Short summary
We document the responses of bedrock-confined rivers to an extreme flood which occurred in southeast Queensland, Australia, in 2011. Through a combination of field- and desktop-based analyses we show that widespread removal of coarse-grained mantle occurred, with boulders up to 4m in diameter being locally mobilised. We show that normalised erosion in this extreme event is scaled to basin area and that this large flood has exposed bedrock steps and straths exposing them to ongoing erosion.
We document the responses of bedrock-confined rivers to an extreme flood which occurred in...
