2014, Proceedings of the National Academy of Sciences (111) 7030-7035
By coupling synoptic data from a basin-wide assessment of streamwater chemistry with network-based geostatistical analysis, we show that spatial processes differentially affect biogeochemical condition and pattern across a headwater stream network. We analyzed a high-resolution dataset consisting of 664 water samples collected every 100 m throughout 32 tributaries in an...

Characterizing the primary material sources and dominant erosional processes for post-fire debris-flow initiation in a headwater basin using multi-temporal terrestrial laser scanning data
Dennis M. Staley, Thad A. Waslewicz, Jason W. Kean
2014, Geomorphology (214) 324-338
Wildfire dramatically alters the hydrologic response of a watershed such that even modest rainstorms can produce hazardous debris flows. Relative to shallow landslides, the primary sources of material and dominant erosional processes that contribute to post-fire debris-flow initiation are poorly constrained. Improving our understanding of how and where material is...

2014, Geophysical Research Letters (41) 2266-2274
In support of projects for monitoring geomagnetic hazards for electric power grids, we develop a simple mathematical formalism, consistent with the time causality of deterministic physics, for estimating electric fields that are induced in the Earth's lithosphere during magnetic storms. For an idealized model of the lithosphere, an infinite half‐space...

Direct measurement of sub-surface mass change using the variable-baseline gravity gradient method
Jeffrey Kennedy, Ty P.A. Ferré, Andreas Guntner, Maiko Abe, Benjamin Creutzfeldt
2014, Geophysical Research Letters (41) 2827-2834
Time-lapse gravity data provide a direct, non-destructive method to monitor mass changes at scales from cm to km. But, the effectively infinite spatial sensitivity of gravity measurements can make it difficult to isolate the signal of interest. The variable-baseline gravity gradient method, based on the difference of measurements between two...

2014, General Information Product 156
Coastal communities in Virginia are prone to flooding, particularly during hurricanes, nor’easters, and other coastal low-pressure systems. These weather systems affect public safety, personal and public property, and valuable infrastructure, such as transportation, water and sewer, and electric-supply networks. Local emergency managers, utility operators, and the public are tasked with making...
Trends in precipitation, runoff, and evapotranspiration for rivers draining to the Gulf of Maine in the United States
Thomas G. Huntington, M. Billmire
2014, Journal of Hydrometeorology (15) 726-743
Climate warming is projected to result in increases in total annual precipitation in northeastern North America. The response of runoff to increases in precipitation is likely to be more complex because increasing evapotranspiration (ET) could counteract increasing precipitation. This study was conducted to examine these competing trends in the historical...
