(Taylor & Francis, 2016-01-18)Cycling is increasingly recognized as a key tool in improving transport sustainability, promoting increased physical activity and improved public health and developing the tourism sector. While the provision of safe and ... -
Ground heave induced by installing stone columns in clay soils
(ICE Publishing, 2013-12)Measurements of ground heave induced by installing stone columns in soft clay are presented in this paper. These measurements are likely to provide guidance to practitioners concerned about the possible impact of column ... -
Ground improvement using the vibro- stone column technique
(Institution of Engineers in Ireland, 2007)The Vibro Stone Column technique is one of the most widely-used ground improvement processes in the world, although its potential for improving Irish sites has yet to be fully exploited. Historically the system has been ... -
Habit suitability assessment of constructed wetlands for the Smooth Newt (Lissotriton vulgaris [Linnaeus, 1758]): a comparison with natural wetlands
(Elsevier, 2017-06-22)Given the current decline of natural wetlands worldwide and the consequent negative impacts on amphibians, wetlands constructed for the treatment of wastewaters have the potential to play a role in the protection of these ... -
Harvesting effects on biomass and nutrient retention in phragmites australis in a free-water surface constructed wetland in western Ireland
(The Royal Irish Academy, 2008-06-26)The aim of this study was to examine the seasonal variation in biomass, total nitrogen (Tot-N) and total phosphorus (Tot-P) content of Phragmites australis in a 3-cell free-water surface (FWS) constructed wetland in western ... -

(2007)The aim of this study was to examine the seasonal variation in biomass, total nitrogen (Tot-N) and total phosphorus (Tot-P) content of Phragmites australis in a 3-cell free-water surface (FWS) constructed wetland in western ... -
Heave-ho! A laboratory model of an underfloor environment incorporating pyritiferous fill
(NUI Galway, 2016)Damage to domestic dwellings in the greater Dublin area of Ireland caused by the expansion of underfloor fill material containing pyrite has become a high-profile national problem in recent years. In this paper, a novel ... -
High-resolution multi-scale modelling of coastal flooding due to tides, storm surges and rivers inflows: A Cork city example
(Elsevier, 2017-01-31)This paper demonstrates the capability of a new state-of-the-art flood modelling system consisting of multiple nested models to simulate urban coastal flood inundation. A flood event in Cork City, Ireland which occurred ... -
Highly innovative building control tools tackling the energy performance gap
(HIT2GAP Consortium, 2018-10-31)The deliverable D6.1 is part of Work Package (WP) 6 with focus on ‘Innovative services definition and market exploitation’. More specifically, it belongs to Task (T) 6.1 named ‘New generation of services based on intelligent ... -
Holistic evaluation of field-scale denitrifying bioreactors as a basis to improve environmental quality.
(Association of Crop, Soil and Environmental Societies (ACSES), 2015-10-02)Denitrifying bioreactors effectively convert nitrate-nitrogen (NO3-N) to di-nitrogen and thereby protect water quality in agricultural landscapes. In the present study, the performance of a pilot-scale bioreactor (50 m ... -
How accurate are Energy Performance Certificates indicated energy savings of building retrofits?
(NUI Galway, 2016-08-29)With the impending nearly zero energy building (NZEB) regulations for residential new builds and retrofits for the European Union (EU) housing stock and the percentage of new buildings relative to existing buildings is ... -
