Real-Time Prediction System Of Bathing Water Quality At Bray, Co. Wicklow, Ireland, Zeinab Bedri, John O'Sullivan, Aisling Corkery, Louise Deering, Katalin Demeter, Wim Meijer, Gregory O'Hare, Bartholomew Masterson

Conference papers

Variations in water quality at recreational bathing beaches can have significant impacts with respect to compliance with related water quality standards, such as Directive 76/160/EEC. The “Blue Flag” award which bases its water quality standards upon the guideline E.coli levels of Directive 76/160/EEC, has become the measure of recreational value of bathing areas. Loss of such designations can have significant impacts with respect to local tourist economies. A revised Bathing Water Directive (Directive 2006/7/EC) came into force in 2006 and will supersede the existing 1976 Directive with effect from December 2014.

The revised Directive gives stronger focus on the protection …

Developing Archetypes For Domestic Dwellings:An Irish Case Study, Albert Famuyibo, Aidan Duffy, Paul Strachan

Articles

Stock modelling, based on representative archetypes, is a promising tool for exploring areas for resource and emission reductions in the residential sector. The use of archetypes developed using detailed statistical analysis (multi-linear regression analysis, clustering and descriptive statistics) rather than traditional qualitative techniques allows a more accurate representation of the overall building stock variability in terms of geometric form, constructional materials and operation. This paper presents a methodology for the development of archetypes based on information from literature and a sample of detailed energy-related housing data. The methodology involves a literature review of studies to identify the most important variables …

An Environmental Consequence For Dublin Bay Of A Shift From Hydro-Carbon To Other Energy Production Methods, Zeinab Bedri, John O'Sullivan, Michael Bruen

Conference papers

The Liffey Estuary and Dublin Bay, Ireland are of a great recreational and conservational value. Until recently, the Electricity Supply Board (ESB) plant at Poolbeg, Dublin, abstracted dilution water from the estuary for cooling purposes and subsequently discharged this water back to the estuary at temperatures that were sometimes 7-9oC above ambient values. Prior to its discharge to the estuary, the ESB cooling water was mixed with the sewage effluent from Ringsend Treatment Works, creating a warmer and less-saline pollutant plume that remained buoyant on the water surface, adversely effecting water quality. The ESB plant has since closed as part …

Lynches Lane Reed & Willow Bed Facility Final Report South Dubin County Council, Liam Mccarton, Sean O'Hogain, Don Mcdonald, Anna Reid

Reports

This final report will present results from a two year study to monitor the performance of a hybrid reed willow bed facility at Lynches Lane, in the administrative area of South Dublin County Council (SDCC). Design specifications for the facility are presented. Monitoring results for a two year period including influent and effluent parameters, rainfall, potential evapotranspiration, and soil classification are also presented and discussed. During the two year monitoring period the system achieved a zero discharge. This report will discuss the potential application of similar systems within South Dublin County Council administrative area. This is in the context of …

An Improved Flood Forecasting Model Of The Blue Nile River In Sudan, Gamal Abdo, Ahmed Nasr

Articles

Reliable flood predictions with a reasonable lead time in the Blue Nile River in Sudan are vitally important to avoid catastrophic damages due to flooding of this river and the main River Nile. A HEC-RAS model was initially applied to the Blue Nile by representing the river as a single reach. The resulting original model was subsequently improved by including the two tributaries of the river, Rahad and Dindir, and also the two existing reservoirs, Rosaries and Sinnar, to the model. The original and the improved models were calibrated using 1988 flood data for the period from June to September …
