The duration of floods can be determined by river flow, precipitation and atmospheric blocking. Now an international team of researchers led by Nasser Najibi and Naresh Devineni at The City College of New York is offering a novel physically based Bayesian network model for inference and prediction of flood duration. The model also accurately examines the timescales of flooding.
In Oregon's fertile Willamette River Basin, where two-thirds of the state's population lives, managing water scarcity would be more effective if conservation measures were introduced in advance and upstream from the locations where droughts are likely to cause shortages.
Researchers have developed a new computer model for calculating the water content of snowpacks, providing an important tool for water resource managers and avalanche forecasters as well as scientists.
Coral bleaching is not just due to a warming planet, but also a planet that is simultaneously being enriched with reactive nitrogen from sources like improperly treated sewage, and fertilizers. Nitrogen loading from the Florida Keys and greater Everglades ecosystem caused by humans is the primary driver of coral reef degradation in Looe Key. These coral reefs were dying off long before they were impacted by rising water temperatures. Elevated nitrogen levels cause phosphorus starvation in corals, reducing their temperature threshold for bleaching.
A UW team has discovered thriving communities of bacteria in Alaskan 'cryopegs,' trapped layers of sediment with water so salty that it remains liquid at below-freezing temperatures. The setting may be similar to environments on Mars, Saturn's moon Titan, or other bodies farther from the sun.
Chaco Canyon, a site that was once central to the lives of precolonial peoples called Anasazi, may not have been able to produce enough food to sustain its estimated population numbers.
They found that ice slides over the bedrock much more than previous theories predicted of how ice on the Greenland Ice Sheet moves.
Pavements, which are vulnerable to increased temperatures and excessive flooding due to sea level rise, can crack and crumble. Climate change can be a major contributor and as greenhouse gas emissions continue these issues are projected to accelerate. Researchers at the University of New Hampshire say because of this one of the best ways to extend the life cycle of roads, and keep future costs down, is to increase the thickness of asphalt on certain roads.
An integrated system seamlessly harnesses sunlight to cogenerate electricity and fresh water.
Dolomite is widely in the metal industry as a fireproof material and in construction, such as for joint grouting in panel building. Of course, dolomite is also known as a collector of hydrocarbons.
