UCI water and drought expert Amir AghaKouchak gets work published in three major journals within two weeks Brian Bell / UCI Here in drought-stricken California, lots of families have dinnertime discussions about water, but rarely do they have the same depth and insight as those happening in the AghaKouchak household. Amir AghaKouchak, assistant professor of civil & environmental engineering at the University of California, Irvine, is an expert on drought and water issues; and his wife,...

A third of the world’s biggest groundwater basins are in distress

Written on June 16, 2015.

Irvine, Calif., June 16, 2015 – Two new studies led by UC Irvine using data from NASA Gravity Recovery and Climate Experiment satellites show that human consumption is rapidly draining some of its largest groundwater basins, yet there is little to no accurate data about how much water remains in them. The result is that significant segments of Earth’s population are consuming groundwater quickly without knowing when it might run out, the researchers conclude. The findings appear today in Water...

California’s Water House of Cards

Written on September 23, 2013.

Groundwater supplies at least a third of the state’s water. But it’s being depleted at a rapid pace, despite efforts to recharge it. Jay Famiglietti and Sasha Richey, Los Angeles Times Gov. Jerry Brown’s Office of Planning and Research convened a meeting this month of groundwater experts from the University of California to determine what is currently known about the state’s underground water reserves and how they may be changing in the future. This and other recent...

Water in the Balance

James S. Famiglietti, Matthew RodellScience Magazine Earth’s climate is changing, and so is its hydrologic cycle. Recent decades have witnessed rising rates of global precipitation, evaporation, and freshwater discharge (1). Extreme flooding is occurring with greater intensity and frequency in some regions; in others, extreme drought is becoming more common (2). Most climate models indicate that by the end of this century, the dry regions of the world will become drier, whereas the wet...

Satellite data explains vanishing India groundwater

Written on August 12, 2009.

Using satellite data, UC Irvine and NASA hydrologists have found that groundwater beneath northern India has been receding by as much as 1 foot per year over the past decade – and they believe human consumption is almost entirely to blame. Jennifer Fitzenberger, University Communications, and NASA Earth Science News Team Using satellite data, UC Irvine and NASA hydrologists have found that groundwater beneath northern India has been receding by as much as 1 foot per year over the...
