Short summary
We combine aerial and drone Light Detection and Ranging surveys with sediment export and density measurements to assess catchment-scale mass balance in a badland environment. Landslides and crest failures are found to contribute 15 % of total mass export while affecting only 1 % of bare surfaces. Flood-condition drainage reconstruction shows low-drainage areas export 3.5 times more sediment than other slopes.
