Carrie’s manuscript on temporary stream dynamics in the Appalachians

Carrie Jensen’s first paper was accepted in Hydrological Processes this week.  Her work is about characterizing the spatial and temporal dynamics of headwater stream wetting and drying.  This manuscript documents patterns of stream network expansion, contraction, and disconnection in watersheds from New England, Appalachian Plateau, Valley and Ridge, and Blue Ridge physiographic regions.  Her research …

New paper on streamflow response to forest management and increasing precipitation extremes

Dr. Charley Kelly, a former lab member and now with the Division of Forestry and Natural Resources, West Virginia University, had a paper accepted in Geophysical Research Letters this week.  The study re-examines several paired watershed studies from the Coweeta Hydrologic Lab, but focuses on high flows, low flows, and interactions with precipitation patterns. Abstract: Increases in extreme …

New paper linking water age and solute dynamics at Hubbard Brook

Paolo Benettin’s paper was just accepted, which was the result of his study abroad visit here in the lab during the fall 2013 and spring 2014.  The manuscript explores water age-dependent transport in estimating weathering-derived solute export.   The model predicts water travel time dynamics from water stable isotope data and represents geochemical dissolution at the catchment-scale as a simple first-order kinetic …

New paper showing alternative source of stream dissolved organic carbon in a headwater catchment

JP Gannon just had another paper accepted in Water Resources Research this week.  The study suggests that dissolved organic carbon (DOC) in headwater streams may be generated from shallow to bedrock regions in the catchment, which mostly occur near the catchment divides and channel heads.  The study also suggests that hydropedological patterns are critical to understanding DOC …

Two new papers on water travel times in catchments

Two new papers are available in Water Resources Research on water travel time estimation in catchments.  Both represent collaborations with colleagues to advance techniques in understanding the transient nature of travel time distributions.  We’re getting closer and closer to answering the question: how old is that water in the stream? Rinaldo, A., Benettin, P., Harman, …

New paper on lidar DEM evaluation by Cody Gillin

Gillin, C.P., Bailey, S.W., McGuire, K.J., Prisley, S.P., 2015. Evaluation of lidar-derived DEMs through terrain analysis and field comparison, Photogrammetric Engineering & Remote Sensing, 81(5): 387-396, doi: 10.14358/PERS.81.5.387. Abstract Topographic analysis of watershed-scale soil and hydrological processes using digital elevation models (DEMs) is commonplace, but most studies have used DEMs of 10 m resolution or coarser. …

New paper published on erosion modeling on forest roads

Kris Brown had another paper published.  The study evaluated the model Water Erosion Prediction Project (WEPP) in predicting event-based sediment yield and runoff for a series of rainfall experiments on six stream-crossing sections of forest roads with different intensities of best management practices.  For more information, please check out the paper. Brown, K.R., McGuire, K.J., Hession, W.C., and Aust, …

Paper published on mapping of hydropedologic spatial patterns

A paper from Cody Gillin’s master’s thesis was accepted last week.  The manuscript titled “Mapping of hydropedologic spatial patterns in a steep headwater catchment” will be published in a special issue on hydropedology in the Soil Science Society of America Journal.  This paper appears in the special issue with another paper on the same project, …

New paper about how forests lose nitrogen through shallow groundwater flowpaths

In a paper published in the Proceedings of the National Academy of Sciences, McGuire working with a team from the Hubbard Brook Ecosystem Study found clear evidence of nitrogen loss through denitrification in isolated shallow groundwater patches in a small watershed. The findings were somewhat of a surprise because denitrification has been so difficult to …
