  • Transient tests for locating and sizing illegal branches in pipe systems

    In pipe systems illegal branches can take away remarkable water resources with negative effects from both the economic and technical points of view. Difficulties in pointing out illegal branches by means of steady-state pressure and discharge measurements are mainly due to the fact that, of course, such systems are not active according to a regular time schedule. In this paper the possibility of ...

  • Preventing rain water flooding case study

    SmartScan 50 helps preventing rain water flooding by providing an efficient level measurement solution in a pop. 1M city. The municipality has been struggling for years with heavy flooding of rain water during winter time that damaged large parts of the city and caused distress to its residents. As a result, a long drainage pipe was laid between the city's shore and the flooded parts. This huge ...

  • Towards a European Integrated Map of Risk From Weather Driven Events: A Contribution to The Evaluation of Territorial Cohesion in Europe

    The last couple of decades have experienced a significant increase of impacts of events driven by extreme weather conditions. There are several concurrent causes for this trend, which is confirmed at both global and European levels. From one side, it is now widely accepted in the scientific community that there is an increased frequency of extreme events due to on-going climate transformations ...


  • Stevens Equipment Records Historical Information During Tsunami

    One of the longest lived products in water resource monitoring has been the Stevens’ chart recorder. In fact, the chart recorder, originally invented by Stevens’ founder and namesake J.C. Stevens in 1911, is the product that established Stevens’ leadership in the water monitoring business.  It’s no surprise then that some of these chart recorders have had long service lives and have recorded ...

  • Torque about improving handling accuracy

    Dry bulk handling is en route to becoming a precision science with a level of control previously undreamt of, thanks to 20 years of research and development into digital non-contact torque monitoring. Dry bulk handling is following many other industrial processes that have been redeveloped from a ‘black art’ to a highly accurate and controlled procedure. A generation ago much of industry was in ...

  • How mangroves help in reducing flooding and coastal erosion

    Inhabitants of low lying delta areas are particularly exposed to flooding and erosion caused by storms and hurricanes. These pressures increase with climate change and sea level rise. Coastal wetlands, such as mangroves, can play a key role in damage mitigation during disasters, as well as in stabilising coastlines. They also contribute to aquaculture and fisheries. Integration of ecosystem-based ...

  • Mangroves for coastal defence

    The role of mangroves in protecting our coasts against natural hazards such as storms, tsunamis and coastal erosion has been widely promoted. But the supposed coastal protection services of mangroves have also been subject to debate. The Nature Conservancy and Wetlands International together with the University of Cambridge set out to map the current state of knowledge about the role of mangroves ...

  • Safety: mischief, mishap or mayhem

    Over the past decade there have been numerous organisational disasters that have caught the attention of the public, no more so than the recent disaster involving the Russian Submarine Nerpa in which 20 people died as result of a Freon gas release. This raises the question: are such incidents the result of freak mishaps and individual mischief or does safety culture offer an explanation as to why ...

  • Engineers torque technology to medics

    Medical experts and sports scientists are becoming increasingly reliant on engineers as their disciplines become more and more technical. Mark Ingham looks at some of the projects his company, Sensor Technology, has helped behind the scenes.

  • Is The `Beep` Noise Pollution?

    It is rare these days that you can be somewhere without noise pollution intruding on some level. Many natural noises may be welcome; a dawn chorus or waves breaking on the beach, but when it comes to man-made decibels it’s a different matter. Never mind the sounds of cars, ring tones and other noises that we take for granted, have you ever noticed how utterly surrounded we are by the humble ...
