Anne's picks of the literature: river and floodplain sediments

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.

New publication: Coevolution of hydrology and topography on a basalt landscape in the Oregon Cascade Range, USA

How does a landscape go from looking like this… to looking like this? Find out in my new paper in Earth Surface Processes and Landforms. Hint: Using a chronosequence of watersheds in the Oregon Cascades, we argue that the rates and processes of landscape evolution are driven by whether the …

FYI: NCED Summer Institute on Earth-surface Dynamics

I basically recommend anything this NCED group puts together. The short courses on Mountain Rivers and Sand-bed Rivers that I took as late-stage PhD student were absolutely fantastic. HOW DOES VEGETATION INFLUENCE LARGE-SCALE TOPOGRAPHIC FORM? —————————————————————————————————————————– In order to adequately describe the interactions among the physical, biological, geochemical, and anthropogenic …

Delta upon Delta

For some reason the last few days have seen me browsing the semi-frozen areas of the Earth and in my search for the perfect thermokarst landscape, I’ve run across some really nice deltas. I don’t know anything about the one below other than its location in far northwestern Saskatchewan, but …
