Abstract (sommario):

AbstractWater sampling at springs that are a part of the Freeling Spring Group, South Australia, was used along with electrical resistivity imaging (ERI) data to evaluate the sources and pathways for groundwater to the springs and to find evidence of mixing between the Great Artesian Basin (GAB) aquifer system (Algebuckina Sandstone, Cadna-owie Formation and lateral equivalents) and waters from the adjacent mountain block basement (MB) aquifer. Five springs and a well were used to evaluate spring chemistry; multi-electrode resistivity data were collected along three orientations over the Freeling Spring site. The resistivity data indicate three independent electrically conductive curvilinear features connected to the spring. These features are evidence of mixing at the spring vent similar to what would be predicted from traditional hydraulic flownets. The chemistry of the spring water samples indicates that the water emanating from the Freeling Spring Group is a mixture of waters from both the GAB and the MB aquifers, supporting the geophysical evidence. The data suggest mixing occurs along a fracture in the body of the MB and porous media flow in the GAB beds, but the system is dominated by the GAB flow, which provides approximately 90% of the discharge.

Abstract (sommario):

In semi-arid regions, groundwater resources play a crucial role in all economic, environmental, and social processes. However, the occurrence, movement, and recharge of these hidden and valuable resources vary from place to place. Therefore, better management practices and mapping of groundwater recharge potential zones are needed for the sustainable groundwater resources. For an example, groundwater resources in Willochra Basin are vitally important for drinking, irrigation, and stock use. This study shows the significance of the application of three decision-making approaches, including multi-influencing factor, analytical hierarchy process, and frequency ratio techniques in the identification of groundwater potential zones. A total of seven criteria, including lithology, slope, soil texture, land-use, rainfall, drainage density, and lineament density, were extracted from conventional and remote sensing data sources. The parameters and their assigned weights were integrated using Geographic Information System (GIS) software to generate recharge potential maps. The resultant maps were evaluated using the area under the curve method. The results showed that the southern regions of the Willochra Basin are more promising for groundwater recharge potential. The map produced using the frequency ratio model was the most efficient (84%), followed by the multi-influencing factor model (70%) and then the analytical hierarchy process technique (62%). The area under the curve method agreed when evaluated using published weights and rating values.

Abstract (sommario):

An approach of reporting long-term trends in groundwater extraction and baseflow impacts in the Murray-Darling Basin (MDB) in south-eastern Australia was developed and tested. The principal aim of the framework was to provide early warning of any potential adverse impacts from groundwater extraction on environmental releases of surface water for baseflow, support adaptive management of these impacts, and highlight those areas which may benefit from conjunctive water management. The analysis showed that there is no current decadal trend in the annual aggregate groundwater extraction volumes or stream impact across the non-Victorian MDB, with much of the interannual variability being related to rainfall. Despite this, increasing volumes of environmental releases of water for baseflows in some river valleys are being required to replace the stream depletion caused by historical patterns of groundwater extraction established before 2003. Two valleys were identified for which there may be insufficient surface water storage to release water to substitute stream losses to groundwater and still support ecosystems during dry periods. The increasing trend in extraction since 2003 in one of the units has significantly increased the risk in that valley. The reporting framework was shown to be effective for alluvial groundwater systems connected to regulated rivers.

Abstract (sommario):

Hypotheses to explain the source of the 1011 tons of salt in groundwaters of the Murray Basin, south-eastern Australia, are evaluated; these are (a) mixing with original sea water, (b) dissolution of salt deposits, (c) weathering of aquifer minerals and (d) acquisition of solutes via rainfall. The total salinity and chemistry of many groundwater samples are similar to sea-water composition. However, their stable isotopic compositions (δ18O= –6.5 ‰; δ2H = –35) are typical of mean winter rainfall, indicating that all the original sea water has been flushed out of the aquifer. Br/Cl mass ratios are approximately the same as sea water (3.57 x 10-3) indicating that NaCl evaporites (which have Br/Cl<10-4) are not a significant contributor to Cl in the groundwater. Similarly, very low abundances of Cl in aquifer minerals preclude rock weathering as a significant source of Cl. About 1.5 million tons of new salt is deposited in the Murray–Darling Basin each year by rainfall.The groundwater chemistry has evolved by a combination of atmospheric fallout of marine and continentally derived solutes and removal of water by evapo-transpiration over tens of thousands of years of relative aridity. Carbonate dissolution/precipitation, cation exchange and reconstitution of secondary clay minerals in the aquifers results in a groundwater chemistry that retains a ‘sea-water-like’ character.

Abstract (sommario):

Improving irrigation efficiency (IE) is an approach used globally to help meet competing demands for water and facilitate reallocation of water between sectors. In the Murray–Darling Basin in Australia, the Australian government has invested heavily in IE projects to recover water for the environment. However, this approach has been seriously questioned, out of concerns that improved IE would reduce irrigation return flows to rivers and therefore offset water recovery. In this study, we use a water balance model to assess the impact of the IE projects on return flows and highlight sensitivities and uncertainties. The model enables the impact on return flows to be assessed on specific IE projects and regional characteristics. Overall, reductions in return flows are estimated to be less than 20% of the total proposed IE savings. The history of IE in the southern MDB has meant that most of the current reductions are in ground return flows. Our estimate is much lower than two previous studies, mainly due to different assumptions being used on groundwater connectivity between irrigation areas and major streams. While the IE projects significantly reduce seepage to groundwater (with off-farm and on-farm projects reducing seepage by 19% and 53% of total savings respectively), not all seepage reductions will translate to a reduction in ground return flows to rivers. A lower estimate is consistent with existing monitoring and groundwater modeling studies. In this paper, the study results are discussed in a broader context of impacts of IE projects on volumes and salinity of streams and groundwater resources.

