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 …
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: …
Network chemistry patterns in headwater streams – new paper published in PNAS Read More »
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. …
Kris Brown had his first journal article accepted this week in Forest Ecology and Management. Congrats Kris!! Abstract: Forest road stream crossing approaches, or the section of road immediately adjacent to the stream crossing, represent primary sources and nearly direct pathways for sediment delivery to stream channels. This research quantified sediment delivery rates associated with reopening …
Sectoral contributions to surface water stress in the coterminous United States K Averyt et al. 2013 Environ. Res. Lett. 8 035046 This article seems to be receiving a fair bit of hype. Sandra Postel blogs about the paper on National Geographic’s Freshwater Initiative and the American Water Resources Association has posted about it as well. …
A special issue of the journal Hydrological Processes called “Catchments in the future North: interdisciplinary science for sustainable management in the 21st Century” reports on the results from our North-Watch project. This is a great collection of papers on the future of northern watershed hydrology and how these systems respond to changing climate. Dr. McGuire is …

A paper from our North-Watch project was accepted and published online today. The findings suggest that one likely consequence of warmer winters in northern regions is that the proportion of the annual DOC and water export will increase during winter and decrease during spring and summer. Laudon, H., D. Tetzlaff, C. Soulsby, S. Carey, …

We had a couple of new papers come out this week. One is from our North-Watch project, which is a collaborative project aimed at predicting the integrated consequences of climate change on the physical, chemical and biological characteristics of water resources in experimental watersheds in sensitive northern climates. The other paper is from an education project …
Some of the largest rainfall accumulations in the world have observed have been in the central Appalachian region. A new paper that came out this week in Water Resources Research characterizes features that lead to these large orographic/convective storms that occur predominantly during the summer. Complex interactions between topography and storm dynamics are not well …
