Research Aims

The overarching aim of my research is to develop scientifically defensible solutions to a range of practical water resources problems. My recent research has centered on solving the following three problems:

  • Quantifying the impacts of climate change and variability on Australian and international water resources, including on floods and drought;
  • Developing flood estimation methods to handle complex multi-causal floods in urban, estuarine and rural catchments; and
  • Improving hydrological (rainfall-runoff) models to better understand the role of data errors and non-stationarity, and quantifying prediction uncertainty

Consulting and Contract Research

During certain times of the year I am available to work on small or large consulting and contract research projects. Recently I have undertaken consultancies for the BMT WBM and the NSW Office of Environment and Heritage, and contract research projects for Geoscience Australia, the CSIRO and the West Australian Water Corporation.
