Broken Hill managed aquifer recharge project: Aerial groundwater surveying video
This video shows aerial surveys being done as a part of the Broken Hill managed aquifer recharge project.
The project is identifying groundwater resources and aquifer storage options that will potentially secure the town's future water supply.
V/O: This strange looking activity is part of an important mission, securing a sustainable water supply for Broken Hill.
The operation commissioned by the Department and carried out by experts from Geoscience Australia aims to find precious groundwater and aquifer storage options.
Two helicopters scan the desert landscape, the frames suspended below transmitting and receiving electromagnetic signals.
The signals show variations in the electrical conductivity of the ground and help map aquifers, aquitards, salinity and underground geological features.
The surveys from the sky are being followed up with borehole drilling and studies on the ground.
The Broken Hill Managed Aquifer Recharge project will potentially secure the city's future water supply. It will also allow water lost to evaporation from Menindee Lakes to be returned to the environment.
