  • Mechanisms of flooding in Cork City 

    Olbert, Agnieszka Indiana; Comer, Joanne; Nash, Stephen; Hartnett, Michael (International Association of Hydrological Sciences, 2015-11-17)
    Flooding is one of the most frequent and devastating natural disasters. Many urban developments are located in estuaries where river flow and sea water merge. Cork City situated in the River Lee estuary frequently subject ...
  • Methodology for quality checks for energy efficient buildings 

    Hajdukiewicz, Magdalena; Goggins, Jamie; Keane, Marcus M. (NUI Galway, 2017-03-01)
    The built environment accounts for more than 40% of the overall energy consumption and 36% of the overall CO2 emissions in Europe. Moreover, statistics show that construction and the upkeep of European buildings and ...
  • A nested hydrodynamic model incorporating flooding and drying 

    Nash, Stephen; Hartnett, Michael (2009)
    A one-way nested version of the hydrobiological model DIVAST (Depth Integrated Velocity and Solute Transport) is introduced. The nested model allows flooding and drying of intertidal areas, a process often present in areas ...
  • A nested version of the combined hydrodynamic and water quality model, DIVAST 

    Nash, Stephen (2007)
    The present research deals with the development of a one-way nested version of the combined hydrodynamic and water quality model DIVAST (Depth Integrated Velocity and Solute Transport). Initial research has concentrated ...
