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 …

New paper by Gannon on organizing groundwater regimes and response thresholds by soils

JP Gannon had a paper accepted this week in Water Resources Research titled “Organizing groundwater regimes and response thresholds by soils: A framework for understanding runoff generation in a headwater catchment.” Here’s the abstract: A network of shallow groundwater wells in a headwater catchment at the Hubbard Brook Experimental Forest in New Hampshire, USA was …

Congratulations Kris!

Kris Brown successfully defended his dissertation yesterday. Congratulations to Kris. The title of his dissertation was “Sediment delivery from reopened forest roads at stream crossings in the Virginia Piedmont physiographic region, USA”  

Forest road gravel cover and reduced sediment delivery to stream crossings paper accepted

Kris Brown’s paper on “the effect of increasing gravel cover on forest roads for reduced sediment delivery to stream crossings” was accepted this week in Hydrological Processes. Abstract Direct sediment inputs from forest roads at stream crossings are a major concern for water quality and aquatic habitat. Legacy road-stream crossing approaches, or the section of …

News release – Ecology team improves understanding of valley-wide stream chemistry

BLACKSBURG, Va., April 22, 2014 – A geostatistical approach for studying environmental conditions in stream networks and landscapes has been successfully applied at a valley-wide scale to assess headwater stream chemistry at high resolution, revealing unexpected patterns in natural chemical components. “Headwater streams make up the majority of stream and river length in watersheds, affecting regional …

Network chemistry patterns in headwater streams – new paper published in PNAS

In a new article published this week in Proceedings of the National Academy of Sciences, we show how high-resolution mapping and analysis of water chemistry throughout a headwater stream network reveals unexpected patterns in how flowing water interacts with the surrounding landscape at multiple spatial scales.  Here’s the abstract and a link to the paper: …

New paper on the hydropedology of Hubbard Brook

A new paper was accepted this week in the journal Geoderma.  The paper shows how spatial patterns of soil development reflect the influence of transient groundwater within the soil profile in nearly all landscape positions throughout a headwater catchment at the Hubbard Brook Experimental Forest.  This study was initiated by Patricia Brousseau’s REU project in 2008. …

Where does the water go?

Hydrology isn’t always fun and games, but in this case it is. The watershed hydrology lab at Virginia Tech and the WC (Virginia Water Resources Research Center) bring you “Where does the water go?”. We wrote and rehearsed this song roughly 2 hours before performing, so hang in there on some of the missteps and …
