  • 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 ...

  • Hydrodynamic modelling of a regulated Mediterranean coastal lagoon, the Albufera of Valencia (Spain)

    Coastal lagoon hydrodynamics are strongly influenced by sea water exchange, especially when the connection between the lagoon and the sea is artificially regulated. These situations increase the complexity of the hydrodynamic regime, requiring the use of numerical models to understand their behaviour. Traditionally, one-dimensional models have been used, although in recent years, the development ...

  • The case for automatic weirs

    With hosepipe bans returning to parts of the country this summer, it’s easy to forget the disastrous floods of recent years – unless, of course, you were personally affected. 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 ...

  • Proactive Dredging: A Little Now or a Lot Later

    By Isaiah Helm, Applications Engineer, SRS Crisafulli If public works departments had a list of fun things to do, dredging sediment out of holding ponds would not be on it.  It’s like cleaning the shower in your bathroom.  Whether you make ...

  • Water quality is key to the success of Cardiff Bay

    Water quality has been a central theme in a redevelopment project that began with the creation of the Cardiff Bay Development Corporation in April 1987. This article will examine the role that water quality has played in the remarkable transformation that has taken place in Cardiff and explain how monitoring technology has developed to the stage whereby any person, anywhere in the world, can view ...
