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

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

Contribution to new textbook on the critical zone

A new textbook called Principles and Dynamics of the Critical Zone was just published.  I co-authored a chapter of the book on Ecohydrology in the Critical Zone with Georgianne Moore, Peter Troch and Greg Barron-Gafford.  Here is the publisher’s description of the

Sprinkling on the model

Kevin, Brian, and I went to Coweeta to improve the irrigation system. They installed a pressure pump to the water line, then we placed tipping bucket rain gauges at randomized locations, and then Brian turned on the water. Water pressure

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

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

Filtration, Irrigation, and Preliminary Instrumentation

Kevin, Brian, and I installed a reverse osmosis filtration system, an irrigation line, an electrical line, and several data instruments/loggers. This included pounding a 7-foot copper grounding rod into the ground. The filtration system is used to change the chemistry

Hoop-House at Coweeta

Construction on the soil model at Coweeta Hydrologic Laboratory has begun! We will be using the model for a water and nutrient reaction and transport experiment to answer questions, such as: What is the dominant process (e.g., biogeochemical or hydrologic) for

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
