New groundwater flow modelling developed by the UNSW Connected Waters Initiative team aims to help provide a better understanding of the dynamics of the alluvial aquifer in the Maules Creek Catchment using an integrated approach to modelling catchment water resources.
As the world awakens to the harsh realities of climate change and food insecurity, much of it apparently remains oblivious to a looming global water crisis, which climate change will aggravate by making rainfall more erratic in many regions.
Regrettably, politics has always dominated decisions about water in this country which suggests that water restrictions are likely to be more severe than they need to be for the foreseeable future.
The answer to this question is, unfortunately, easy but not very gratifying.
Following encouraging results from a preliminary groundwater investigation, a second more extensive, groundwater resource investigation commenced in November 2006 to quantify the groundwater resource potential of the Hawkesbury Sandstone aquifers in western Sydney.
Many countries face severe water scarcity, either as a result of a lack of available fresh water, or due to a lack of investment in water infrastructure, such as dams and reservoirs. What makes matters worse is that this scarcity predominantly affects developing countries where the majority of the world's under-nourished people - approximately 840 million - live.
Over-allocation of water resources remains a serious impediment to sustainable water use. The environmental health of too many of our river systems is under stress and the contest for access to water is increasing.
Seawater use taps an unlimited resource that is not climate-dependent. Because of its plenitude and reliability, seawater is likely to be used increasingly as a source of security in vulnerable water systems. However, its energy use could have unwanted feedback to global warming.
Recycled water options for both non-potable and potable (drinking water) use should be among the options considered on their merits as mechanisms that have potential to reduce the long-term demands on the resources of our river and groundwater systems.
The challenge of feeding the world and providing enough water to facilitate this is daunting, given that the consequences of failure will have profound ramifications for rich as well as poor countries.
