These four papers all attempt to understand what controls the sediments that make up the streambed and floodplain and that get preserved in the geologic record. White et al. look at how riffle positions are governed by valley width variations, while Jerolmack and Brzinski find striking similarities in grain size transitions observed in rivers and dune fields. Hart et al. examine the relationship between glacial advances and downstream sediment deposition, while Sambrook Smith et al. investigate the sedimentological record of floods. Continue reading
How do rivers erode bedrock streams, during big floods, and in the presence of groundwater? Laboratory and accidental experiments are providing some cool new insights. Continue reading

I see ways that we can expand what we are doing, to make our community bolder, more inclusive, and more outwardly focused. Building that sort of community allows us not just to provide camaraderie and support for one another, but also to act as agents of change beyond the borders of the internet. Continue reading →
