Environmental isotopes (particularly d 18 O, d 2 H, and d 13 C values, 87 Sr/ 86 Sr ratios, and a 14 C) constrain geochemical processes, recharge distribution and rates, and inter-aquifer mixing in the Riverine Province of the southern Murray Basin.

The distribution of 222Rn activities and major ion concentrations show that during low river flows characteristic of the recent drought conditions, the middle reaches of the Murray River, northern Victoria, were a predominantly gaining system at low

Complex groundwater flow systems in confined aquifers that result from geological structures, stratigraphic changes, or the absence of efficient aquitards are difficult to constrain using physical parameters alone. Despite a relatively simple aquifer

Summary A low-salinity (total dissolved solids, TDS, 25,000 mg/L) is marked by a hectometer to kilometer scale transition in TDS concentrations that is not stratigraphically controlled. Rather this boundary represents a mixing zone with the regional

Solutes in saline groundwater (total dissolved solids up to 37 000 mg/L) in the Lake Cooper region in the southern margin of the Riverine Province of the Murray Basin are derived by evapotranspiration of rainfall with minor silicate, carbonate and ha

87Sr/86Sr ratios of groundwater in the southeast Riverine Province of the Murray Basin, Australia are between 0.7107 and 0.7191. The 87Sr/86Sr ratios vary between different subcatchments and generally decline with distance northwards from the basin m

Summary Water table fluctuations and renewal rates based on 3H and 14C concentrations in bores screened within 5 m of the water table were used to estimate recharge rates in five dryland salinity areas in northern Victoria, Australia. Given the resol

A previously-defined flow system is used to investigate REE behavior at different stages along groundwater flow paths in fractured basalt and sedimentary aquifers. Results from this study indicate that REE concentrations and patterns predominantly re

The Tyrell catchment lies on the western margin of the Riverine Province in the south-central Murray Basin, one of Australia’s most important groundwater resources. Groundwater from the shallow, unconfined Pliocene Sands aquifer and the underlying

Systematic variations in Cl/Br ratios together with R 36 Cl values, 14 C activities, and δ 18 O values reflect differences in groundwater recharge and define groundwater flow paths in the Riverine Province of the southeast Murray Basin. In groundwat
