BadlandScan: dynamic patterns of erosion and deposition in badlands from high resolution surveys

PI: Mark Smith

Overview: Badlands demonstrate high erosion rates which make disproportionate contributions to catchment sediment budgets. Small-scale erosion-plot studies are common while remote sensing methods yield extensive yet coarser topographic surveys. Advances in surveying technology have renewed impetus towards filling the resultant scale gap, balancing competing demands of spatial resolution and survey extent by offering more extensive and distributed representation of erosional processes than erosion pins, profile meters, or sediment collections at greater resolution than airborne LiDAR.

The aim of this project is to evaluate controls of erosion and sediment transfer in badlands using multi-temporal high-resolution topographic models at both sub-catchment and system scales acquired using terrestrial laser scanning (TLS) and 'Structure from Motion' (SfM).
