America’s Most Endangered Rivers report is one of the most effective tools in the environmental movement for publicizing threats to rivers and galvanizing the public to take action. The 2013 report highlights a number of key threats, and shines the spotlight on rivers running dry because of outdated water management, wasteful water use, and persistent drought.
River conservation is ‘blind’ without high-resolution monitoring
Scientists from the University of Portsmouth have been investigating nutrient concentrations in the Upper River Itchen, in Hampshire, UK, on behalf of Salmon & Trout Conservation (S&TC) to better understand where phosphorus is coming from and how it is impacting river ecology. The work has been ongoing for over three years and Lauren Mattingley, Science Officer for S&TC says: “Continuous monitoring of phosphorus has improved our understanding of nutrient dynamics in the Itchen. So far, the...
Replacement of Sakonnet River Bridge - Case Study
Location: Tiverton-Portsmouth, Rhode IslandClient: Cardi CorporationThe project consisted of the installation of foundation support systems for the Sakonnet River Bridge Project which included furnishing and installing approximately 7,338 LF of 72” pipe piles within the Sakonnet River, as well as, furnishing and installing approximately 51,525 LF of H-Section Steel Piles for the land-based foundations. The installation of the 72” pipe piles required the design and construction of substantial falsework...

Three separate water leaks located over a distance of 826m using the AQUASCAN TM2 - Case Study
Introduction Locating leaks on large diameter water mains can be very difficult due to poor sound propagation and increased distances between fittings that can be used to perform correlations from. For a correlator to highlight a potential leak each sensor must be able to receive the signal from that leak. Once a correlation is highlighted it is then down to the software and the user of the software to accurately pinpoint the potential leak as the noise created by the leak may not be heard from the surface due...
This Machine Can Make Gallons of Fresh Drinking Water Right Out of Thin Air
(CNN)Machines designed by a California-based team can produce, in some cases, up to 300 gallons of fresh drinking water a day by pulling it straight from the air. And the team just won a $1.5 million prize for it. David Hertz, one of leaders of the Skysource/Skywater Alliance, says he’s excited about what the Skywater machines could do for people living in parts of the world where water is becoming more scarce. “I’ve just been very, very interested in water … but also the...
