  • Water hits and sticks: findings challenge a century of assumptions about soil hydrology

    Researchers have discovered that some of the most fundamental assumptions about how water moves through soil in a seasonally dry climate such as the Pacific Northwest are incorrect -- and that a century of research based on those assumptions will have to be reconsidered. A new study by scientists from Oregon State University and the Environmental Protection Agency showed -- much to the surprise ...

  • Hydrological history improves understanding

    Once lost in the mists of time, the colonial hydrology of the northeast US has been reconstructed by a team of geoscientists, biological scientists and social scientists. The findings provide a new way of uncovering the hydrology of the past and will lead to a better understanding of hydrologic systems now and in the future, the scientists say. The results, which extend as far back as the year ...

  • Hydrological changes imperil world`s poorest regions, say water experts

    Modern agriculture and land-use practices may lead to major disruptions of the world’s water flows, with potentially sudden and dire consequences for regions least able to cope with them, researchers at the Stockholm University-affiliated Stockholm Resilience Centre and McGill University have warned. In a paper published April 1 in the journal Trends in Ecology and Evolution, Dr. Line J. Gordon ...

  • Restoring coastal wetlands? check the soil

    Rising sea levels and coastal development are threatening coastal freshwater wetlands with saltwater intrusion. While most ecosystem restoration projects have focused on surface water and groundwater, new research finds that conditions in the vadose zone, the unsaturated soil below the surface but above the water table, are of particular importance to seedling survival in coastal floodplain ...

  • Is iron from soil a factor in algal blooms?

    Australia's own distinctive red soils could play a part in the formation of the stinking swathes of blue-green algae often shovelled off east coast beaches in summer. A QUT team of scientists is taking an in-depth look at how iron, which gives our iron-rich soil its red colour, reaches water to potentially contribute to the algal blooms, which not only have a foul smell, but also make our eyes ...

  • Sophisticated soil analysis for improved land use

    Soil variation occurs across multiple geographic scales ranging from vast climatic regions of the Earth to a 50 acre farm field to the molecular world of soil nano-particles in a pinch of soil. For example, in a forest or an agricultural field, soil properties vary from the summit of a hill down to the base. Within a single soil aggregate that may be less than a quarter inch in diameter, there ...

  • StormNET by BOSS International approved by Delaware division of soil and water conservation

    The Delaware Division of Soil and Water Conservation has accepted StormNET by BOSS International for use in performing stormwater management calculations in accordance with the State of Delaware’s Sediment and Stormwater Regulations. “We are pleased that StormNET has been accepted by the State of Delaware and that it easily passed their NRCS TR-20 benchmark test,” said Chris Maeder, Senior ...


  • Rik van den Bosch appointed as Director ISRIC – World Soil Information

    Rik van den Bosch (1965) graduated in 1990 from Wageningen University as an Environmental Scientist, with a strong emphasis on soil chemistry, soil physics, hydrology and tropical soil science. Between 1991 and 2007 he worked a.o. for Alterra as researcher and project leader on soil and water management in Africa and Asia. His work initially focussed on integrated soil fertility management and ...

  • Northern US soil carbon reservoirs vulnerable to global warming, says USGS

    Mounting evidence shows that soil carbon is increasingly contributing larger amounts of carbon dioxide (CO2) to the atmosphere as a result of warming, permafrost degradation, and complex climate-biogeochemical interactions. Northern soils are known to harbor large amounts of carbon in the zone between the moss surface and the permafrost or mineral soil boundary. USGS Soil Scientist, Jennifer ...

  • New online portal uses valuable Cranfield soils data

    The UK Soil Observatory (UKSO), a new online portal launched on Friday, provides free access to national UK soils data and its research for those who have an interest in soil and soil related matters. Bringing together valuable data from several institutions across the UK, the portal includes information from Cranfield ...

  • Screening soil moisture conditions reveals an increased risk of drought in a Swedish drainage basin

    The risk of drought in the Norrström drainage basin, Sweden, increased during the 20th century, a new study has found. As the frequency of the dry periods increased, less water was available in the landscape for agriculture and for the resupply of groundwater — despite an increase in precipitation in the area over the same period. The researchers reached this conclusion after screening ...

  • Silixa to present at the American Geophysical Union’s 48th Annual Fall Meeting in San Francisco, California, USA, on 17-18 December, 2015

    Silixa will be presenting at AGU’s Fall Meeting in San Francisco, California, USA on 17 and 18 December, 2015. The first presentation, entitled Challenges in Ecohydrological Monitoring at Soil-Vegetation Interfaces: Exploiting the Potential for Fibre Optic Technologies, will detail the methodological background to a DTS based soil moisture monitoring project carried out in ...

  • Decagon`s environmental stations allow for customized monitoring

    The ability to accurately measure environmental parameters on a local scale is becoming an increasing need worldwide, whether you’re a hydrologist, an environmental researcher, or even a farmer. It is evident now that the environmental conditions and forecasts for one location cannot always be extrapolated for nearby areas. Due to differences in terrain, elevation, and topography, a rain ...

  • Wind, salt and water are leading indicators of land degradation in Abu Dhabi desert lands

    Desert environments are characterized by poor vegetative cover, strong winds, dry, non-cohesive sandy soils, and hyper-arid conditions. In this context, the land resources of Abu Dhabi Emirate in the United Arab Emirates are subjected to various land degradation stresses, including wind erosion, salinization, waterlogging, landfilling, and overgrazing. To sustain the land resources of Abu Dhabi ...

  • 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 ...

  • Climate change pose risks for waste water treatment

    A Simplified Climate Change Impact Assessment Tool (SCIAT) addresses the specific needs of the water industry, translating climate change projections into real-world impacts. A recent study in CIWEM’s Water and Environment Journal demonstrates its application in assessing the impacts of climate change on the reservoir water quality and water treatment plant (WTP) operations at Grafham Water ...

  • MWH Soft FloodWorks successfully predicts flash flooding in Egypt

    MWH Soft, a leading global innovator of wet infrastructure modeling and simulation software and technologies, has announced the successful implementation of its FloodWorks software in a 3900 mi2 (10,000 km2) pilot area around Nuweiba, Egypt. The system was used to successfully predict flooding in the region in February 2010, the worst flash flooding event in Egypt since 1994. The implementation ...

  • Urban trees enhance water infiltration

    Global land use patterns and increasing pressures on water resources demand creative urban stormwater management. Traditional stormwater management focuses on regulating the flow of runoff to waterways, but generally does little to restore the hydrologic cycle disrupted by extensive pavement and compacted urban soils with low permeability. The lack of infiltration opportunities affects ...
