Wave of the future? Dams as river restoration
Society once viewed dams as the wave of the future, providing hydroelectric power, water reserves and controlling floods. Now their removal appears to be the new trend. With removal, new issues begin to emerge, especially concerning river systems and effects upstream and downstream. On August 10, 2001 researchers will gather to explore (2001-08-05)

Guidelines developed for hydraulic design of safer canoe chutes
With the advent of warmer weather, many outdoor enthusiasts are taking to the water in canoes and kayaks. Some boaters, blocked in their travels by one of the myriad dams that dot the nation's waterways, may attempt to navigate the spillway - a dangerous practice that could result in death by drowning in the strong undertow that forms at the base of a dam. University of Illinois scientists have a safer alternative: properly designed passageways called canoe chutes. (2001-04-01)

Engineers form unique consortium for better undergraduate earthquake engineering
It doesn't take a catastrophe on the order of the Seattle or recent India earthquake for civil engineers to realize that earthquake-engineering studies need to be intensified. Washington University in St. Louis civil engineers have formed a unique consortium to indoctrinate young earthquake engineers nationwide in hands-on research early in their undergraduate careers.

The role of science in restoring California's water resources
Few issues in California are as contentious as water. That`s particularly true in Northern California, where snowmelt from the Sierra Nevadas is siphoned off to meet the state's drinking and irrigation needs.

Scientists discover beetle that cures water fern menace
Scientists from Wits University and the Plant Protection Research Institute have developed a cure to one of South Africa's biggest water menaces: the water fern, which has been clogging waterways and suffocating lakes. (1999-06-23)

Alaska's Columbia glacier traveling at record pace
Already the fastest moving glacier in the world, the Columbia Glacier in Alaska has increased its speed from 25 meters to 35 meters per day in recent months, according to a University of Colorado at Boulder glaciologist. (1999-06-16)

Projected snowpack decline could mean drastic changes for Pacific Northwest
Despite this year's record snowfall in the Pacific Northwest, the amount of water stored as mountain snowpack is projected to drop significantly in the long run, a change that could repaint the face of the region and drastically alter how water is used and allocated, according to University of Washington researchers. (1999-06-01)

Researchers Analyze Role Of Shear In Turbine Passage
Although turbines have generated power at hydroelectric dams for more than 100 years, not much is known about how water flowing through the turbines may harm fish. Now, researchers at DOE's Pacific Northwest National Laboratory have begun examining the relationship between water velocities within the turbine chamber and injuries to fish. (1999-05-26)

New England Water Is Improving But Problems Remain, Says New USGS Report
Water quality has improved significantly in New England over the past 50 years because of advances in the treatment of municipal and industrial wastes. However, New Hampshire, Maine, Massachusetts, and Rhode Island are still experiencing some problems with the quality of ground and surface water and the water in the Gulf of Maine. (1999-04-30)

Landsat 7 Starts Viewing The World
The first images, with twice as much detail as previous Landsat satellites, show Florida's panhandle, South Dakota, and a startlingly clear image of a jet contrail and its shadow on the ground. (1999-04-28)

America's Most Powerful Centrifuge Testing Dam Safety At CU-Boulder
In the basement of the University of Colorado at Boulder's College of Engineering and Applied Science, a monstrous centrifuge sporting an 80,000-pound swinging arm and a box to tote hefty payloads whirls a miniature earthen dam at 200 miles per hour. (1999-04-12)

Technologies Track, Map Fish Behavior
Psychology normally isn't associated with fisheries biology, but the behavior of fish could be an important factor in restoring endangered salmon stocks in the Columbia and Snake rivers. Scientists at the Department of Energy's Pacific Northwest National Laboratory have developed tools to study how fish behave and to evaluate fish bypass systems at dams. (1999-02-09)

Architecture Program Aims To Make Buildings More Resistant To Terrorism And Catastrophes
When disaster strikes, people evacuate. That's because the structures that normally protect us -- buildings, bridges, dams, and tunnels -- are often the most dangerous places to be during catastrophes like hurricanes, earthquakes, industrial accidents, or terrorist attacks. Rudy Matalucci, a civil engineer at Sandia National Laboratories in Albuquerque, N.M., wants people to feel compelled to run into buildings rather than out of them during emergencies. (1999-01-26)
