In NSW the Water Management Act (2000) requires water to be specifically allocated for environmental purposes so as to improve river health. Water sharing plans have been developed that establish extractive and environmental shares to river flows. In unregulated river systems this has resulted...

The Namoi river catchment in northern NSW is an important irrigation region. Water resources in this region are increasingly stressed. Both surface and groundwater supplies are overallocated in many areas of the catchment. Management options to reduce allocations in line with available supply...

This paper applies a stochastic dynamic programming framework, incorporating links to hydrological and biophysical models, to assess the economic costs of environmental flows in an unregulated river system in the Namoi Valley of northern New South Wales, Australia. Structural adjustment...

Increasing pressures on water resources and associated cuts in allocation currently threaten many irrigators in the Namoi River catchment. In particular, cuts to groundwater allocation in many zones are expected to have significant negative social and economic impacts. Changed access to...

Decision Support Tools (DSTs) are designed to assist in making more informed management decisions, through prediction of the outcomes from various future scenarios and as an education resource. The many coastal lakes in New South Wales, Australia are areas where DSTs are able to assist in making...
