Improving the Prediction of Soil Losses from Disturbed and Rehabilitated Land in Mining Operations at Sub-Catchment Scale
The legislation regarding erosion and sediment control management in Queensland is undergoing updates, necessitating the justification of management strategies. The purpose of this study is to improve our knowledge of the sediment delivery ratios and the related governing factors in catchments affected by open-cut mining operations. Its goal is to discover the elements that influence sediment deposition and trapping, and then utilise those insights to validate and calibrate results from catchment-scale soil erosion models.
Yasanga completed his Bachelor of Engineering (Honours) in Earth Resources Engineering from the University of Moratuwa, Sri Lanka. With a focus on Mining and Minerals Engineering, specialisation in Remote Sensing and GIS, and industry experience, Yasanga's research interests now include mining engineering, geotechnical engineering, remote sensing and GIS, and mine rehabilitation.
Industry
Yasanga worked as a QA/QC Engineer on a major tunnelling project in Sri Lanka, focusing on geotechnical studies. After project completion, he became a GIS Analyst, collaborating with government bodies on projects and reporting using drone technology. Later, Yasanga joined the University of Moratuwa as a lecturer (temporary/contract), conducting R&D in RS and GIS for the mining industry.
