    Whitney, Warren James (Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2002)
    This thesis aims to examine in detail a variety of possible strategies for the development of the Irish access transport system. The Irish access transport system is considered as being the system (passenger and freight) ...
  • The hydrogeology and restoration of a raised bog 

    Regan, Shane (Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)
    The occurrence of ecological communities of conservational value on the surface of raised bog wetlands requires that specific hydrological conditions are maintained. The management of raised bogs, as active peat-forming ...
  • The hydrology and hydroecology of turloughs 

    Naughton, Owen (Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2011)
  • The influence of lubricant slurries on skin friction resistance in pipe jacking 

    Reilly, Ciaran C. (Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2014)
    The use of bentonite and polymer slurries as lubricants to reduce jacking force has long been established practice in pipe jacking and microtunnelling, with reductions in the skin frictional resistance component of jacking ...
  • The influence of particle size on the nature and transport of sediments and associated pollutants in urban stormwater drainage 

    Morgan, David Thomas (Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2014)
    The sediment and pollutant load transported by pipe and gully stormwater drainage systems was investigated through field sampling of a number of urban catchments. Stormwater runoff from a residential catchment was monitored ...
  • The modelling of electric vehicle driving cycles, usage patterns and an investigation of the environmental and economic impacts of electric vehicles 

    Brady, John (Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)
    The European Union has set a number of policy objectives to achieve a sustainable energy fiiture through measures to tackle climate change and to ensure energy security. Electricity as fuel for vehicle propulsion offers ...
