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 ... -
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 ... -
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] -
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. ... -
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, ... -
Development of a global energy management system (GEMS) for the life sciences industry
Finnerty, Noel; Coakley, Daniel; Sterling, Raymond; Keane, Marcus M.; Coffey, Ronan (NUI Galway, 2015-08)For multi-national companies, assessment of cost effective energy efficiency projects across a global site base is a complex problem involving multiple variables. This research project proposes a novel methodology for ... -
Development of a global energy management system for the life sciences industry: an energy management maturity model implementation
Finnerty, Noel; Sterling, Raymond; Coakley, Daniel; Keane, Marcus M. (NUI Galway, 2015-11)The Global Energy Management System (GEMS) research project proposes a novel methodology for assessing capital energy-efficiency projects at a global level. The paper scope covers the systematic development and implementation ... -
Driven cast-in-situ piles in granular soil: applicability of CPT methods for pile capacity
Flynn, Kevin N.; McCabe, Bryan A.; Egan, D. (CBT'14, 2014)Most CPT-based design methods for driven piles are heavily influenced by research on preformed driven piles. In this paper, a critical review is made of the ability of these methods to predict the total capacity of driven ... -
The effects of array configuration on the hydro-environmental impacts of tidal turbines.
Fallon, David; Nash, Stephen (2012)Tidal stream turbines provide a technically viable means of generating electricity from a sustainable resource; however, economic viability will require the deployment of multiple devices in array formations in a manner ... -
Energy transfer ratio for hydraulic pile driving hammers
Flynn, Kevin N.; McCabe, Bryan A. (NUI Galway, 2016-08-29)The ability of hydraulic pile driving hammers to overcome energy losses during freefall enables a greater proportion of the impact energy to be transferred to the pile in comparison to diesel hammers. This percentage, ... -
Experiences of dry soil mixing in organic soils
Timoney, Martin J.; McCabe, Bryan (Institution of Civil Engineers, 2012)Soil mixing, or soil stabilisation, is a method of enhancing the geotechnical properties of suitable host soil through the addition of cementitious and/or pozzolanic binders in either dry or slurry forms. In dry soil mixing, ... -
Factors affecting Embodied Carbon/Embodied Energy associated with ground improvements techniques for construction on peat
Duggan, Alan R.; McCabe, Bryan A.; Goggins, Jamie; Clifford, Eoghan (NUI Galway, 2012)In addition to the traditional drivers of cost and timely programme delivery, embodied energy (EE) and embodied carbon (EC) have emerged as major considerations in all aspects (including geotechnical) of large construction ... -
Galway Bay bathymetry comparison from Admiralty Chart and LiDAR datasets.
Fallon, David; Nash, Stephen (2012)The primary objective of this paper was to test the sensitivity of numerical models to bathymetry datasets. Bathymetric datasets used were from; 1) Admiralty Charts and 2) LiDAR & Multi- Beam Echo Sounder surveys. The ... -
