NabhanPreliminary geohydrologic assessment of Buenos Aires National Wildlife Refuge, Altar Valley, southeastern Arizona
The Buenos Aires National Wildlife Refuge is located in the southern part of Altar Valley, southwest of Tucson in southeastern Arizona. The primary water-supply well at the Buenos Aires National Wildlife Refuge has experienced a two-decade decrease in groundwater levels in the well, as have other wells in the southern part of Altar Valley. In part to understand this trend, a study was undertaken bAuthorsSandra J. Owen-Joyce, James B.

The Sky Island Restoration Collaborative (SIRC) is a growing partnership between government agencies, nonprofit organizations, and private landowners in southeast Arizona, the United States, and northern Sonora, Mexico. Starting in 2014 as an experiment to cultivate restoration efforts by connecting people across vocations and nations, SIRC has evolved over 5 years into a flourishing landscape-resAuthorsLaura M.

Valer Austin-ClarkPreliminary assessment of carbon and nitrogen sequestration potential of wildfire-derived sediments stored by erosion control structures in forest ecosystems, southwest USA
The role of pyrogenic carbon (PyC) in the global carbon cycle is still incompletely characterized. Much work has been done to characterize PyC on landforms and in soils where it originates or in “terminal” reservoirs such as marine sediments. Less is known about intermediate reservoirs such as streams and rivers, and few studies have characterized hillslope and in-stream erosion control structuresAuthorsJames B. Callegary, Laura M. Norman, Christopher J. Eastoe, Joel B. Sankey, Ann YoubergModeling riparian restoration impacts on the hydrologic cycle at the Babacomari Ranch, SE Arizona, USA
This paper describes coupling field experiments with surface and groundwater modeling to investigate rangelands of SE Arizona, USA using erosion-control structures to augment shallow and deep aquifer recharge. We collected field data to describe the physical and hydrological properties before and after gabions (caged riprap) were installed in an ephemeral channel.

Study RegionThis study region encompasses the Transboundary San Pedro and Santa Cruz aquifers which are shared between the states of Sonora (Mexico) and Arizona (US). Special regional considerations include a semi-arid climate, basin-fill aquifers with predominantly montane recharge areas, economic drivers in the mining, trade, and military sectors, groundwater-dependent cities with expanding coneAuthorsJames B.

Geophysical methods were used to monitor infiltration during a water release, referred to as a “pulse flow,” in the Colorado River delta in March and April 2014. The pulse flow was enabled by Minute 319 of the 1944 United States–Mexico Treaty concerning water of the Colorado River.

This study assessed progress toward achieving sustainable groundwater use in the Sierra Vista Subwatershed of the Upper San Pedro Basin, Arizona, through evaluation of 14 indicators of sustainable use. Sustainable use of groundwater in the Sierra Vista Subwatershed requires, at a minimum, a stable rate of groundwater discharge to, and thus base flow in, the San Pedro River. Many of the 14 indicatoAuthorsBruce Gungle, James B. Callegary, Nicholas V. Paretti, Jeffrey R. Kennedy, Christopher J. Eastoe, Dale S. Turner, Jesse E. Dickinson, Lainie R. Levick, Zachary P.

The United States and Mexico share waters in a number of hydrological basins and aquifers that cross the international boundary. Both countries recognize that, in a region of scarce water resources and expanding populations, a greater scientific understanding of these aquifer systems would be beneficial. In light of this, the Mexican and U.S. Principal Engineers of the International Boundary and WAuthorsJames B.

In this study, hydrological processes are evaluated to determine impacts of stream restoration in the West Turkey Creek, Chiricahua Mountains, southeast Arizona, during a summer-monsoon season (June–October of 2013). A paired-watershed approach was used to analyze the effectiveness of check dams to mitigate high flows and impact long-term maintenance of hydrologic function. One watershed had beenAuthorsLaura M.

Groundwater in the US state of Alaska is critical to both humans and ecosystems. Interactions among physiography, ecology, geology, and current and past climate have largely determined the location and properties of aquifers as well as the timing and magnitude of fluxes to, from, and within the groundwater system. The climate ranges from maritime in the southern portion of the state to continentalAuthorsJ.B. Callegary, C.P. Kikuchi, Joshua C. Koch, M. R. Lilly, S. A.

Along the United States–Mexican border, the health of communities, economies, and ecosystems is inextricably intertwined with the availability and quality of water, but effective water management in the Borderlands is complicated. Water users compete for resources, and their needs are increasing.

Transboundary Aquifer Assessment Program (TAAP)
Many communities along the U.S.-Mexico border have limited surface water supply and rely on transboundary aquifers for industry, agriculture, and drinking water; however, information on water needs, water quality, and the extent and functioning of these aquifers is incomplete. The Transboundary Aquifer Assessment Program (TAAP), established through a binational agreement between the United States...Assessing the Impacts of Restoration Efforts on Water and Natural Systems in a Changing World
Resource managers must balance the impacts of competing management decisions on multiple, interacting natural systems. Hydrologic and ecological processes, such as groundwater fluctuations and riparian evapotranspiration, can be tightly coupled. Ideally, managers would have tools and models that include all processes to better understand how each management action would propagate through the envir
