Digging in the dirt: Researchers develop new methods for assesing risk of subsurface phosphorus

Thu, 17/08/2017 - 15:07
New methods for assessing the loss of phosphorus in soil have now been developed by researchers. While current measurements focus mainly on surface runoff, the new research is looking at the best way to measure the risk of underground phosphorus that winds up in drainage water.

Florida flood risk study identifies priorities for property buyouts

Thu, 17/08/2017 - 14:28
A study of flood damage in Florida proposes prioritizing property buyouts based on flood risk, ecological value, and socioeconomic conditions. Forecasters say an above-normal hurricane season is likely in the Atlantic Ocean this year, while a rising sea level is making Florida increasingly vulnerable to dangerous flooding.

Climate change shifts timing of European floods

Thu, 10/08/2017 - 19:15
A linkage between climate change and floods has been identified using a river flow dataset of unparalleled scale and diversity. This is the first time this link has been demonstrated at a continental scale using observational data.

The only way is up: Trees help reptiles thrive

Thu, 10/08/2017 - 15:49
If graziers leave trees in place on their land, all types of reptiles will benefit, investigators suggest in a new report.

Complex causes of Maldives flooding

Mon, 07/08/2017 - 13:23
The causes of coastal flooding in the Maldives are more complex than previously thought, according to a new study. Researchers examined wave and sea level data around historic flood events and found that multiple factors contribute to flooding in the Indian Ocean island chain, which has an average land elevation of just one meter.

Mangroves vital for environmental decontamination

Thu, 03/08/2017 - 20:58
Mangrove trees, particularly their leaf litter, filter copper out of soil and water in Indonesia.

Benefits of dikes outweigh costs, suggests study

Mon, 31/07/2017 - 16:45
In the first study of its kind, an international team of scientists has concluded, on a global scale, that the economic and long-term benefits of building dikes to reduce flood damage far outweigh their initial cost.

Invasive plant species can enhance coastal ecosystems

Mon, 17/07/2017 - 20:08
Invasive plant species like seaweed can provide vital ecosystem functions in coastal areas where native habitats such as salt marshes and oyster reefs have severely declined. A new study finds that invasive species could be used to offset the loss of native habitats that provide storm protection, food production and other benefits to billions of people.

Mississippi mud may hold hope for Louisiana coast

Thu, 13/07/2017 - 01:11
Mud, the most plentiful sediment type carried by the Mississippi River, may be the most powerful tool in building land to keep up sea level rise, suggests new research.

'Big Muddy' Missouri river needs a plan

Tue, 11/07/2017 - 17:14
As the Missouri River flows across the Great Plains to where it meets the Mississippi River at St. Louis, it accumulates such a large sediment load that it has earned the nickname 'Big Muddy.' A recent study looks at the history of the river, damages and changes from the 2011 flood, and its current post-flood condition. The study concludes that the river needs a comprehensive plan with multi-state cooperation.

Global erosivity map shows differences between climatic regions

Wed, 05/07/2017 - 16:31
The first ever global erosivity map gives new insights into the geography of the rain's impact on soil erosion. The underlying research highlights differences between climatic regions and calls for global action to protect our soils.

Can satellites be used as an early warning system for landslides?

Wed, 05/07/2017 - 14:54
Researchers have been tracking the massive landslide which struck Xinmo Village, Maoxian County, Sichuan Province in China.

Distant earthquakes can cause underwater landslides

Tue, 27/06/2017 - 18:44
New research finds large earthquakes can trigger underwater landslides thousands of miles away, weeks or months after the quake occurs.

Rising seas could result in 2 billion refugees by 2100

Mon, 26/06/2017 - 15:57
In the year 2100, 2 billion people -- about one-fifth of the world's population -- could become climate change refugees due to rising ocean levels. Those who once lived on coastlines will face displacement and resettlement bottlenecks as they seek habitable places inland, according to new research.

Flooding risk: America's most vulnerable communities

Wed, 21/06/2017 - 16:40
Floods are the natural disaster that kill the most people. They are also the most common natural disaster. As the threat of flooding increases worldwide, a group of scientists have gathered valuable information on flood hazard, exposure and vulnerability in counties throughout the US.
