Factors affecting nitrate distribution in shallow groundwater under a beef farm in South Eastern Ireland
(Elsevier, 2009-07)Groundwater contamination was characterised using a methodology which combines shallow groundwater geochemistry data from 17 piezometers over a 2 yr period in a statistical framework and hydro-geological techniques. Nitrate-N ... -
Field assessment of coconut-based activated carbon systems for the treatment of herbicide contamination
(Elsevier, 2023-12-03)Once released into the environment, herbicides can move through soil or surface water to streams and groundwater. Filters containing adsorbent media placed in fields may be an effective solution to herbicide loss in the ... -
A finite element-based approach for predictions of rigid pile group stiffness efficiency in clays
(Springer Verlag, 2013-08-17)This paper presents a finite element parametric study of several variables that affect the stiffness efficiency of rigidly capped pile groups with a view to developing a solution for preliminary design purposes. Previous ... -
Flipped learning in a civil engineering module: student and instructor experiences
(Irish Learning Technology Association, 2018-08-24)Flipped learning is a form of active learning in which the basic content is assimilated before scheduled classroom sessions, enabling more productive use of classroom time to cultivate problem-solving ability, a key ... -
Formal calibration methodology for CFD models of naturally ventilated indoor environments
(Elsevier, 2012-08-31)Well planned natural ventilation strategies and systems in the built environments may provide healthy and comfortable indoor conditions, while contributing to a significant reduction in the energy consumed by buildings. ... -
A framework for determining unsaturated zone time lags at catchment scale
(Elsevier Masson, 2016-12-10)The responses of waterbodies to agricultural programmes of measures are frequently delayed by hydrological time lags through the unsaturated zone and groundwater. Time lag may therefore, impede the achievement of remediation ... -
Future phosphorus: advancing new '2D' allotropes and growing a sustainable bio economy
(Crop Science Society of America with American Society of Agronomy and Soil Science Society of America, 2019-07-11)With more than 40 countries currently proposing to boost their national bioeconomies, there is no better time for a clarion call for a new bioeconomy, which, at its core, tackles the current disparities and inequalities ... -
Global and local fatigue analysis of X100 and X60 steel catenary riser girth welds
(Taylor & Francis, 2017-08-31)The use of steel catenary risers in offshore oil and gas production has increased significantly in recent years, in particular for deepwater applications. This paper presents a detailed assessment approach with respect to ... -
Greenways as a tourism resource: a study of user spending and value
(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 ... -
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 ... -
Harvesting effects on biomass and nutrient retention in Phragmites australis in a free-water surface constructed wetland in western Ireland
(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 ... -
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 ... -
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 ... -
Hydrodynamic modelling approaches to assess mechanisms affecting the structural performance and maintenance of vortex drops shaft structures
(Taylor & Francis, 2019-07-29)Vortex drop shafts, a key hydraulic structure within modern day deep sewer conveyance systems, must be designed structurally to sustain performance and longevity of operating life under very energetic loading conditions. ... -
Hydrogen sulfide oxidation in novel Horizontal-Flow Biofilm Reactors dominated by an Acidithiobacillus and a Thiobacillus species
(Taylor & Francis, 2016-03-17)Hydrogen Sulfide (H2S) is an odourous, highly toxic gas commonly encountered in various commercial and municipal sectors. Three novel, laboratory-scale, Horizontal-Flow Biofilm Reactors (HFBRs) were tested for the removal ... -
