Rewati Niraula and Thomas Meixner Lead Study in Groundwater Recharge and Climate Change in the West

Monday, November 20, 2017

Groundwater recharge in the Western U.S. will change as the climate warms -- the dry southern regions will have less and the northern regions will have more, a University of Arizona-led research team reports.

"Our study asked what will be the effect of climate change on groundwater recharge in the Western U.S. in the near future, 2021-2050, and the far future, 2070-2100," said first author Rewati Niraula, now a senior research associate at the Texas Institute of Applied Environmental Research at Tarleton State University in Stephenville, Texas. The research, which used 11 different global climate models, was part of his doctoral work in the UA Department of Hydrology and Atmospheric Sciences.

The new study covers the entire U.S. West, from the High Plains states to the Pacific coast, and provides the first detailed look at how groundwater recharge may change as the climate changes, said senior author Thomas Meixner, UA professor and associate department head of hydrology and atmospheric sciences.  Read more in the original article by Mari Jensen published by UA News.org.

Jennifer McIntosh Co-PI on New $1 Million Keck Foundation Grant to Study Fluid-Rock Systems in the Paradox Basin

Wednesday, August 23, 2017

Jennifer McIntosh, Associate Professor of Hydrology and Atmospheric Sciences, is a Co-PI on a new $1 million W.M. Keck Foundation grant with UA Professor Peter Reiners (Geosciences) to study subsurface fluid-rock systems.  With the three-year grant, Reiners, McIntosh, and other team members will integrate geologic, geochemical, geochronologic and hydrogeologic observations to develop a more integrated, interdisciplinary understanding of subsurface fluid-rock systems. Prior to this, most approaches studying subsurface interactions looked only at parts of the system in isolation. Their work will focus on the Paradox Basin, located mostly in eastern Utah and western Colorado. For full details, see the original article published by UANews.org. Congratulations, Jen!

A. Richard Kassander, Jr., Noted Scientist, Educator, and Humanitarian Has Died

Founding Department Chair, Atmospheric Sciences/Institute of Atmospheric Physics, Has Died at Age 96 

Monday, August 24, 2017

Arno Richard "Dick" Kassander, Jr., UA Vice President Emeritus and Professor Emeritus, passed away on July 27, 2017 in Mesa, AZ. Dick was born in Carbondale, Pa, Sept 10,1920.  One of the most influential scientists of his generation, Kassander served as the first department head for the UA Department of Atmospheric Sciences/Institute of Atmospheric Physics and was highly instrumental in the creation of many University of Arizona units, including the Lunar and Planetary Laboratory and Flandrau Planetarium. He was also Director Emeritus of the Water Resources Research Center and, as the Graduate College Vice President for Research, collaborated with John W. Harshbarger in the formation of the UA Department of Hydrology and Water Resources. Kassander was a member of the Board of Trustees for the University Corporation for Atmospheric Research (UCAR). (Indeed, the founding UCAR meeting took place on the UA campus because of Kassander, and he served as its first chair.) An archived NCAR/UCAR OpenSky document from October 1968 (click on Staff Notes 122) shows Kassander stepping down as chair of the UCAR Board. Details of Kassander's life and many accomplishments, as well as information about a planned memorial service, are included in his obituary at Legacy.com. Our heartfelt condolences are extended to all of the Kassander family.

Arizona Board of Regents Confirms Appointment of Hoshin Gupta as Regents' Professor

Tuesday, April 18, 2017

The title of Regents’ Professor is reserved for faculty members whose exceptional achievements merit national and international distinction, and is conferred on no more than 3% of the total number of the University’s tenured and tenure track faculty members.

Hoshin Gupta, Professor in the College of Science, Department of Hydrology and Atmospheric Sciences has tackled some of the most fundamental challenges of hydrologic modeling throughout his career. His multiple path-breaking contributions have enabled researchers to improve model parameterization, hydrologic modeling, and model evaluation. His work within his field and across disciplines has contributed to enhanced understanding of human-natural system interactions. In the 1980s, Professor Gupta and his colleagues developed the first global optimization algorithm for hydrologic models. In the 1990s, Professor Gupta connected Artificial Neural Networks and hydrologic modeling, especially in the context of estimating rainfall and streamflow. This work has been foundational for efforts that retrieve global precipitation from satellite observations. In the 2000’s, Professor Gupta was Executive Director of the SAHRA science and technology center to bridge water science with decision making. More recently, he co-led development of the UA Program in Terrestrial Hydrometeorology, and led the European Union funded international transdisciplinary network to develop EU/US links through Sustainable Water ActioN (SWAN).

Professor Gupta’s work is highly recognized nationally and internationally. His extraordinary talent shines through everything he does, and his impact is broad. Professor Gupta’s excellence in the classroom, both at the graduate and undergraduate level, has been acknowledged through numerous teaching awards, and his service to the University of Arizona and to the profession is exemplary.

Associate Professor Jen McIntosh Featured in National Geographic

Monday, March 6, 2017

Dr. Jennifer McIntosh, Associate Professor of Hydrology and Atmospheric Sciences, was recently featured in a National Geographic article, "Old Water and New Knowledge at Cienega Creek."  Cienega Creek is special because it is one of the few remaining perennial streams in Southern Arizona and has been the subject of heated debate and detailed study for nearly two decades.

In the Cienega Basin in Southern Arizona, her hydrology group is using spectrographic and chemical analyses to research the "signature" of water flows, including the age of the water, and, ultimately, to expand knowledge of how the hydrology of this basin functions.  Read more at National Geographic's Water Currents website.

Regents Professor Vic Baker Featured in High Country News

Monday, February 27, 2017

Regents Professor Vic Baker's ongoing research in paleohydrology has been featured in a High Country News article, "Have we underestimated the West's superfloods? Scientists warn that enormous floods may be more likely than we thought--and the Oroville Dam and others weren't built to withstand them." 

By combing the Colorado River, the Green River, and others in the Southwest for sediment deposits and other flood evidence and then carbon-dating the results, Baker has concluded that the short-term record severely underestimates the size and frequency of large floods.
