Sciomyzidae (Diptera) assemblages in constructed and natural wetlands: implications for constructed wetland design.
(Springer, 2023-12-08)Wetlands constructed primarily for the treatment of wastewaters have been shown to have a role in enhancing biodiversity. However, while most biodiversity studies of constructed wetlands focus on the larger, more iconic ... -
Seasonal patterns of metals and nutrients in Phragmites australis (Cav.) Trin. ex Steudel in a constructed wetland in the west of Ireland.
(Elsevier, 2017-07-23)An understanding of the seasonal variation in the standing stock of metals and nutrients in emergent vegetation of constructed wetlands (CWs), as well as the amounts present in aboveground (AG) and belowground (BG) biomass, ... -
Shaft resistance of driven cast-in-situ piles in sand
(NRC Research Press, 2015-06-25)Driven cast-in-situ (DCIS) piles are classified as a large displacement pile, despite sharing certain aspects of their construction with replacement pile types. However, there are relatively few case histories of load tests ... -
The short-term effects of management changes on watertable position and nutrients in shallow groundwater in a harvested peatland forest
(Elsevier, 2014-09-01)Management changes such as drainage, fertilisation, afforestation and harvesting (clearfelling) of forested peatlands influence watertable (WT) position and groundwater concentrations of nutrients. This study investigated ... -
Simultaneous adsorption and biodegradation of trichloroethylene occurs in a biochar packed column treating contaminated landfill leachate
(Elsevier, 2021-08-14)Trichloroethylene (TCE) is a human carcinogen that is commonly found in landfill leachate as a result of anthropogenic activities. Contaminated leachate plumes may be intercepted prior to reaching groundwater and treated ... -
Some geotechnical characteristics of soft soil deposits along the Terryland River Valley, Galway
(2016)The ground conditions in the Terryland River Valley area present considerable site development challenges to geotechnical engineers. The soft soil formation consists of peat overlying very soft, highly compressible calcareous ... -
Spatial and temporal variations of nutrient loads in overland flow and subsurface drainage on a marginal land site in South-East Ireland
(2013)In Ireland, Food Harvest 2020 focuses on increasing productivity whilst enhancing environmental sustainability of agricultural land. On under-utilised or marginal land, drainage systems may be installed to expand agricultural ... -
Split phosphorus fertiliser applications as a strategy to reduce incidental phosphorus losses in surface runoff
(Elsevier, 2019-04-24)Organic soils have low sorption capacities for phosphorus (P), and may pose a risk of P loss to water if P applications to these soils coincide with runoff events. Little is known about the magnitude of exports of P in ... -
Stabilisation for peat improvement: Extent of carbonation and environmental implications
(Elsevier, 2020-06-13)The construction industry is a large contributor to global greenhouse gas emissions. In recent years, the industry has begun to consider sustainability alongside technical merit, cost and programme when analysing construction ... -
Stabilisation of a dredged marine sediment: geotechnical and contaminant leaching properties
(Civil Engineering Research in Ireland CERI, 2018-08-29)In this paper, contaminated sediment dredged from a commercial harbour in Ireland was stabilized using Ordinary Portland cement (OPC) alone and in combination with Ground Granulated Blast Furnace Slag (GGBS). The engineering ... -
Statistical grain size effects in fretting crack initiation
(Elsevier, 2016-09-20)A crystal plasticity computational framework is developed and validated to investigate the microstructure sensitivity of crack initiation in fretting. Randomly distributed microstructure geometries are incorporated into a ... -
A statistically based fault detection and diagnosis approach for non-residential building water distribution systems
(Elsevier, 2020-11-01)Large non-residential buildings can contain complex and often inefficient water distribution systems. As requirements for water increase due to water scarcity and industrialization, it has become increasingly important to ... -
Stone column effectiveness in soils with creep: a numerical study
(Taylor & Francis, 2016-03-16)While it is well established that vibro stone columns reduce primary settlement and improve bearing capacity, their effect on creep compression has largely been overlooked to date. However, with increasing pressure to ... -
Stone column settlement performance in structured anisotropic clays: the influence of creep
(Elsevier, 2016-07-15)The recently developed elasto-viscoplastic Creep-SCLAY1S model has been used in conjunction with PLAXIS 2D to investigate the effectiveness of vibro-replacement in a creep-prone clay. The Creep-SCLAY1S model accounts for ... -
Storms and surges in Irish coastal waters
(Elsevier ScienceDirect, 2010-04-29)Mechanisms of storm surge formation and severity on the north European continental shelf and, in particular, in the Irish coastal waters are examined in this paper. A numerical surge model was developed and used in combination ... -
Strength and durability performance of stabilised soil block masonry units
(IABSE, 2012)This paper presents the findings from laboratory strength and durability tests on stabilised soil blocks (SSBs). SSBs are masonry units formed by compressing a mixture of soil and a stabiliser such as cement and water in ... -
Strength grading of timber in the UK and Ireland in 2021
(Taylor & Francis, 2022-03-19)This paper summarises the state of the art for strength grading of construction timber grown in the United Kingdom and the Republic of Ireland. It includes the latest approvals based on recent research on spruce, larch and ... -
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 ... -
The structural behaviour of compressed wood manufactured using fast-grown sitka spruce
(National University of Ireland Galway, 2021-08-09)An investigation was carried out to examine the potential to manufacture a compressed wood product from fast-grown Sitka spruce, using a process of thermo-mechanical compression to increase its strength and stiffness. The ...
