Geophysical Surveys to Monitor and Evaluate Environmental Management Initiatives

Clark’s Floodplain, Bookpurnong, South Australia represents a pilot investigation site from which the outcomes will direct management of the larger 17,700 hectare Chowilla Floodplain system, one of six icon sites identified under the Living Murray Initiative. At Clark’s a number of technologies are being trialed including fresh water injection, saline water extraction and artificial surface flooding. The investigations across the sites are measured for success using a variety of vegetation health assessments and supported by investigations into water processes including numerical modeling, soil analysis, ground and surface water monitoring, and a suite of geophysical surveys (EM31, land and in-river TEM, and airborne FDEM and TEM).
