  • How a Specialized Automatic Control Valve Solved Flooding

    The Colombian area of Antioquia creates much of its clean power from hydropower plants along the Guadalupe River. The Guadalupe IV hydroelectric plant generates power with three vertical axis turbines that discharge water below the river level. To prevent flooding, however, the plant needed a solution that ensured the ejector ...

  • From Drought To Flooding: California Struggles With Turnaround

    In a drastic about-face, California has gone from historically desperate drought conditions to an inundation of water that has brought its own set of problems.  In one indicator of the dramatic difference, snowpack on the Sierra mountains recently measured 135 percent of its seasonal average. “We haven’t seen an event of this magnitude in at least a decade,” Mike ...

  • Room for the River as an anecdote to Europe’s flood woes

    As part of a training course on river restoration sponsored by the RESTORE project, I recently visited the Waal River, a main branch of the Rhine River, flowing through the Netherlands. Here the Dutch are making ‘Room for the River’, restoring floodplains to reduce the risks of floods and creating benefits for people and nature. On the heels of recent ...

  • Flood Alleviation

    BritishFlora helps rescue lost London river from subterranean obscurity in award winning flood prevention. In the 1930's, engineers at the then Metropolitan Borough of Woolwich diverted a flood-prone section of the River Quaggy through an underground culvert so that new housing could beQuaggy built. In fine weather, the river was contained. But after heavy rainfall, the Quaggy became a ...

  • Using Electromagnetic induction to characterize soils - Case Study

    Electrical conductivity measurements have been used for years to determine salinity and moisture in soils. Probes were inserted directly into the soil to determine how well the soil conducted an applied current. This process was slow and labor-intensive and was usually reserved for scientific studies. A more recent technique for measuring conductivity is electromagnetic induction (EM), a ...

  • Modelling and Managing Flood Risk and Flooding

    The UK’s prestigious Royal Society recently held a discussion group on the subject of Flood Management and Climate Change. With much of the Northern Hemisphere approaching the winter flooding season, we spoke to Wallingford Software’s David Fortune to find out the role of modelling in flood forecasting and flood management. He set out his ideas as follows: We must remember first that, while we ...

  • Hydrology and flood probability of the monsoon-dominated Chindwin River in northern Myanmar

    As the third largest river of Myanmar, the Chindwin River has great importance as a water resource and transport artery. At 113,800 km2 the basin is comparable in size to the Elbe basin in Europe, although with higher rainfall and runoff. During the southwest monsoon high rainfall intensities with spatial and temporal variation causing severe floods are threatening the region. The study aims to ...

  • Impact of climate change on flood and drought events in Huaihe River Basin, China

    The impact of climate change on floods and droughts in Huaihe River Basin is studied using a coupled land-surface hydrology model and continuous wavelet transform technique. Observed temperature in the basin has increased by approximately 0.228 °C per decade since 1951. Observed precipitation and simulated and observed streamflows are used to grade flood and drought events. Two composite grading ...

  • Colorado River Floods, Droughts, and Shrimp Fishing in the Upper Gulf of California, Mexico

    Abstract  Accurate procedures that measure hydrologic variability would have great value for evaluating ecosystem impacts of upstream water use in the Colorado River Basin. Many local extractive income-based stakeholders rely directly or indirectly on ecosystem health and are adversely affected when the river does not flow. This study focuses on the impact of little or no Colorado River ...


  • Potential analysis for synergetic flood retention measures in the Wandse River catchment

    The Wandse has a total length of 21,5 km with a catchment area of 88 km2. The source is located in Schleswig-Holstein where the upper part of river and catchment (aprox. 4,2 km and 20 km2) are of predominantly rural character. The lower part on Hamburg territory (approx. 17,3 km and 68 km2) is of urban character with a high percentage of sealed surfaces that drain to the Wandse or their ...

  • Are embankments a good flood control strategy? A case study on the Kosi river

    Whether embankments should be used to control floods is a question of great importance in the eastern Gangetic plain, where embankment breaches cause severe flood damage every year and huge damage due to major breaches every few years. Critics of the embankment policy have called for a strategy of living with floods by building dispersed infrastructure to cope with floods. However, no ...
