West of Lake Powell, along the Utah-Arizona border, lies a sparsely populated territory of high desert, deeply scored canyons and barren mesas. Here, Utah officials want to build a 140-mile-long pipeline to bring precious Colorado River water west to the thriving town of St. George, in the state s far southwestern corner.
In an era of perennial drought, when the future of the Colorado River watershed, the lifeline of the U.S. Southwest, is the subject of fierce debate in state capitols across the region, the idea of bringing more than 26 billion gallons of water a year to a community of fewer than 200,000 people on the edge of the Mojave Desert strikes many as folly. To officials in Washington County, of which St. George is the county seat, though, it is a critical resource for the future.

Past ‘mega droughts’ have often struck simultaneously sites currently home to electricity production along Asian rivers, says the largest study of the continent’s river systems that could help predict long-term changes in the region’s water cycle.
The study, published in the journal Water Resources Research, noted that the findings have important implications for water management and energy production, especially when a country’s economy relies on multiple river basins.
“Our data shows that ‘mega droughts’ have affected multiple power production sites simultaneously, so that we can now use this information to design a grid that is less vulnerable during extreme events, ”said study co-author Stefano Galelli of Singapore University of Technology and design (SUTD).

Largest Study Of Asia s Rivers May Help Predict Changes In Region s Water Cycle: Scientists

Mega-droughts of the past have often simultaneously hit sites that are currently home to power production along Asian rivers, says the largest study of the continent s river systems which may help predict long term changes in the region s water cycle.

Tree rings show evidence of droughts, floods along Potomac River
Tree rings in the Potomac River watershed show evidence of severe droughts and floods over the last 350 years – and scientists can pinpoint the years of those events well enough that they align with writings from people that include Thomas Jefferson.
The findings, published earlier this month in the journal Water Resources Research, could help water managers predict water shortages and floods in Washington, D.C.
“We’ve got these Jefferson quotes and other qualitative records – we have somebody saying the drought was really bad,” said Jim Stagge, lead author of the paper and an assistant professor of civil, environmental and geodetic engineering at The Ohio State University. “But as an engineer, the next question is, how bad was it in terms of numbers? That’s what we wanted to find out. Because if we know how bad it was, we might be able to predict how bad it could be in the future.”
