“The Times They Are a-Changin” - Factors affecting observed spatio-temporal patterns in ground conductivity along the Murray River Floodplains, in south eastern Australia.

The recent advent of calibrated airborne EM systems, coupled with effective ground-based calibration procedures and more robust inversion tools that can account for system geometry, have given added impetus to their deployment as tools to aid the quantitative monitoring of variations associated with floodplain ecosystems, and in particular processes connected with surface water and groundwater interactions. This also has implications for understanding the consequences of floodplain management.
