Using Airborne Electromagnetic Data To Construct A Sediment Textural Model And Salt Budget For Use In Hydrogeological Applications: A Case Study From New South Wales, Australia

This paper reports on the research to quantify salt budgets and sediment and saprolite textures in a sub-catchment of the Lachlan Catchment, NSW. Data were obtained from airborne electromagnetic (AEM), ground and borehole electromagnetic (EM) data, and laboratory petrophysical and geochemical studies. Algorithms have been derived from statistical relationships between AEM conductivity data, down-hole induction logs and petrophysical attributes. These algorithms are then used in ArcGIS™ software to model the salt budgets and textural distribution model.
