Application and evaluation of electromagnetic methods for imaging saltwater intrusion in coastal aquifers: Seaside Groundwater Basin, California
Vanessa Nenna, Daan Herckenrather, Rosemary Knight, Nick Odlum, Darcy McPhee
2013, Geophysics (78) B77-B88
Developing effective resource management strategies to limit or prevent saltwater intrusion as a result of increasing demands on coastal groundwater resources requires reliable information about the geologic structure and hydrologic state of an aquifer system. A common strategy for acquiring such information is to drill sentinel wells near the coast...

2013, Journal of Hydrology (481) 22-34
Currently, little is known about the impact of climate change on groundwater recharge in the Sierra Nevada and southern Cascade Range of California or other mountainous regions of the world. The purpose of this study was to determine whether small alpine peat lands called fens can be used as whole-ecosystem...
Nitrate in watersheds: straight from soils to streams?
Elizabeth B. Sudduth, Steven S. Perakis, Emily S. Bernhardt
2013, Journal of Geophysical Research G: Biogeosciences (118) 291-302
Human activities are rapidly increasing the global supply of reactive N and substantially altering the structure and hydrologic connectivity of managed ecosystems. There is long-standing recognition that N must be removed along hydrologic flowpaths from uplands to streams, yet it has proven difficult to assess the generality of this removal...

Celeste A. Journey, Karen M. Beaulieu, Paul M. Bradley
2013, Book chapter, Current perspectives in contaminant hydrology and water resources sustainability
Phytoplankton are small to microscopic, free-floating algae that inhabit the open water of freshwater, estuarine, and saltwater systems. In freshwater lake and reservoirs systems, which are the focus of this chapter, phytoplankton communities commonly consist of assemblages of the major taxonomic groups, including green algae, diatoms, dinoflagellates, and cyanobacteria. Cyanobacteria...
Crowdsourcing to Acquire Hydrologic Data and Engage Citizen Scientists: CrowdHydrology
Michael N. Fienen, Chris Lowry
2013, Ground Water (51) 151-156
Spatially and temporally distributed measurements of processes, such as baseflow at the watershed scale, come at substantial equipment and personnel cost. Research presented here focuses on building a crowdsourced database of inexpensive distributed stream stage measurements. Signs on staff gauges encourage citizen scientists to voluntarily send hydrologic measurements (e.g., stream...

Wetland dynamics influence mid-continent duck recruitment
Michael J. Anteau, Aaron T. Pearse, Michael L. Szymankski
2013, Conference Paper, Proceedings of North American Duck Symposium and Workshop
Recruitment is a key factor influencing duck population dynamics. Understanding what regulates recruitment of ducks is a prerequisite to informed habitat and harvest management. Quantity of May ponds (MP) has been linked to recruitment and population size (Kaminski and Gluesing 1987, Raveling and Heitmeyer 1989). However, wetland productivity (quality) is...

Hydrogeomorphology influences soil nitrogen and phosphorus mineralization in floodplain wetlands
Gregory B. Noe, Cliff R. Hupp, Nancy B. Rybicki
2013, Ecosystems (16) 75-94
Conceptual models of river–floodplain systems and biogeochemical theory predict that floodplain soil nitrogen (N) and phosphorus (P) mineralization should increase with hydrologic connectivity to the river and thus increase with distance downstream (longitudinal dimension) and in lower geomorphic units within the floodplain (lateral dimension). We measured rates of in situ...
Prediction, time variance, and classification of hydraulic response to recharge in two karst aquifers
Andrew J. Long, Barbara Mahler
2013, Hydrology and Earth System Sciences (17) 281-294
Many karst aquifers are rapidly filled and depleted and therefore are likely to be susceptible to changes in short-term climate variability. Here we explore methods that could be applied to model site-specific hydraulic responses, with the intent of simulating these responses to different climate scenarios from high-resolution climate models. We...
