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

Brian McGlynn visited us last week

  Brian McGlynn from Duke University visited the lab last week.  Brian gave a great seminar that was co-hosted by ICTAS and the Water Center.  It was well attended and generated great discussion.  We all thank Brian for coming to visit

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
