a range of management options for the mitigation of river salinity. The study found that: over the period of simulation, the interception scheme had been operating below its achievable operational effectiveness, 48 compared to 72 percent; effectiveness could be further enhanced to 80 percent by judicious placement of three additional well fields; and improved irrigation practices in the area would significantly reduce the flow of salt to the river. The modeling approach applies to similar river salinity problems elsewhere.
