Prescribed burning is routinely used as a management tool to protect assets and manage the local fire regimes. When reviewing proposed prescribed burns South Australian land managers are required to consider environmental impacts, including erosion and deposition of soil. However there is a paucity of research on how prescribed burning influences sediment movement. This research aims at comparing different possibilities to assess scales and magnitude of soil movement after fire.
Two prescribed burns in the Mount Lofty Ranges were assessed for sediment movement using visual observations, erosion pins and digital close range photogrammetry. Visual observations involved recording the fire severity and noting any erosional or depositional processes. Metal erosion pins were used to measure changes in sediment levels over time. Close range digital photogrammetry is a newly applied technique, which uses the theory of stereo-photogramme
