  • The world’s first model for engineered nanoparticles in surface waters

    Researchers of Wageningen University provide the world’s first spatiotemporally explicit model that simulates the behaviour and fate of engineered nanoparticles (ENPs) in surface waters. Wageningen researcher Bart Koelmans: “This is important in order to assure safe nanotechnology. We do need to have an assessment of the risks of ENPs to man and the environment.” ...

  • New model simulates US groundwater and surface water interactions

    A new model to simulate groundwater and surface water interactions has been released by the U.S. Geological Survey (USGS). The groundwater and surface water FLOW (GSFLOW) model simultaneously accounts for climatic conditions, runoff across the land surface, subsurface flow and storage, and the connections among terrestrial systems, streams, lakes, wetlands, and ground water. 'GSFLOW can be used ...

  • Water-shedding surfaces can be made to last

    Original story at MIT News Steam condensation is key to the worldwide production of electricity and clean water: It is part of the power cycle that drives 85 percent of all electricity-generating plants and about half of all desalination plants globally, according to the United Nations and International ...

  • Towards the ultimate model of water

    Water is essential to life as we know it; from its unusual density maximum which preserves freshwater ecosystems by ensuring that ponds freeze from the top down during winter, to its hydrogen bonds which shape proteins and the DNA double helix. But while water (in its liquid, solid and vapour forms) is one of the most common substances on Earth, many of its life-sustaining properties remain a ...

  • Province Announces Manitoba`s First Comprehensive Surface Water Management Strategy

    $320-million Investment to Better Manage Floods, Droughts, Protect Lake Winnipeg; Regulations to Preserve Wetland Benefits; Cut Red Tape for Routine Drainage Projects:  Ministers Manitoba is proposing its first comprehensive Surface Water Management Strategy and multi-year surface water management investments to protect Lake Winnipeg and mitigate flood and drought damage, Conservation and ...

  • The right to water

    The problem is real. The United Nations forecasts that by 2030, nearly half of the world’s population will be living in areas of 'high water stress, and climate change is compounding the problem according to a UN report released to coincide with the Istanbul conference.  Global warming is causing droughts in some areas and floods in others. In Africa alone, between 75 million and 250 million ...

  • Water security in an uncertain world

    Policymakers must find flexible plans to ensure water security despite the uncertainties of climate change, says climate scientist Mark New. Much of the developing world is dependent on rainfall, snow or ice for its natural water supplies, so researchers and policymakers are concerned about how climate change will affect water security. Long-term water availability is largely determined by the ...

  • 3D Model Slicing

    Complex site designs create a real challenge to traditional 2D cross-sectional modeling. Currently, the majority of projects are approached from a strictly 2D point of view. In other words, site data is collected in 3D and a 2D cross-section is interpolated, with much effort, from sifting through the data, and an analysis finally performed for that particular cross-section. A limited number of ...

  • Measuring water from space

    Observations from satellites now allow scientists to monitor changes to water levels in the sea, in rivers and lakes, in ice sheets and even under the ground. As the climate changes, this information will be crucial for monitoring its effects and predicting future impacts in different regions. Sea level rise in one of the major consequences of global warming, but it is much more difficult to ...

  • Ruining the world’s water supply

    Agricultural run-offs containing fertilizers, animal wastes and pesticides are infecting rivers and water courses with blue-green algal blooms and toxic chemicals. While the problem is particularly evident in developing countries - Canada, Australia and the United States contain some of the world’s most polluted rivers, and poor agricultural practices are the root cause. Almost one-fifth ...

  • Pricing policies for efficient water management

    Researchers have developed a new method to investigate the effects of different water pricing policies at the river basin scale. The system is intended to be used when water has to be allocated to different users under conditions of water scarcity. In many parts of the world, demand for water is outstripping the availability of water. Water is increasingly seen as a scarce resource that ...

  • Ocean salinities show an intensified water cycle

    The stronger water cycle means arid regions have become drier and high rainfall regions wetter as atmospheric temperature increases. The study, co-authored by CSIRO scientists Paul Durack and Dr Susan Wijffels, shows the surface ocean beneath rainfall-dominated regions has freshened, whereas ocean regions dominated by evaporation are saltier. The paper also confirms that surface warming of the ...

  • New Discoveries Improve Climate Models

    New discoveries on how underwater ridges impact the ocean's circulation system will help improve climate projections. An underwater ridge can trap the flow of cold, dense water at the bottom of the ocean. Without the ridge, deepwater can flow freely and speed up the ocean circulation pattern, which generally increases the flow of warm surface water. Warm water on the ocean's ...
