Hillslope Erosion and Post-Fire Sediment Trapping at Mount Bold, South Australia
42 Wildfire and Water Quality: Processes, Impacts and Challenges (Proceedings of a conference held in Banff, Canada, 11–14 June 2012) (IAHS Publ. 354, 2012). Hillslope erosion and post-fire sediment trapping at Mount Bold, South Australia ROWENA MORRIS1,2, DEIRDRE DRAGOVICH3 & BERTRAM OSTENDORF1 1 Earth and Environmental Science, PMB 1, Glen Osmond, University of Adelaide, South Australia 5064, Australia [email protected] 2 Bushfire Cooperative Research Centre, Level 5, 340 Albert Street, East Melbourne, Victoria 3002, Australia 3 School of Geosciences, Madsen Building (F09), University of Sydney, New South Wales 2006, Australia Abstract Successful placement of sediment traps requires an understanding of how hillslope morphology influences erosion. Following the 2007 Mount Bold wildfire, in South Australia, a 1 in 5 year rainfall event resulted in the failure of many sediment traps due to substantial sediment movement within the reservoir reserve. This study assesses how hillslope morphology can influence post-fire surface erosion and the subsequent appropriate placement of sediment traps. Erosion pins and sediment traps were used at five different sites to measure hillslope surface change and trapped sediment volumes. Terrestrial laser scanning was used to model surface change where slope gradients are 1:2 or greater. Surface change was assessed in relation to slope gradient, slope length, cross-slope curvature, hillslope position and fire severity. The results suggested a threshold for substantial increased sediment yield at slope gradients of 1:2. The findings also suggested that concave cross-slope curvatures were associated with significantly larger amounts of sediment movement. Key words water reservoir; sediment trap; erosion pins; terrestrial laser scanning; slope gradient; cross-slope plan curvature, South Australia INTRODUCTION Wildfires influence soil surface processes resulting in the potential for increased sedimentation of reservoirs and impacts on water quality (Smith et al., 2011). -

Parks Victoria on behalf of the Victoria to guide future directions for Plenty Gorge Park. Victorian Government acknowledges the significance of Plenty Gorge to the Wurundjeri people and seeks The master plan conveys a long-term vision for the to reflect the views, interests and aspirations of the park and provides a framework to improve leisure Traditional Owners in using and managing the park. and recreation opportunities, whilst protecting and celebrating the park’s natural and cultural values. It identifies potential site enrichment opportunities and Report contributors locations for these based on community and stakeholder engagement and investigation of the park’s features. The project team wishes to acknowledge the input and assistance of the following: The master plan has considered directions from the previous Plenty Gorge Park Master Plan (1994) as well • Parks Victoria - Project Working Group and Project as a number of existing concept plans and precinct plans Control Group members for various areas within the park. Directions that are • Consultants who helped prepare the report: considered relevant to the current and future use of the Land Design Partnership and HM Leisure Planning park are incorporated into this document. • Authors of the many background reports on the park. As a planning document, the master plan is not intended • Wurundjeri, community and stakeholder group to provide detailed design or definition of specific uses representatives who gave their time and knowledge that industry and/or the community might ultimately during various the engagement phases.
