WRRC Brown Bag Seminars Focus on Atmospheric Rivers and Binational Aquifers
On February 12, the WRRC hosted Marty Ralph, Director, Center for Western Weather and Water Extremes and Researcher at UC San Diego's Scripps Institution of Oceanography to discuss Atmospheric River Science. Rivers of water vapor in the sky, which is how Dr. Ralph describes atmospheric rivers, are key to understanding the character of storm fronts and precipitation in the western United States. Forming at relatively low altitudes, and holding unusually large water loads as they move eastward over the Pacific Ocean, atmospheric rivers can be linked to extreme rainfall, causing flooding and providing water supply, when they make landfall. Ralph described the methods for studying these systems and provided data showing the importance of atmospheric rivers, when evaluating storm patterns in the desert southwest.
Mandla Kunnie has created a digital database of the locations of all rainwater harvesting infrastructure in the Tucson area. Such a database can help water managers plan for population growth and the associated increased demand on water resources.
World Water Day is a good day for reflection. Just a few days ago, on March 19, 2019, representatives of the seven states of the Colorado River Basin gathered in Phoenix, Arizona to sign a letter asking Congress to approve implementation of the drought contingency plans detailed in the documents attached to the letter.
Water management is among the most pressing issues in Arizona and throughout the Southwest.
We are pleased to announce the winners of the 2018 Water Resources Research Center Photo Contest. This year we again gave photographers two criteria - that photos be water related and that they be taken in Arizona. And we received many wonderful submissions. People, nature, Arizona and other topics were showcased by the many photographers who submitted their images.
This February, the WRRC annual conference, "Arizona Runs on Water: Scarcity, Challenges, and Community-based Solutions", will be held in our state's capital and will feature case-studies about water from across Arizona.
