Impact of chemical amendment of dairy cattle slurry on phosphorus, suspended sediment and metal loss to runoff from a grassland soil
(2011)Emerging remediation technologies such as chemical amendment of dairy cattle slurry have the potential to reduce phosphorus (P) solubility and consequently reduce P losses arising from land application of dairy cattle ... -
On-farm treatment of dairy soiled water using aerobic woodchip filters
(Elsevier, 2011)Dairy soiled water (DSW) is produced on dairy farms through the washing-down of milking parlours and holding areas, and is generally applied to land. However, there is a risk of nutrient loss to surface and ground waters ... -
Evaluation of chemical amendments to control phosphorus losses from dairy slurry
(Wiley, 2011)Land application of dairy slurry can result in incidental losses of phosphorus (P) to runoff in addition to increased loss of P from soil as a result of a buildup in soil test P (STP). An agitator test was used to identify ... -
Modelling phytoplankton dynamics in a complex estuarine system
(2011)The primary objective of this research was to develop a generic methodology for numerical modelling of the water quality within estuarine systems; in particular, this research focused on modelling nutrient dynamics and ... -
Irish estuaries: Water quality status and monitoring implications under the water framework directive
(2011)The status of water quality of Irish estuaries is reviewed; this sheds light on the rationale behind the design of the national monitoring programme. Relative to other EU Member States, Ireland's coastal monitoring programme ... -
Different depth sand filters for laboratory treatment of synthetic wastewater with concentrations close to measured septic tank effluent
(2011)The objective of this study was to apply hydraulic and chemical oxygen demand (COD) loading rates at the upper limits of the design criteria for buried sand filters to test the sand filter depth design criteria. Over a ... -
Long-term inter-annual variability of a cyclonic gyre in the western Irish Sea
(Elsevier ScienceDirect, 2011-05-26)The western Irish Sea gyre (WISG) is a cyclonic baroclinic flow around a dome of stagnant water which develops each year during the heating season in the western Irish Sea. Research was carried out to determine long-term ... -
Evaluation of chemical amendments to control phosphorus losses from dairy slurry.
(Soil Use and Management, 2011-06-01)The aim of this paper is to identify chemicals with the potential to reduce P losses from agricultural grassland arising from the land application of dairy cattle slurry. It also aims to identify optimal application rates ... -
Impact of chemical amendment of dairy cattle slurry on phosphorus, suspended sediment and metal loss to runoff from a grassland soil.
(Science of the Total Environment, 2011-11-01)Emerging remediation technologies such as chemical amendment of dairy cattle slurry have the potential to reduce phosphorus (P) solubility and consequently reduce P losses arising from land application of dairy cattle ... -
The performance of constructed wetlands treating primary, secondary and dairy soiled water in Ireland (a review).
(Journal of Environmental Management, 2011-11-01)In Ireland, no database detailing the design, influent loading rates or performance of constructed wetlands (CWs) exists. On account of this, they are designed without any protocol based on empirical data. The aim of ... -
Evaluation of amendments to control phosphorus losses in runoff from dairy soiled water.
(Springer, 2011-12-01)Amendments with the potential to reduce phosphorus (P) losses from agricultural grassland arising from the land application of dairy-soiled water (DSW) were investigated. Optimal application rates were studied, and associated ... -
Determination of flushing characteristics of the Irish Sea: A spatial approach
(Elsevier ScienceDirect, 2011-12-08)The Authors devised a novel generic approach to assessing the flushing of the Irish Sea through the determination of spatially distributed residence times and the development of flushing homogeneity curves. Results indicate ... -
Economic analysis of pig manure treatment options in Ireland.
(2012)An economic analysis was performed on treatment options for pig manure in Ireland. Costs were based on a 500 sow integrated pig farm producing 10,500 m3 of manure per year at 4.8 % dry matter. The anaerobic digestion of ... -
The creation of a living laboratory for structural engineering at the National University of Ireland, Galway
(2012)The recently completed New Engineering Building (NEB) at the National University of Ireland, Galway (NUIG) is a new state of the art academic facility on the university's north campus. The building unites all five ... -
Effect of sawdust addition on composting of separated raw and anaerobically digested pig manure
(Elsevier, 2012)Manures need the addition of carbon-rich bulking agents to conserve N during composting, which increases the cost of the composting process. The recommended proportion of manure/sawdust, based on a carbon (C):nitrogen (N) ... -
Engineering in Communities Learning by Doing
(2012)Purpose The purpose of this paper is to focus on a number of initiatives in civil engineering undergraduate programmes at the National University of Ireland, Galway (NUIG) that allow students to complete engineering ... -
Numerical simulation of linear water waves and wave-structure interaction
(2012)One of the main stages in the design of wave energy converters (WEC's) is the numerical modelling of a given converter. In this paper, the numerical simulation of both linear deep water waves and linear waves for the finite ... -
Improving the Delivery of a Construction Management Study-Abroad Course in Ireland through Student Feedback
(2012)International study abroad offers limitless opportunities for students to learn outside of the traditional university setting. By living and learning in a foreign country, the student's exposure to a different culture can ... -
Nutrient dynamics in a peatland forest riparian buffer zone and implications for the establishment of planted saplings
(2012)Forestry on peatland throughout the world is now focused on minimising destructive effects to the surrounding environment, especially during harvesting. These effects may be mitigated through the use of well-developed ... -
An integrated approach to trophic assessment of coastal waters incorporating measurement, modelling and water quality classification
(2012)Various protocols have been developed for trophic assessment of coastal waters but most incorporate single value compliance criteria for water quality parameters which, in reality, exhibit significant spatial variation. ...
