Near-surface geophysics for informed water management decisions in the APY lands of South Australia

Water Management Projects
The direct humanitarian benefit will be information to local water management decisions about available ground water volume and quantity as well as suggested locations for future well installation.
The South Australian Parliament gave Aboriginal people title to more than 103,000 square kilometers of arid land in the far northwest of South Australia. Rainfall is highly variable and the land is arid to semi-arid. Access to potable water is of critical importance for these remote communities.
Combined nuclear magnetic resonance and time-domain electromagnetic methods will be used to map local aquifers, quantify water resources, locate potential fresh water sources for future well sites and guide informed decisions making regarding water resource management.
The key advantage of a combined TEM/NMR measures scheme is leveraging the unique unambiguous water detection capability of NMR with the fast data acquisition of TEM to reliable detect water and map aquifer geometry entirely non-invasively.
