Dr Wendy Timms is a Chief Investigator in the National Centre for Groundwater Research and Training’s Program 1 Innovative Characterisation of Aquifers and Aquitards led by Professor Acworth. Wendy leads a research team on Subprogram 1B Characterising Aquitards and is involved in other research programs through the UNSW Connected Waters Initiative. Aquitard research involves developing accelerated gravity permeameter systems, physical modelling of flow through low permeability sediments and rock, advanced field techniques to identify rapid flow through aquitard windows and leaky bores, applying advanced hydrogeochemical, isotopic to trace leakage through and around aquitards and developing numerical models to interpret field and laboratory data. The accelerated gravity permeameter system will assist in characterizing the hydraulic conductivity of clay aquitards and measurement of soil water characteristic curves for unsaturated sediments through the northern-Murray Darling Basin, in Northern and Western Australia and in Canada. Wendy’s research interests include contaminant transport of salts, trace metals, nutrients and agrichemicals, quantifying sources, sinks and fluxes using hydrochemical equilibrium and transport models such as PHREEQC. Her most recent journal publication focused on transport and retardation of rare earth elements as analogues for radionuclide migration over long time scales.
