Career Summary

Biography

My expertise lies in wastewater reuse to land, the associated impacts of wastewater quality on soil structure and contaminant export to natural waterways. The ability to maintain soil structure for a woodlot irrigated with municipal effluent of variable chemical composition was the focus of my PhD thesis. The impact of sodium on clay particle behaviour was used as a surrogate for predicting the impact of irrigation/rainfall events (of differing quality) on soil structure comprising different sodium percentages. Wider research interests include integrated water cycle management, contaminant export from non-sewered areas and soil/water interactions and processes.

The Probabilistic Urban Rainfall and wastewater Reuse Simulator (PURRS v7.2), the Model for Urban Stormwater Improvement Conceptualisation (MUSIC v3) and Spreadsheet modelling tools were compared for evaluating rainwater harvesting strategies. Input data included climate files, suggested water demands and time-steps. Models were run with climate data of unequal duration and time-step, which highlighted significant differences between modelled outcomes. Using climate data of equal duration still resulted in major differences. The reasons for these differences are explained as a function of the duration and time-step of climate data, the time-step and diurnal patterns of indoor/outdoor water demand and tank configuration. Results imply that the length and time-step of climate inputs, the distribution and time-step of daily water demand and rainwater tank configuration are significant factors in robustly evaluating mains water savings for a range of Australian climates.
