Adaptive Mesh Multi-Scale Modelling of Tidal Hydraulics and Material Transport
Nash, Stephen; Hartnett, Michael (2011)Multi-scale modelling for structured meshes is achieved by nesting high resolution grids within lower resolution grids. By specifying high resolutions in areas of interest only, computational cost can be reduced. Adaptive ... -
An adaptive mesh solute transport model
Nash, Stephen; Hartnett, Michael (2009)An adaptive mesh solute transport model is presented. The adaptive mesh scheme is implemented in a one-way multiply nested version of the hydrobiological model DIVAST (Depth Integrated Velocity and Solute Transport). The ... -
Analysis of jacking force data for microtunnels in glacial till at Kilcock, Ireland
Curran, Brien G.; McCabe, Bryan A. (IOS Press, 2011)Although the application of microtunnelling to pipeline construction has grown considerably in Ireland in recent times, there is very little published guidance on the jacking forces that might be expected in Irish ground ... -
Analysis of microtunnel jacking forces in alluvium and glacial till in Mullingar, Ireland
McCabe, Bryan; Reilly, Ciaran C.; Orr, Trevor L. (2012)The number of successful microtunnelling drives completed in Ireland is growing rapidly. However, current jacking force predictions rely on experience from the UK and beyond, often gained through work in soils with a small ... -
An analytical approach for the prediction of single pile and pile group behaviour in clay
Sheil, Brian B.; McCabe, Bryan A. (Elsevier, 2016-02-21)In this paper, the 't-z method' is employed to describe the nonlinear behaviour of a single pile and is used to obtain simplified predictions of pile group behaviour by considering the interaction between two-piles in ... -
Appraising stone column settlement prediction methods using finite element analyses
Sexton, Brian G.; McCabe, Bryan A.; Castro, Jorge (Springer Verlag, 2014-09-26)Numerous approaches exist for the prediction of the settlement improvement offered by the vibro-replacement technique in weak or marginal soil deposits. The majority of the settlement prediction methods are based on the ... -
Assessing capital investment on energy improvement projects from a global energy management perspective: a tri-generation case study
Coffey, Ronan; Coakley, Daniel; Sterling, Raymond; Finnerty, Noel; McDonagh, Shane; Keane, Marcus M. (NUI Galway, 2016)For multi-national companies, assessment of energy improvement projects across a global site-base requires a thorough understanding of the driving factors affecting energy consumption on each site. Traditionally, assessment ... -
The assessment of embodied energy in typical reinforced concrete building structures in Ireland
Goggins, Jamie; Keane, Terasa; Kelly, Alan (2010)This paper demonstrates that by understanding how energy is consumed in the manufacturing of reinforced concrete, designers can significantly reduce the overall embodied energy of structures. Embodied energy of products ... -
Assessment of intermittently loaded woodchip and sand filters to treat dairy soiled water
Murnane, J. G.; Brennan, R. B.; Healy, Mark G. (IWA Publishing and Elsevier, 2016-07-31)Land application of dairy soiled water (DSW) is expensive relative to its nutrient replacement value. The use of aerobic filters is an effective alternative method of treatment and potentially allows the final effluent to ... -
Assessment of Tc-99 monitoring within the western Irish Sea using a numerical model
Olbert, Agnieszka Indiana; Hartnett, Michael; Dabrowski, Tomasz (Elsevier ScienceDirect, 2010-05-26)Water circulation patterns and associated material transport within a highly dynamic system such as the Irish Sea are complex phenomena. Although Tc-99 monitoring programme undertaken by the Radiological Protection Institute ... -
Axial load behaviour of a driven cast in situ pile in sand
Flynn, Kevin N.; McCabe, Bryan A.; Egan, Derek (GeoEngineer, 2013)[No abstract available] -
Biaxial loading of offshore monopiles: numerical modelling
Sheil, Brian B.; McCabe, Bryan A. (American Society of Civil Engineers, 2016-05-18)In this study, finite-element (FE) modeling was used to examine the influence of biaxial lateral loading of a monopile foundation. Two different soil models were adopted to investigate the influence of state-dependent and ... -
Carbonation in stabilised peat: an accelerated pilot study
Duggan, Alan R.; McCabe, Bryan A.; Clifford, Eoghan; Goggins, Jamie (ICE Institution of Civil Engineers, 2015)Due to stringent environmental regulations, embodied carbon estimates are being used increasingly to assess the environmental impact of major building and infrastructure projects, including their geotechnical components. ... -
Characterization of separated pig manure composted with a variety of bulking agents at low initial C/N ratios
Troy, Shane M.; Healy, Mark G.; Kwapinski, Witold (2011)The aim of this study was to investigate the composting of separated pig manure solids with or without a variety of bulking agents at a low initial C/N ratio (12.5-23.3). Compost stability was investigated using an oxygen ... -
Creep improvement factors for vibro-replacement design
Sexton, Brian G.; Sivakumar, Vinayagamoothy; McCabe, Bryan A. (ICE Publishing, 2017-02)Although the vibro-replacement stone column technique is being deployed increasingly in soft cohesive soil deposits in which creep settlements may be significant/dominant, the majority of existing stone column settlement ... -
Cyclic loading tests on sandstone and limestone shale aggregates used in unbound forest roads
Rodgers, Michael; Hayes, G; Healy, Mark G. (Elsevier, 2009)This study examined the performance of two aggregates subjected to cyclic loading in a large-scale test rig. The two aggregates examined were: (i) a sandstone from Co. Cork, Ireland and (ii) a limestone shale from Co. ... -
Cyclonic circulation in the western Irish Sea in future climate
Olbert, Agnieszka Indiana; Hartnett, Michael; Dabrowski, Tomasz (International Association for Hydro-Environment Engineering and Research, 2011-07-01)The Irish Sea (IS) is a semi-enclosed body of water on the European Continental Shelf and the Western Irish Sea Gyre (WISG) is a characteristic phenomenon of the Sea. The gyre due to its significant effects on the circulation, ... -
Denitrification of a nitrate-rich wastewater using various wood-based media materials
Rodgers, Michael; Mulqueen, John; Healy, Mark G. (2006)This laboratory study examined the use of various wood materials as a carbon source in horizontal flow filters to denitrify nitrate-nitrogen (NO3-N) from a synthetic wastewater. The filter materials were: sawdust ( Pinus ... -
