      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 ...
    • Multiphase numerical modelling of hydraulic structures with rapidly rotating flows: Stormwater vortex hydrodynamic separator 

      Mullligan, Sean; McDermott, Dermot; Clifford, Eoghan (Conferences and Events at DigitalCommons@USU, 2018-05-15)
      Hydraulic structures exhibiting strongly rotating flows are widely applied in the field of urban and wastewater hydraulics. Given demographic, urban development and climate change challenge, such infrastructure will require ...
    • 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 ...
    • Numerical simulation and assessment of the effects of inlet configuration on the flushing time of a potable water service reservoir 

      O'Neill, Colin J.; Nash, Stephen; Clifford, Eoghan; Mullligan, Sean (Conferences and Events at DigitalCommons@USU, 2018-05-15)
      Service reservoirs provide the dual function of balancing supply with demand and providing adequate pressure in the water supply network by maintaining sufficient pressure head. In a potable water service reservoir, the ...
    • A numerical study of factors affecting the performance of stone columns supporting rigid footings on soft clay 

      Killeen, Michael M.; McCabe, Bryan (Taylor and Francis, 2010)
      The Vibro Replacement technique is now frequently used as a means of improving the bearing capacity and settlement performance of soft cohesive soils. In this paper, a parametric study using the finite element method is ...
    • Numerical study of FRP reinforced timber members subjected to variable climates 

      O'Ceallaigh, Conan; Harte, Annette M. (SHATiS International Conference on Structural Health Assessment of Timber Structures, 2019-09-25)
      The use of FRP reinforcement, even in small percentages, has been shown to improve the short-term flexural behaviour of timber members. This technology has been successfully used in new construction and in the repair and ...
    • Nutrient dynamics in Cork Harbour 

      Nash, Stephen; Hartnett, Michael (2005)
      Estuaries are commonly characterised by high productivity due to frequent if not continuous inputs of nutrients from domestic and industrial discharge effluents and from freshwater and marine sources. These forms of nutrient ...
    • Parameterization of turbulence models using 3DVAR data 

      Olbert, Agnieszka Indiana; Nash, Stephen; Hartnett, Michael (City University of New York, 2014-01-08)
      In this research the 3DVAR data assimilation scheme is implemented in the numerical model DIVAST in order to optimize the performance of the numerical model by selecting an appropriate turbulence scheme and tuning its ...
    • A Performance Assessment Protocol for Structured Mesh Multi-Scale Models 

      Nash, Stephen; Hartnett, Michael (2011)
      Nesting techniques are used to develop multi-scale models giving higher resolution and thus greater accuracy in nested domains. The assessment of model accuracy is therefore important for the successful implementation of ...
    • Presence of emerging contaminants in treated sludges and their potential impacts on the environment 

      Healy, Mark G. (NUI Galway, 2018-11-13)
      Landspreading of sewage sludge remains the most economical and practical means for its disposal, with some countries, such as Ireland, disposing up to 90% to land. Its nitrogen, phosphorus and metal content make it an ...
