"This report uses the most current information and state of the art scientific methodology to project a range of future supply scenarios in the upper Rio Grande basin," Castle said. "It is a great first step and a call to action for water managers and users in the basin and the partner federal agencies to move forward and develop adaptation to the challenges this study brings to light."
The study was conducted by the Bureau of Reclamation in partnership with Sandia National Laboratories and the U.S. Army Corps of Engineers. It includes a detailed evaluation of the climate, hydrology and water operations of the upper Rio Grande basin of Colorado and New Mexico. Also included is an evaluation of the potential impacts associated with climate change on streamflow, water demand and water operations in the basin.
Temperatures will increase four to six degrees Fahrenheit by the end of the 21st century, according to the climate modeling used in the study. Although the modeling projects that total annual average precipitation in the basin will not change considerably, we are likely to see a decreasing snowpack, an earlier and smaller spring snowmelt runoff and an increase in the frequency, intensity and duration of both droughts and floods.
The models used for the study consistently project an overall decrease in water availability in the basin. Rio Grande supplies are projected to decrease by an average of one-third from current supplies. The water supply from the San Juan-Chama Project, which is imported to the Rio Grande, is projected to decrease by an average of one-quarter.
All of these impacts would contribute to a larger gap between water supply and demand and lead to future water management challenges for the Bureau of Reclamation and other water managers within the upper Rio Grande basin.
The URGIA is the first impact assessment to be completed by Reclamation as part of the Westwide Climate Risk Assessments through the Department of the Interior's WaterSMART Program. Impact assessments are reconnaissance-level investigations of the potential hydrologic impacts of climate change in the major river basins of the Western United States. Through WaterSMART, Reclamation is also able to conduct a more in-depth basin study in conjunction with state and local partners that would develop options and strategies to address supply and demand imbalances.
The WaterSMART Program focuses on improving water conservation, sustainability and helping water resource managers make sound decisions about water use. It identifies strategies to ensure that this and future generations will have sufficient supplies of clean water for drinking, economic activities, recreation and ecosystem health. The program also identifies adaptive measures to address climate change and its impact on future water supply and demand.

Reclamation is the largest wholesale water supplier and the second largest producer of hydroelectric power in the United States, with operations and facilities in the 17 Western States. Its facilities also provide substantial flood control, recreation, and fish and wildlife benefits.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
