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 ...
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 ...
Methodology for the location of a subsurface permeable reactive barrier for the remediation of point source pollution on an Irish farm
(Teagasc, 2008-09)
Nutrient loss from agricultural sources to water continues to be a national challenge. Diffuse pollution from agricultural sources is considered to be the primary cause of slight-to-moderate water pollution in Ireland, but ...
Surface clogging in an intermittent stratified sand filter.
(Soil Science Society of America Journal, 2004-06-01)
Accumulation of biomass and deposition of suspended solids at the surface of a sand filter can lead to clogging of the filter media. A laboratory intermittent sand filter column, which included 3 sand strata, was operated ...
Application of optimization methods to the design of high performance composite pipelines
(Elsevier, 2003-04-23)
This paper describes a contribution to the research carried out by a consortium under the BRITE/EURAM programme of the EC on the application of optimisation techniques to problems of engineering design using composite ...
Stress changes associated with driving pile groups in clayey silt
(National University of Ireland Galway, 2003)
Measurements obtained from lateral total stress sensors located on the centre pile of a
small driven pile group and pneumatic piezometers installed in the vicinity of the group are used to
assess the disturbance associated ...
Experimental investigation of the response of a driven pile in soft silt
(National University of Ireland Galway, 2004-12-01)
The paper describes the results of field tests carried out using highly instrumented piles at a
very soft estuarine clayey silt deposit at Kinnegar, Belfast. The site has been used for a number of years as a
geotechnical ...
Observed installation effects of vibro-replacement stone columns in soft clay
(National University of Ireland Galway, 2008-09-03)
The installation of vibro replacement stone columns in any soil causes significant changes to
the stress regime around each probe location. In soft clays, the principal effects are caused by a cavity expansion mechanism ...
Measured and predicted t-z curves for a driven pile in lightly overconsolidated silt
(National University of Ireland Galway, 2008-04-03)
Data from a static compression load test on a single driven pile in a lightly overconsolidated silt
are presented in this paper. The pile was equipped with vibrating wire strain gauges along its length enabling
its load ...
Is geotechnical education meeting industry demands? The Irish position
(National University of Ireland Galway, 2008-06-02)
This paper presents the results of a survey carried out in late 2007 to gauge how geoengineering education is perceived to meet the demands of Irish industry. The survey was internet-based and
the responses provide some ...
