Chris Turnadge

Chris is an Adelaide-based hydrogeologist in Land and Water’s Regional Scale Groundwater Analysis team. His research primarily involves the characterisation of various aspects of regional-scale groundwater flow systems. Chris uses a wide range of analytical and numerical tools for groundwater flow system characterisation. These include the interpretation of hydraulic, hydrochemical and isotopic data, including pumping test reinterpretation. Chris is also involved in the quantification of sensitivity and uncertainty of predictions generated by groundwater flow models.

Chris is undertaking a doctorate at Flinders University, in partnership with CSIRO and the University of Colorado Boulder. This research is focused on the use of adjoint state methods for the calculation of state sensitivities of saturated groundwater flow problems. The use of adjoint sensitivities provides opportunities for considerable efficiency gains for ill-posed inversion problems, while also often providing valuable insights into dynamic processes.
