Mapping Plant Stress
2012-12-06 18:06:13

Brett Smith for redOrbit.com — Your Universe Online [ Watch the Video: The Evaporative Stress Index ] This past summer, American farmers watched helplessly as billions of dollars worth of crops succumbed to drought conditions. In an effort to mitigate the adverse effect of future droughts, scientists at NASA and the National Oceanic and Atmospheric Administration (NOAA) are looking to measure and track a potential bellwether of crop conditions: plant stress. Healthy plants...

Using Math To Better Understand River, Valley Networks
2012-12-06 16:23:13

Lee Rannals for redOrbit.com — Your Universe Online Researchers wrote in a paper published in the Proceedings of the National Academy of Sciences (PNAS) that they have used math to explain different characteristics of river and valley networks. Rivers and valleys form intricate branching patterns, which have inspired some scientists to develop a theoretical understanding of river-network geometry. MIT scientists have created a mathematical theory to discover a common...

Where Did Our Winters Go?
2012-12-04 14:19:49

National Science Foundation Changes in winter hydrology, ecology and biogeochemistry are focus of session at American Geophysical Union (AGU) conference If you're planning to skate on a frozen lake or river this winter, ski on a snowy slope, or, when spring arrives, depend on snowmelt to refill your water supply, you may need to think twice. Winter as a "species" may have evolved to be less like the winters we remember. The change has consequences for summer, too, including plants'...

World’s Largest Artificial Watershed Has First Rain
2012-11-30 11:23:00

University of Arizona The Landscape Evolution Observatory, manmade hillsides inside the University of Arizona´s Biosphere 2, provides researchers with the first opportunity to study how water, microbes, soil and plants interact in a setting realistic enough to improve global climate models for years to come. Rain in Southern Arizona is scarce and precious to begin with, but the afternoon shower that soaked the soil 25 miles north of Tucson on Nov. 29 was unusual in several ways....

Australia should prepare now for dry times ahead by ℠banking´ its water underground when rainfall is plentiful, according to an important new scientific study. "There is enormous national potential to store surplus water in aquifers, ensuring sufficient water is available for cities, homes, industry, farming and the environment when drought strikes", says researcher Andrew Ross of the National Centre for Groundwater Research and Training (NCGRT). “We need to start...

Conserving Water Without Hurting The Peach Production
2012-11-21 14:46:28

U.S. Department of Agriculture U.S. Department of Agriculture (USDA) scientists are helping peach growers make the most of dwindling water supplies in California's San Joaquin Valley. Agricultural Research Service (ARS) scientist James E. Ayars at the San Joaquin Valley Agricultural Sciences Center in Parlier, Calif., has found a way to reduce the amount of water given post-harvest to early-season peaches so that the reduction has a minimal effect on yield and fruit quality. ARS is...

Storm Surge Defense Alternatives Needed To Protect Coastal New York
2012-11-20 16:31:34

Lee Rannals for redOrbit.com — Your Universe Online New storm surge barriers are being proposed to help protect Lower Manhattan in New York City from storms such as those like the recent Superstorm Sandy. Catherine Seavitt Nordenson, associate professor of landscape architecture in CCNY's Spitzer School of Architecture, is calling for the deployment of a storm surge strategy that combines elements of soft infrastructure with the hardening of existing infrastructure like the...

Drought Index Calculations Are Flawed
2012-11-18 05:54:28

redOrbit Staff & Wire Reports - Your Universe Online Reports claiming that the climate change has caused global drought conditions to intensify over the past several decades are flawed and based on faulty calculations, according to a new study published Thursday in the journal Nature. According to Anna Salleh of ABC News Australia the researchers report in their study that the 2007 4th Assessment Report (AR4) by the UN Intergovernmental Panel on Climate Change (IPCC) "overestimated"...

Previous Predictions Of Groundwater Flooding Doubles With Future Sea Level Rise
2012-11-12 11:08:42

University of Hawaii “‘ SOEST Scientists from the University of Hawaii at Manoa (UHM) published a study today in Nature Climate Change showing that besides marine inundation (flooding), low-lying coastal areas may also be vulnerable to "groundwater inundation," a factor largely unrecognized in earlier predictions on the effects of sea level rise (SLR). Previous research has predicted that by the end of the century, sea level may rise 1 meter. Kolja Rotzoll, Postdoctoral...

BEIJING, Nov. 1, 2012 /PRNewswire-FirstCall/ -- Tri-Tech Holding Inc. (Nasdaq: TRIT), which provides turn-key water resources management, water and wastewater treatment, industrial safety and pollution control solutions, announced today that it has secured contracts for flash flood early warning and small river hydrologic monitoring projects in two provinces in China. The projects total approximately $1.42 million (approximately RMB 8.95 million). (Logo:...

Endorheic Basin
2013-04-18 22:40:14

An endorheic basin, from the Ancient Greek endon, meaning “within” and rhein, meaning “to flow”, is a closed drainage basin that holds onto water and does not allow outflow to other external bodies of water, such as oceans or rivers, but joins instead into lakes or swamps, seasonal or permanent, that equilibrate via evaporation. Basins such as these might also be referred to as closed or terminal basin or as internal drainage systems. Usually, water that has built up in a drainage...

January 2012: Started out dry as the area only received 1.06in of rainfall which is about .76in below normal leading to an annual deficit of .76in. February 2012: Followed in January’s footsteps as being dry again; the area got only .99in of rainfall which lead to the annual deficit becoming 1.01in. March 2012: The area received a nice welcoming 3.29in of rainfall on the month which is about 1.92in above normal and brought the annual amount back to a positive 1.08in. April 2012:...

A drainage divide, water divide, divide, or watershed is the line that separates neighboring drainage basins. In flat country the divide may be invisible (just a notional line on the ground either side of which water starts its journey to different waterways). While, in hilly country, the divide lies along peaks and ridges. Drainage divides are important geographical, and sometimes political boundaries. Roads and railways often follow divides to minimize slopes and marshes and rivers....

The water cycle (or hydrologic cycle) describes the continuous movement of water above, below, and on the planet. Since the water cycle is in fact a "cycle", there is no beginning or end. Water exists in three states: liquid, vapor, and ice. Although the balance of water on our planet is fairly constant, individual water molecules may come and go. The water cycle is driven by the sun. The sun heats the oceans and allows water to evaporate into the air. The sun also heats snow and ice which...

Environmental Science
2014-01-12 00:00:00

Environmental science is a science that contains a wide range of scientific disciplines. These disciplines are grouped together based on the natural environment which they encompass and interact with. These sciences include physical, chemical, and biological components. Environmental science provides an interdisciplinary approach to the study of the environmental systems. The most common way environmental science is studied is through the work of one individual or small team drawing on the...
