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 …

Summer 2015 at Hubbard Brook

It’s that time of year again…the Hubbard Brook Cooperator’s Meeting!  This year we celebrated the 60th anniversary of the Hubbard Brook Experimental Forest.  We had a record attendance at the meeting, and as usual, it was full of great talks and good conversations with colleagues.  Four REU students are working on hydropedology and stream network project …

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, …

New review paper on tracers in northern catchments

Abstract: We examine how tracer studies have enhanced our understanding of flow paths, residence times and sources of stream flow in northern catchments. We define northern catchments as non-glacial sites in the temperate conifer/boreal/permafrost zone, focussing our review mainly on sites in North America and Europe. Improved empirical and theoretical understanding of hydrological functioning has …
