Dynamics Of Suspended Sediment Flux On The Rivers Bandon And Owenabue, Ireland, S. T. Harrington, Joseph R. Harrington

Monitoring, analysis and modelling of suspended sediment transport in riverine systems has received much attention in recent decades. Quantitive analysis techniques have been applied to allow river basin managers to assess suspended sediment transport and its importance in transporting a range of pollutants including excess metals and nutrients, which negatively impact on aquatic systems. In this paper, an analysis of the suspended sediment fl ux (SSF) dynamics is presented for the small and medium sized catchments of the River Owenabue and the River Bandon, respectively. The results contribute to the fi lling of a research gap in an Irish context …

Partial replacement of high clinker content cements by Ground Granulated Blastfurnace Slag (GGBS) can reduce the carbon footprint of concrete, with consequent benefits in respect of sustainable construction. Furthermore a state-of-the-art report indicated that use of GGBS as a binder replacement may increase the fire resistance of concrete. If so this could lead to thinner sections in fire compartment elements, especially non-loadbearing walls, leading to further gains in respect of sustainable development. Concrete is considered an effective material in protecting against the detrimental effects of fire in structures. However, exposure to high temperatures can degrade concrete performance. Fire resistance performance …
Dissolved And Particulate Nutrient Transport Dynamics Of A Small Irish Catchment: The River Owenabue, S. T. Harrington, Joseph R. Harrington

The objective of this research was to investigate the relationship between water and sediment discharge on the transport of nutrients: nitrogen and phosphorus. Water discharge, suspended sediment concentration and dissolved and particulate forms of nitrogen and phosphorus were monitored on the 105 km2 River Owenabue catchment in Ireland. Water discharge was found to have an influence on both particulate and dissolved nutrient transport, but more so for particulate nutrients. The particulate portion of N and P in collected samples was found to be 24 and 39 %, respectively. Increased particulate nitrogen concentrations were found at the onset of high discharge …
Stock Aggregation Model And Virtual Archetype For Large Scale Retrofit Modelling Of Local Authority Housing In Ireland, James Pittam, Paul D. O’Sullivan, Garrett O’Sullivan

Developing representative archetypes using a bottom up approach for stock modelling is an excellent tool for evaluating the overall performance of the building stock; however it requires detailed analysis of the various building types. Currently there is no detailed housing data base for Local Authority housing in Cork City, Ireland that catalogues the housing stocks geometric properties and thermal characteristics for each typology. This study details a methodology to catalogue the LAH stock and build a detailed housing data base. The GIS web based mapping application Google Street View is used to identify 20 house typologies across 36 LAH developments; …
