Adjunct Associate Professor of Land and Environment
RESEARCH HISTORY (Brief)
After joining the Commonwealth Scientific and Industrial Research Organisation (CSIRO), I initially worked on splash erosion but then moved on to erosion by rain-impacted flow which became my main research focus.
flow is important in interrill and sheet erosion. My work on the use of the product of runoff rate and
rainfall intensity in modelling interrill erosion bacame the basis for the USDA's Water Erosion Prediction
Project (WEPP) interrill model released in 1995.
Also, Sediment transport in rain-impacted flow
causes particles to move downstream at rates that vary with their and size
density. This has implications with respect to the loss of
nutrients, pollutants and carbon from sheet and interrill
I have also worked on the development of hydrologically based erosivity indices for use in empirical erosion models
like the USLE leading to the development of a NEW
version of the USLE known as the USLE-M.