Abstract (sommario):

Addendum on back page. Includes bibliography. Groundwater levels within the Willunga Basin, South Australia, are declining due to excessive extraction of water for irrigation purposes. An alternative source of water is needed to supplement the declining levels to ensure the sustainability of the groundwater system. A model was developed to evaluate the potential for using aquifer storage and recovery in conjunction with the surface storage of streamflow as a possible alternative water source. The application of this model to the largest catchment in the Willinga basin shows that sufficient streamflow is available to reverse the current overexploitation of the groundwater system.

Bibliography: 80-82. Electronic publication; full text available in PDF format; abstract in HTML format. The process of calibrating a numerical model is examined in this thesis with an application to the flow of groundwater in the Willunga Basin in South Australia. The calibration process involves estimating unknown parameters of the numerical model so that the output obtained from the model is comparable with data that is observed in the field. Three methods for calibrating numerical models are discussed, these being the steepest descent method, the nonlinear least squares method, and a new method called the response function method.

Abstract (sommario):

The Wybong Creek catchment is located in the upper Hunter Valley of New South Wales, Australia, and contains award winning beef and wine producing operations. Solute concentrations in Wybong Creek are often too high for irrigation use, however, with previous research showing that the saline and Na-Cl dominated water discharged from Wybong Creek decreases water quality in both the Goulburn and Hunter Rivers into which it flows. This study therefore aimed at identifying the source of solutes to the Wybong Creek catchment and the processes which cause salinisation of surface water, soil (regolith) and groundwater. Surface water was sampled at ten sites along Wybong Creek over three years, while groundwater was sampled from most of the bores and piezometers occurring in the Wybong Creek valley. Surface and groundwater in the upper catchment were dominated by Na-Mg-HCO3. Ratios of 87Sr/86Sr and cation/HCO3 indicated these facies were due to silicate weathering of the Liverpool Ranges, with localised groundwater bodies recharging in the Liverpool Ranges and discharging in the upper Wybong Creek valley. Wybong Creek became saline, and Na-Mg-Cl dominated in the mid-catchment area, with salinity doubling between the 55 and 60 km sample sites on some dates. Changes in surface water chemistry occurred independently of surface water input from tributaries, with abrupt salinity increases within a pool between these sites attributed to groundwater input via fractures beneath the Creek. One of two salt scalds in the Wybong Creek catchment also occurs adjacent to this stretch of river. A field site was established at the mid-catchment locality of Manobalai, therefore, in order to constrain the relationship between surface water, regolith and groundwater salinity. Ten piezometers were established at Manobalai, including three piezometer nests. Most regolith at Manobalai was found to be non-saline, including that within the salt scald, with the most saline and Na-Cl dominated regolith samples occurring in some of the most moist and coarse sandy/gravel layers. Groundwater sampled from piezometers installed in the holes drilled for regolith samples had salinities up to 20 times higher than the regolith on a per weight basis, and were similarly dominated by Na-Cl. A lack of carbonate and sulfate minerals within the soils and no indication of Ca-Mg/HCO3- SO4 dominated facies within alluvial soil solutions indicated groundwater did not evolve from rainwater to Na-Cl dominated facies while infiltrating the regolith. Groundwater samples from Manobalai were instead found to be amongst the most fresh and the most saline within the Wybong Creek catchment, and changed salinity abruptly down-gradient along a transect. Groundwater flow occurred through fractures in the Narrabeen Group sandstones and conglomerates, with vertical groundwater flow via fractures causing abrupt changes in salinity. Ratios of Na/Cl, Cl/Br and 87Sr/86Sr indicated saline groundwater at Manobalai and in the lower catchment was influenced by a marine endmember and halite dissolution. A poor relationship between salinity and d18O indicated this marine endmember was not evapoconcentrated rainwater. The occurrence of saline surface and groundwater in the Wybong Creek catchment was instead attributed to discharge from the regional groundwater system occurring in the Wittingham Coal Measures, with the abrupt increases in salinity at Manobalai indicating mixing between local, intermediate and/or regional groundwater systems. Salinity is likely to function similarly to this in the rest of the Hunter Valley also. The occurrence of salinity in both the Hunter River and Wybong Creek catchments is a naturally occurring phenomenon with salinity mitigation difficult due to the regional extent of the saline groundwater systems. Living with salt strategies are therefore recommended, such as limiting irrigation using both saline and fresh water and continuing with restrictions on saline discharge from coal mines.

Abstract (sommario):

Abstract New South Wales has more than 100 years of history of water licensing and allocation. This chapter reflects on the approach to water allocation in the current groundwater sharing plans, including general principles and underlying reasoning for application elsewhere. Focus is on groundwater-specific issues for transition from open to regulated access, while embedded within broader water regulations and connections to surface water management. Water allocation is built around water sharing plans that determine extraction limits, with community consultation. Water rights are differentiated in terms of water sources and priority, separated from land ownership, and from time-varying water allocations, subject to available water determinations. Both water entitlements and allocations can be traded, with rules governing impact of trade. Water sharing plans are state-level instruments explicitly connected in applicable regions to the Commonwealth-level Murray-Darling Basin Plan and associated extraction limits. Compliance is based firstly on metering of water extractions. Future prospects are also discussed.
