Assessing the Potential for Algal Blooms in Clear Water Phase Tropical Rivers

Associate Professor George Ganff, from the University of Adelaide studied the rivers of northern Australia and particularly those in the Top End of the Northern Territory which are subject to major seasonal changes in flow and inter-annual variability. During the dry season, spring water maintains flow with different water chemistry from the rainfall run-off that constitutes wet season flow.

Delivering Sustainability through Risk Management

Milestone Report - August 2004

Any future expansion of irrigated agriculture in Australia is likely to occur in northern Australia. The region of Australia north of the tropic of Capricorn has abundant water resources — over 60% of the nations surface water run-off (NLWA 2001). However, there are concerns that in the rush to develop this new bonanza we will simply make the same mistakes that plague existing irrigation systems. These include: water logging, salinization, soil acidification, erosion, (more)...

Wastewater recycling in nurseries

National Program for Sustainable Irrigation Fact sheet 2005/3

Reducing water run-off, minimising nutrient leaching and optimising irrigation efficiency are major challenges for the nursery industry. A comprehensive review of Australian and international research programs covering all aspects of waste water management in nurseries has been carried out by Horticulture Australia Limited (HAL) - a funding partner for the National Program for Sustainable Irrigation. The review identified useful resources for the industry and best practice in (more)...
