As you watched the videos about flow generation mechanisms, one of the things that you should have noticed is that climate and landscape characteristics influence the way water gets to streams. (And the way water gets to streams influences the shape of the hydrograph.) Putting it together Below I go …
[Watershed Hydrology students: You should read the whole thing, but if you want to see the TL;DR version first, scroll way down.] The big picture Now that you’ve learned all about the four different ways to generate streamflow, you might be asking yourself why they matter. Here’s why it matters: …
Kent Wired, the electronic version of Kent State University’s student media, ran a story on Saturday about the work Kimm Jarden and I have been doing on the effectiveness of green infrastructure retrofits in a neighborhood in Parma, Ohio. Hopefully I’ll have more to say about this in the next few …
Next week, the Watershed Hydrology Lab will be well represented at the CUAHSI 2014 Biennial Colloquium. We’ll be presenting four posters, so here come the abstracts… Stormwater control measures modify event-based stream temperature dynamics in urbanized headwaters Grace Garner1, Anne Jefferson2*, Sara McMillan3, Colin Bell4 and David M. Hannah1 1School …
Next week, the Watershed Hydrology Lab will be well represented at the CUAHSI 2014 Biennial Colloquium. We’ll be presenting four posters, so here come the abstracts… Assessing impacts of green infrastructure at the watershed scale for suburban streets in Parma, Ohio Kimberly Jarden, Anne Jefferson, Jennifer Grieser, and Derek Schaefer …
I will be at the CUAHSI 3rd Biennial Colloquium on Hydrologic Science and Engineering on July 16-18, 2012 in Boulder, Colorado. I’ve been asked to speak in a session on the co-evolution of geomorphology and hydrology. This is a cool opportunity for me, as I’ve been thinking about co-evolution in …
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 Yellowstone caldera is home to thousands of geothermal springs and 75% of the world’s geysers, with kilometers-deep groundwater flow systems that tap magmatic heat sources. As that hot groundwater rises toward the surface, it interacts with shallower, cooler groundwater to produce multi-phase mixing, boiling, …
The major theme of my research is analyzing how geologic, topographic, and land use variability controls hydrologic response, climate sensitivity, and geomorphic evolution of watersheds, by partitioning water between surface and ground water. The goal of my research is to improve reach- to landscape-scale prediction of hydrologic and geomorphic response to human activities and climate change.
