Associate Professor Barry Croke

Associate Professor

Associate Professor Barry Croke has a BSc in Theoretical Physics and a PhD in Astrophysics from the University of NSW.

He started working in Environmental Science in 1996, and has been a staff member in the Integrated Catchment Assessment and Management Centre since 1999, and has held a joint appointment with the Mathematical Sciences Institute and the Fenner School of Environment and Society since 2006.

Associate Professor Croke has expertise in modelling a wide range of natural systems, particularly focusing on model development, assessment and uncertainty analysis. He is President-elect of the International Commission on Water Resources Systems within the International Association of Hydrological Sciences, Treasurer of the Modelling and Simulation Society of Australia and New Zealand, and a member of the Editorial Board of Hydrology Research.

Research interests

  • Development of models for prediction of streamflow and water quality, as well as integrated resource management.
  • Prediction of flow at ungauged sites, which requires techniques for predicting hydrologic response based on catchment attributes such as topography and land use. This involves development of models suitable for such work, as well as exploring the relationships between model parameters and key catchment attributes.
  • Modelling water quality including estimation of sediment, nutrient and pathogen exports. 
  • Investigating model response to uncertainty in parameter values and input data through sensitivity analysis. This is an important component of model development due to the sparse nature of environmental datasets.
  • Modelling carbon fluxes for evaluation of carbon offsets.
