      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 ...
    • Observed installation effects of vibro-replacement stone columns in soft clay 

      Egan, D.; Scott, W.; McCabe, Bryan A. (National University of Ireland Galway, 2008-09-03)
      The installation of vibro replacement stone columns in any soil causes significant changes to the stress regime around each probe location. In soft clays, the principal effects are caused by a cavity expansion mechanism ...
