Performance assessments of a novel well design for reducing exposure to bedrock‐derived arsenic
Richard B. Winston, Joseph D. Ayotte
2018, Groundwater (56) 762-769
Arsenic in groundwater is a serious problem in New England, particularly for domestic well owners drawing water from bedrock aquifers. The overlying glacial aquifer generally has waters with low arsenic concentrations but is less used because of frequent loss of well water during dry periods and the vulnerability to surface‐sourced...
Tidal response of groundwater in a leaky aquifer—Application to Oklahoma
Chi-Yuen Wang, Mai-Linh Doan, Lian Xu, Andrew J. Barbour
2018, Water Resources Research (54) 8019-8033
Quantitative interpretation of the tidal response of water levels measured in wells has long been made either with a model for perfectly confined aquifers or with a model for purely unconfined aquifers. However, many aquifers may be neither totally confined nor purely unconfined at the frequencies of tidal loading but...

2018, Book chapter, Cranes and agriculture: A global guide for sharing the landscape
Cranes have a close relationship with arable and pastoral agriculture that goes back hundreds, presumably thousands of years. The landscapes and ecoregions important to cranes are also those areas most conducive to agriculture. Thus, cranes and humans are attracted to the same landscapes and will therefore have futures that remain...

Interactions and impacts of domesticated animals on cranes in agriculture
Jane E. Austin, Kunikazu Momose, George W. Archibald
2018, Book chapter, Cranes and agriculture: A global guide for sharing the landscape
Affiliations of most cranes to humans and agriculture means they often interact with a variety of domestic animals. Those interactions can be beneficial or neutral when domestic animal densities and their impact on wetland or grassland systems are low to moderate, as found in more traditional agricultural practices. The most...
