Anne's picks of the June literature: Humans as Agents of Hydrologic Change
How large reservoirs affect our measurements of global sea level rise…and how the world’s biggest river basins are going to respond to mid-century climate change

Braided river meets mountain gorge: The Snake River escapes Jackson Hole
Though I don’t think anything can top Kyle’s pathologically misdirected RYNHO, I recently had cause to contemplate a river that everyone has heard of – the Snake River of the northwestern United States. Now, the Snake River has a famous gorge, a famous lava plain, and it’s had a famously …
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
When it rains a lot and the mountains fall down
Cross-posted at Highly Allochthonous The geo-image bonanza of this month’s Accretionary Wedge gives me a good reason to make good on a promise I made a few months ago. I promised to write about what can happen on the flanks of Pacific Northwest volcanoes when a warm, heavy rainfall hits …
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 …
My picks of the November literature
It is not that there was no October literature to pick. My time to read articles simply disappeared in the lead-up to and excitement of the Geological Society of America meeting. This month, however, I am back on track and I will try to update this post as I move …
How to build a meandering river in your basement
This post is cross-posted at Highly Allochthonous. Please look over there for 15+ comments on the post. Meandering rivers are characterized by regularly spaced bends that grow and cutoff and generally march downstream in a fairly orderly fashion. Click the image below to watch a movie of meander migration on …
Megafloods from Glacial Lake Missoula
[Cross-posted at Highly Allochthonous] If I had a time machine and could go back to any point in geologic history, as supposed in this month’s Accretionary Wedge call, the event I’d most like to see is the repeated flooding of the Pacific Northwest at the end of the last Ice …
