  • Free-surface flow simulations for discharge-based operation of hydraulic structure gates

    We combine non-hydrostatic flow simulations of the free surface with a discharge model based on elementary gate flow equations for decision support in the operation of hydraulic structure gates. A water level-based gate control used in most of today's general practice does not take into account the fact that gate operation scenarios producing similar total discharged volumes and similar ...

This year’s harsh winter and modest levels of spring and summer rainfall belie a growing trend of more extreme weather events hitting the UK and a pattern of warmer winters and wetter summers. As we saw ...

  • Excavation, Retrieval, and Off-Site Disposal

    Introduction: Contaminated material is removed and transported to permitted off-site treatment and/or disposal facilities. Some pretreatment of the contaminated media usually is required in order to meet land disposal restrictions. Confined disposal facilities (CDFs) are engineered structure enclosed by dikes and designed to retain dredged materials. A CDF may have a large cell for ...

  • Successful trunk main correlations in Australia, the land of long pipes - Case study

    The Aquasscan TM Successfully locates leaks at distances over 1KM in Sydney. The Gutermann Aquascan (Trunk Main) correlator provided a series of high performance correlations in trials performed in Sydney, Australia.  Sydney Water provided a 1.2 KM of 600mm OD Steel trunk main for a series of tests to be performed to evaluate the performance.  The testing was administered by ...
