Water monitoring review for the Kangaroo Island Natural Resource Management Region, DWLBC Report 2006/16, Government of South Australia, through Department of Water, Land and Biodiversity Conservation, Adelaide. FOREWORD South Australia’s unique and precious natural resources are fundamental to the economic and social wellbeing of the State. It is critical that these resources are managed in a sustainable manner to safeguard them both for current users and for future generations. The Department of Water, Land and Biodiversity Conservation (DWLBC) strives to ensure that our natural resources are managed so that they are available for all users, including the environment. In order for us to best manage these natural resources it is imperative that we have a sound knowledge of their condition and how they are likely to respond to management changes. DWLBC scientific and technical staff continues to improve this knowledge through undertaking investigations, technical reviews and resource modelling.

    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).
