Behaviour of tubular steel members under cyclic axial loading
(2006)
This paper examines the cyclic performance of axially-loaded tubular members used as bracing elements to provide lateral seismic resistance in steel framed structures. An experimental study into the response of members ...
A review of field performance of stone columns on soft soils
(2009-12)
The behaviour of stone columns has yet to be captured fully by analytical and numerical techniques, and predicting column behaviour in soft cohesive soils brings specific challenges. This paper provides a comprehensive ...
A nested hydrodynamic model incorporating flooding and drying
(2009)
A one-way nested version of the hydrobiological model DIVAST (Depth Integrated Velocity and Solute Transport) is introduced. The nested model allows flooding and drying of intertidal areas, a process often present in areas ...
Nutrient dynamics in Cork Harbour
(2005)
Estuaries are commonly characterised by high productivity due to frequent if not continuous inputs of nutrients from domestic and industrial discharge effluents and from freshwater and marine sources. These forms of nutrient ...
A nested version of the combined hydrodynamic and water quality model, DIVAST
(2007)
The present research deals with the development of a one-way nested version of the combined hydrodynamic and water quality model DIVAST (Depth Integrated Velocity and Solute Transport). Initial research has concentrated ...
Modelling nutrients and chlorophyll-a dynamics in an Irish brackish waterbody
(Elsevier, 2004)
This paper presents aspects of a research investigation into nutrient fluxes into and out of an important Irish estuary, Wexford Harbour, located in the southeast of Ireland. Details of the methodology applied, the data ...
Denitrification of a nitrate-rich wastewater using various wood-based media materials
(2006)
This laboratory study examined the use of various wood materials as a carbon source in horizontal flow filters to denitrify nitrate-nitrogen (NO3-N) from a synthetic wastewater. The filter materials were: sawdust ( Pinus ...
Modelling nutrient and chlorophyll_a dynamics in an Irish brackish waterbody
(Elsevier, 2004-01)
This paper presents aspects of a research investigation into nutrient fluxes into and out of an important Irish estuary, Wexford Harbour, located in the southeast of Ireland. Details of the methodology applied, the data ...
Performance of a stratified sand filter in removal of chemical oxygen demand, total suspended solids and ammonia nitrogen from high-strength wastewaters.
(Journal of Environmental Management, 2007-06-01)
A stratified sand filter column, operated in recirculation mode and treating synthetic effluent resembling high strength dairy wastewaters was studied over a 342 day duration. The aim of this paper was to examine the ...
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 ...
