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.
Rain-impacted 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.
Discourse on detachment and
transport of coarse material
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. (For information on the USLE-M follow the USLE-M pathway)
A version of the Agricultural Non Point Source Pollution model (AGNPS) that uses the USLE-M instead of the USLE is known as AGNPS-UM (Software can be downloaded by following the USLE-M pathway)
My work has also included the development of the mathematical form of the rainfall intensity - kinetic energy relationship used in models like the Revised Universal Soil Loss Equation
