This project has demonstrated that incorporating groundwater chemistry into hydrogeological investigations is essential and stresses the need for continuous and rigorous monitoring of water chemistry, because it provides information about how changes in water management will affect both surface water and groundwater quality in the long term.
Stalagmites have several characteristics that make them ideally suited to reconstructing past climates and environments.
The National Water Initiative (NWI) requires all currently overallocated and overused surface and groundwater systems to be returned to environmentally sustainable levels of extraction. It also requires other less-stressed systems to be maintained at an environmentally sustainable level of use.
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.
Groundwater levels and aquifer storage
There are two common mistakes often made when calculating how much groundwater storage levels have changed.
