Legendary fluvial geomorphologist Reds Wolman once said “Floods come from too much water,” and that’s the phenomenon distilled to its core essence. But this bit of wisdom doesn’t give us much to go on if we want to understand what creates floods or why some areas are more flood-prone than …
If you haven’t seen it yet, and you are at all interested in dams and dam removal (or are even wondering why people would be interested in dam removal), I encourage you to watch the film Damnation. The film highlights some of the environmental issues associated with dams, showcases the …
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 …
My favorite way to get students excited about dam removal is this video produced by Oregon Public Broadcasting, on the removal of Marmot Dam, near Portland, Oregon in 2008. Part of the reason I love this video is it shows off Gordon Grant‘s enthusiasm for river science.
This abstract was just submitted to the European Geosciences Union meeting for a session on “NH9.9. Natural hazard impact on technological systems and urban areas.” I won’t get to go to Vienna in April, but at least a little bit of my science will. Thanks to Natalia for finding a …
Jefferson, A. 2011. Seasonal versus transient snow and the elevation dependence of climate sensitivity in maritime mountainous regions, Geophysical Research Letters, 38, L16402, doi:10.1029/2011GL048346. Abstract: In maritime mountainous regions, the phase of winter precipitation is elevation dependent, and in watersheds receiving both rain and snow, hydrologic impacts of climate change …
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 …
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 …
Described below is a great post-doc opportunity to work with fantastic people. (I should know, I did my PhD and post-doc in this research group.) We are looking for someone to co-lead a multi-year, inter-institutional research effort to characterize and forecast the effects of changing climate on streamflows and geomorphic …
For undergraduates thinking about graduate school, here’s a program that incorporates the classes and research of an MS program with the opportunity to work in K-12 classrooms and building your teaching and outreach skills and credentials. I know some of the faculty at Central Washington, and they would be great …
