EGU Abstract: Potential impact of lava flows on regional water supplies: case study of central Oregon Cascades volcanism and the Willamette Valley, USA

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 …

AGU 2011 abstract: Controls on the hydrologic evolution of Quaternary volcanic landscapes

The following talk will be presented in the 2011 AGU fall meeting session on “EP41F. Posteruptive Processes Operating on Volcanic Landscapes I” on Thursday, December 8th from 9:15 to 9:30 am. Controls on the hydrologic evolution of Quaternary volcanic landscapes Anne J. Jefferson and Noemi d’Ozouville 1. Geography and Earth …

New paper: Seasonal versus transient snow and the elevation dependence of climate sensitivity in maritime mountainous regions

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 …

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 …

GSA Abstract: On a template set by basalt flows, hydrology and erosional topography coevolve in the Oregon Cascade Range

The Watershed Hydrogeology Lab is going to be busy at this year’s Geological Society of America annual meeting in Portland, Oregon in October. We’ve submitted four abstracts for the meeting, I am co-convening a session, and I’ll be helping lead a pre-meeting field trip. I’ll be an invited speaker in …

Cascades hydrogeology on front page of the Oregonian

The front page feature of today’s Oregonian (Portland’s major newspaper) features research on groundwater in the Cascades: The secret’s out: Tons of water in Oregon’s Cascades. Scientists from the U.S. Forest Service and Oregon State University have in recent years quietly realized that the high Cascades in Oregon and far …
