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 …
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 …
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
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 …
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 …
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 …
About two months ago, I noted with great sadness the passing of a legendary figure in fluvial geomorphology, M. Gordon “Reds” Wolman, long-time professor at The Johns Hopkins University and inspiration to hundreds, if not thousands, of geomorphologists, hydrologists, and environmental scientists around the world. In the past two months, …
The Chippewa River drains the glaciated terrains of north-central Wisconsin including major outwash plains from the margins of the Laurentide Ice Sheet. The sand carried by the Chippewa is a major sediment source for the Upper Mississippi River for tens of miles downstream. The Chippewa forms a beautiful delta into …
I spent a summer in college staring at maps and aerial photographs of the Rio Grande delta in Texas and Mexico. Maybe now I can get some use out of it. I was working with J.D. Stanley at the Smithsonian’s NMNH and he pointed me to the apparently high sinuosity …
Hunting for a Where on Google Earth location a while ago I ran across this wonderful tidally-influenced delta on the northwest coast of Madagascar. It is the mouth of the Betsiboka River and just north of the river mouth is the second largest port in Madagascar. What struck me about …
