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 ... -
The impact of alternating drainage and inundation cycles on geochemistry and microbiology of intact peat cores
(Elsevier, 2022-11-02)The rewetting of degraded peatlands has been adopted as a method to address climate change. Concerns have been raised about the effects of peat inundation and drying cycles, in more extreme climate events, on the potential ... -
The Impact of Biochar Addition on Nutrient Leaching and Soil Properties from Tillage Soil Amended with Pig Manure
(Springer, 2014-02)The application of pig manure to a tillage soil can result in pollution of surface and groundwater bodies. Countries in the European Union are required to comply with the Water Framework Directive, which states that all ... -
Impact of biochar addition to soil on greenhouse gas emissions following pig manure application
(2013)The application of biochar produced from wood and crop residues, such as sawdust, straw, sugar bagasse and rice hulls, to highly weathered soils under tropical conditions has been shown to influence soil greenhouse gas ... -
The impact of chemical amendment of dairy cattle slurry before land application on soil phosphorus dynamics
(Taylor and Francis, 2014-08-22)Application of dairy cattle slurry to agricultural soils, particularly those with high phosphorus (P) status or vulnerability to runoff, can increase P loss to waterbodies, which may accelerate eutrophication. While the ... -
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 ... -
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 ... -
Impact of chemically amended pig slurry on greenhouse gas emissions, soil properties and leachate.
(2013)The effectiveness of chemical amendment of pig slurry to ameliorate phosphorus (P) losses in runoff is well studied, but research mainly has concentrated only on the runoff pathway. The aims of this study were to investigate ... -
Impact of historical legacy pesticides on achieving legislative goals in Europe
(Elsevier, 2023-02-26)Pesticides are widely used in agriculture to optimise food production. However, the movement of pesticides into water bodies negatively impacts aquatic environments. The European Union (EU) aims to make food systems fair, ... -
Impact of P inputs on source-sink P dynamics of sediment along an agricultural ditch network
(Elsevier, 2019-12-19)Phosphorus (P) loss from intensive dairy farms is a pressure on water quality in agricultural catchments. At farm scale, P sources can enter in-field drains and open ditches, resulting in transfer along ditch networks and ... -
