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 …

Urban streams with green walls

For large urban streams, the standard practices in stream and habitat restoration are sometimes not possible, often because decades of infrastructure development have pinned the stream into a narrow corridor. So other approaches need to be considered, and Robert Francis and Simon Hoggart of King’s College London discuss ways that existing artificial structures can be put to work to mitigate some of the ecological impacts of urbanization

Conference presentation: Effects of river management & sediment supply on island evolution in Pool 6 of the Upper Mississippi River, southeast Minnesota

Watershed Hydrogeology Lab graduate student Brock Freyer has spent the last two years learning deeply about the hydrology, geomorphology, and sedimentology of the Upper Mississippi River System, as well as learning to use some sophisticated GIS techniques for 3-D analysis of topographic data. This week he is presenting the results …

My picks of the December literature

Cross-posted at Highly Allochthonous I’m a few days behind on sharing my picks from December’s journals, but Chris has been doing such a stupendous job of sharing absolutely wonderful geology posts (and of deconstructing terrible science reporting), that I hardly feel guilty waiting until he’s occupied with travels before sneaking …
