Bedload transport videos FTW

Today in Fluvial Processes, I’ll be talking about sediment transport. It’s one of those subjects that can easily get bogged down in lots and lots of math, but I prefer to start out with getting students to watch and describe the processes that occur as grains move along the bed …

GSA 2013: Revisiting watershed drainage density: New considerations for hydrologic prediction

While I’ll be missing the festivities at the 125th anniversary edition of the the Geological Society of America, my able collaborator Sarah Lewis will be presenting our work in a session on “Quaternary Geology and Geomorphology: Past, Present, and Future.” Here’s what she’ll be showing off: Revisiting watershed drainage density: …

AGU 2013: Transient Storage versus Hyporheic Exchange in Low-gradient Headwater Streams

Abstract season is upon us. I’ll be at AGU, where there looks to be loads of good sessions, including one on “Groundwater-Surface Water Interactions: Physical, biological, and chemical relevance“. Hopefully, my work (abstracted below) will be part of this session. Transient Storage versus Hyporheic Exchange in Low-gradient Headwater Streams A.J. …

Condit Dam Removal video

No excited Gordon like at Marmot Dam, but this is one exciting “blow and go” dam removal video. This was Condit Dam on the White Salmon River in Washington in October 2011. Spectacular to watch, and even neater knowing that there was important (and hair-raising) science being done both upstream …
