As a part of attempt for phosphorus (P) recovery from P-saturated alum sludge, which was used as a low-cost P-adsorbent in treatment reed bed for wastewater treatment, decolouration of H2SO4 leachate obtained from previous ...
Implementation of appropriate management strategies to mitigate diffuse phosphorus (P) pollution at the catchment scale is vitally important for the sustainable development of water resources in Ireland. An important element ...
A thermal response test (TRT) is a controlled insitu test during which a known quantity of heat energy is injected into a closed loop heat-exchanger pipe while the heat dissipation rate into the surrounding ground is ...
Simple limit equilibrium analyses can be performed to determine the Factor of Safety (FOS) against slope failure of unsaturated soil slopes. However, many of the input parameters needed for these analyses are highly variable, ...
Since 1975, flood estimation in Ireland has generally
followed methods as outlined in the Flood Studies Report
(Natural Environment Research Council, 1975). An update
of this for conditions in the Republic of Ireland ...
This paper describes the design of the curriculum for a Master of Engineering programme in civil engineering at University College Dublin. The revised programme was established to meet the requirements of the Bologna process ...
Highway structures such as bridges are subject to continuous degradation primarily due to ageing and environmental factors. A rational transport policy requires the monitoring of this transport infrastructure to provide ...
The development of accurate codes for the design of bridges and the evaluation of
existing structures requires adequate assessment of heavy traffic loading and also the dynamic interaction that may occur as this traffic ...
The ultimate goal of the project reported herein was to determine whether or not a readily quantifiable threshold data density could be established to accurately predict subsurface lithology. A study area in Dublin Ireland ...
Grid-oriented, physically based catchment models calculate fields of various hydrological variables relevant to phosphorous detachment and transport. These include (i) for surface transport: overland flow depth and flow ...

Ireland has one of the highest energy dependencies in Europe and as such must adapt quickly to increase renewable energy exploitation levels in order to secure its energy future. A mix of renewable energy technology types ...
This paper describes the development of a model instrumented open-ended (pipe) pile. The importance of model geometry and separating the shaft, annular and plug load, and horizontal effective stresses is discussed. A ...
Asphalt is a complex, heterogeneous material that is composed of differently sized aggregates, binder and air voids: in other words, it is a particulate reinforced composite. The focus of the present work is to investigate ...
This paper discusses the design and development of a new direct simple shear (DSS)
apparatus for testing peat soils. The apparatus has been designed to test peat at low
effective stresses, representative of its in-situ ...
The paper considers the influence of the surface profile on the dynamic amplification of a simply supported bridge when subject to a quarter car vehicle model. The effect of the profile irregularities on the bridge dynamic ...
This paper describes (in a summarised manner) a research attempt to integrate the dewatered alum sludge, a residual by-product of drinking water treatment process, into a constructed wetland (CW) system for the purpose of ...
The number of commercial vehicles using Irish roads has increased considerably in recent years, leading to higher demands being placed on pavement materials and increased use of polymer modified bitumens. This has also ...
Binders manufactured using a blend of gypsum, ground granulated blast furnace slag and Portland cements are technically viable and possess considerable environmental and economic advantages when compared to binders ...
