35-year Mega-Drought coming for San Joaquin Valley and the American Southwest?

Wed, 09/03/2014 - 20:22

   A new study by Cornell University, the University of Arizona, and the US Geological Survey researchers looked at the deep historical record (tree rings, etc.) and the latest climate change models to estimate the likelihood of major droughts in the Southwest over the next century. The results are as soothing as a thick wool sweater on a midsummer desert hike, according to Mother Jones Magazine.

   The researchers concluded that odds of a decadelong drought are "at least 80 percent." The chances of a "megadrought" one lasting 35 or more years, stands at somewhere between 20 percent and 50 percent, depending on how severe climate change turns out to be. And the prospects for an "unprecedented 50-year megadrought" — one "worse than anything seen during the last 2000 years" — checks in at a nontrivial 5 to 10 percent.

The Power of Salt

Wed, 08/20/2014 - 09:54
CAMBRIDGE, Mass. -- Where the river meets the sea, there is the potential to harness a significant amount of renewable energy, according to a team of mechanical engineers at Massachusetts Institute of Technology (MIT). The researchers evaluated an emerging method of power generation called pressure retarded osmosis (PRO), in which two streams of different salinity are mixed to produce energy. In principle, a PRO system would take in river water and seawater on either side of a semi-permeable membrane. Through osmosis, water from the less-salty stream would cross the membrane to a pre-pressurized saltier side, creating a flow that can be sent through a turbine to recover power. The MIT team has now developed a model to evaluate the performance and optimal dimensions of large PRO systems. In general, the researchers found that the larger a system’s membrane, the more power can be produced — but only up toa point. Interestingly, 95 percent of a system’s maximum power output can be generated using only half or less of the maximum membrane area. Leonardo Banchik, a graduate student in MIT’s Department of Mechanical Engineering, says reducing the size of the membrane needed to generate power would, in turn, lower much of the upfront cost of building a PRO plant.  READ MORE »

Drainage Deal Imminent?

Wed, 08/20/2014 - 09:40
A tentative agreement is near in secret talks between the U.S. Bureau of Reclamation,the U.S. Justice Department and the Westlands Water District to settle three long-simmering drainage lawsuits, according to Interior Department sources. The settlement could be a bonanza for Westlands, which has been searching for half a century for a solution on how to safely dispose of farm drainwater containing salts, heavy metals and the trace element selenium. Westlands drainage triggered deformities in birds at evaporation ponds at the Kesterson National Wildlife Refuge in Merced County more than 30 years ago. According to one source, Westlands will only have to retire a minimum amount of selenium-tainted soils even though a safe drainage solution has not been achieved. A current Reclamation plan to reduce or eliminate toxic drainwater will cost an estimated $2.7 billion for Westlands' 600 growers. Geologists say more than 300,000 acres of land in Westlands and adjacent water districts (state and federal) have elevated levels of selenium, a trace element highly toxic to birds and fish. Environmentalists have called for a cessation of farming on these tainted soils.  READ MORE »

A note from Lloyd

Wed, 08/13/2014 - 10:23

Attention website visitors:  You may have noticed production has dropped off sharply on this website.  The reason is I have had some health problems recently coupled with being out of town a lot. However, my radio show, "Down in the Valley" will air tomorrow at 1 p.m. on KFCF 88.1 FM.  You can listen live streaming at www.kfcf.org.  My guest will be Bakersfield Californian columnist Lois Henry, who writes frequently about water issues in her neck of the woods.   Stay tuned.

Radio show tomorrow, July 10, 2014

  A note from Lloyd:

  On Thursday, July 10, at 1 p.m. on KFCF radio, Fresno, I will interview Loren Wood, overseer of the Harlan P. Kelsey Arboretum, on my monthly radio show.  If you are in the Fresno area, you can hear the show at 88.1 FM.  You can hear it live streaming on the internet at www.kfcf.org.

   Mr. Wood, who holds a master's degree from Harvard University and is the overseer of the Kelsey Arboretum, contends that Kelsey was the East Coast counterpart of John Muir and was an acclaimed native plant horticulturalist as well as a driving force in the establishment of several national parks in the Eastern U.S.  Wood has written a book entitled  "Beautiful Land of the Sky."

  Tune in if you get a chance.
