Flow reconstructions in the Upper Missouri River Basin using riparian tree rings
Derek M. Schook, Jonathan M. Friedman, Sara L. Rathburn
2016, Water Resources Research (52) 8159-8173
River flow reconstructions are typically developed using tree rings from montane conifers that cannot reflect flow regulation or hydrologic inputs from the lower portions of a watershed. Incorporating lowland riparian trees may improve the accuracy of flow reconstructions when these trees are physically linked to the alluvial water table. We...

2016, Annual Review of Environment and Resources (41) 399-423
Transformative governance is an approach to environmental governance that has the capacity to respond to, manage, and trigger regime shifts in coupled social-ecological systems (SESs) at multiple scales. The goal of transformative governance is to actively shift degraded SESs to alternative, more desirable, or more functional regimes by altering the...
Fragmented patterns of flood change across the United States
Stacey A. Archfield, Robert M. Hirsch, A. Viglione, G. Blöschl
2016, Geophysical Research Letters (43) 10232-10239
Trends in the peak magnitude, frequency, duration, and volume of frequent floods (floods occurring at an average of two events per year relative to a base period) across the United States show large changes; however, few trends are found to be statistically significant. The multidimensional behavior of flood change across...
Linking field-based metabolomics and chemical analyses to prioritize contaminants of emerging concern in the Great Lakes basin
John M. Davis, Drew R. Ekman, Quincy Teng, Gerald T. Ankley, Jason P. Berninger, Jenna E. Cavallin, Kathleen M. Jensen, Michael D. Kahl, Anthony L. Schroeder, Daniel L. Villeneuve, Zachary G. Jorgenson, Kathy Lee, Timothy W. Collette
2016, Environmental Toxicology and Chemistry (35) 2493-2502
The ability to focus on the most biologically relevant contaminants affecting aquatic ecosystems can be challenging because toxicity-assessment programs have not kept pace with the growing number of contaminants requiring testing. Because it has proven effective at assessing the biological impacts of potentially toxic contaminants, profiling of endogenous metabolites (metabolomics)...

Regional land subsidence caused by the compaction of susceptible aquifer systems accompanying groundwater extraction
Devin L. Galloway, Stanley A. Leake
Vijay P. Singh, editor(s)
2016, Book chapter, Handbook of applied hydrology
Land subsidence includes both gentle downwarping and sudden sinking of segments of the land surface. Major anthropogenic causes of land subsidence are extraction of fluids including water, oil, and gas. Measurement and detec- tion of land subsidence include both ground-based and remotely sensed air- borne and space-based methods. Methods for measurement of subsidence at points...

Assessing potential scour using the South Carolina bridge-scour envelope curves
Stephen T. Benedict, Toby D. Feaster, Andral W. Caldwell
2016, Fact Sheet 2016-3065
SummaryBridge-scour equations presented in the Federal Highway Administration Hydraulic Engineering Circular No. 18 reflect the current state-of-the practice for predicting scour at bridges. Although these laboratory-derived equations provide an important resource for assessing scour potential, there is a measure of uncertainty when applying these equations to field conditions. The uncertainty...
