Watershed Hydrology Trip to Susquehanna Shale Hills Critical Zone Observatory

Kent State University Department of Geology’s Watershed Hydrology class visited the Susquehanna Shale Hills Critical Zone Observatory on April 5-6, 2014. Penn State post-doc Pamela Sullivan gave them a tour of the watershed and its instrumentation, with a focus on how the measurements could contribute to understanding how hydrology drives …

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. …

Mackenzie Osypian defends her thesis on stream restoration and transient storage

Mackenzie Osypian is defending her MS research in Civil Engineering at UNC Charlotte, April 22nd at 4:00 pm in McEniry Hall 441 on the UNC Charlotte campus. Mackenzie is advised by Anne Jefferson and Sandra Clinton. John Daniels and Jim Bowen are on her committee. Mackenzie’s research is titled: “Evaluating …

New paper in press: Jefferson and McGee, Channel network extent …in the North Carolina Piedmont

Jefferson, A. and McGee, R.W. in press. Channel network extent in the context of historical land use, flow generation processes, and landscape evolution in the North Carolina Piedmont, Earth Surface Processes and Landforms Here’s the abstract: Intensive agricultural land use in the 18th through early 20th centuries on the southeastern …

Abstract: Timescales of drainage network evolution are driven by coupled changes in landscape properties and hydrologic response

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 …

AGU 2011 abstract: Understanding channel network extent in the North Carolina Piedmont in the context of legacy land use, flow generation processes, and landscape dissection

The following talk will be presented by Anne at the 2011 AGU fall meeting on Wednesday, December 7th from 9 to 9:15 am in the session “EP31G. Predictive Understanding of Coupled Interactions Among Water, Life, and Landforms II.” It will be in rooms 2022-2024, and the abstract acceptance said something …

GSA 2011 abstract: Spatial variability in groundwater-stream interactions in first-order North Carolina Piedmont streams

At the 2011 GSA Meeting in Minneapolis next week, I’ll be presenting the following talk in the session “Monitoring and Understanding Our Landscape for the Long Term through Small Catchment Studies I: A Tribute to the Career of Owen P. Bricker.” My talk is in Minneapolis Convention Center: Room M100FG, …

When a tree falls in a stream, there's always something around to make use of it.

Cross-posted at Highly Allochthonous (for obvious reasons) Allochthonous may have some obscure usage related to rocks, but in ecology, allochthonous material is a major concept that underpins thinking about nutrient cycling and food web dynamics. In its most general definition, allochthonous material is something imported into an ecosystem from outside …
