  • Emission standards versus immission standards for assessing the impact of urban drainage on ephemeral receiving water bodies

    In the past, emission standard indicators have been adopted by environmental regulation authorities in order to preserve the quality of a receiving water body. Such indicators are based on the frequency or magnitude of a polluted discharge that may be continuous or intermittent. In order to properly maintain the quality of receiving waters, the Water Framework Directive, following the basic ideas ...

  • IFDM modelling for optimal siting of air quality monitoring stations around five oil refineries

    An IFDM modelling study has been conducted to determine the optimal siting of air quality monitoring stations around five oil refineries. The purpose of this immission monitoring network is specified in environmental legislation. The most appropriate output parameter of the IFDM model for this study is the 98th percentile of the moving 24 h averages, P98,m24h. Modelling for the optimal siting of ...

  • The 1998 IFDM evaluation with the model validation kit

    A modification of the Immission Frequency Distribution Model (IDFM) can reproduce the Kincaid and Indianapolis arc-wise maximum ground-level concentrations (GLCs) and crosswind integrated concentrations (CWICs) fairly well. But we doubt whether these modifications are really an improvement of the description of the natural ambient atmospheric dispersion process, rather than merely fitting a ...

  • A decision support system for air quality management combining GIS and optimisation techniques

    This paper describes a multi-tiered approach to the design of plans and policies for urban environmental management, in particular air quality, as related to the energy and transportation sectors. The approach is based on the iterative combination of sectoral and global optimisation models, including a discrete multi-criteria approach, and spatially distributed air quality models. The approach ...

  • An integrated approach for urban water quality assessment

    This paper introduces an integrated approach for the assessment of receiving water quality and the relative contribution of the urban drainage system to perceived receiving water quality problems. The approach combines mass balances with relatively simple receiving water impact models. The research project has learned that the urban drainage system is only one of the determining factors with ...

  • Comparing the impact of a road tunnel vs. a road viaduct by means of an integrated exposure assessment

    Using the MOBILEE methodology, we performed a detailed air quality assessment for three scenarios for the ring road around Antwerp, a major city in Belgium, using PM10 and NOx emission inventories for 2003 (reference) and 2015 (projected future situation), followed by an assessment of the exposure of the ...

  • Universal system for forecasting changes in PM10 and PM2.5 particulate matter air pollution concentration

    We present a system for forecasting the changes in PM 10 and PM 2.5 particulate matter air pollution concentration. The system is based on immissions data from automatic measurement stations of the Voivodship (Regional) Inspectorate for Environmental Protection in Warsaw (Poland) and a numerical forecast of meteorological parameters from the Interdisciplinary Centre for ...

  • Chemical reactions at street scale using a Lagrangian particle dispersion model

    In the context of the FEDER AIRCITY project, Paris City is modelled with a 3 m resolution with the purpose of computing pollutant concentration relevant for human exposition. This project involves AIRPARIF (Ile-de-France Air Quality Monitoring Network), for emission and immission data, CEA (French Atomic and Alternative Energy Agency) for HPC availability, National Geographic Institute (IGN) for ...

  • A dataset for the validation of flow and dispersion models at an urban intersection

    Dispersion modelling concerning air pollution caused by road traffic is reduced to a two-dimensional problem within street canyons. However, significant pollution loads are also to be expected at intersections. In this case, three-dimensional flow and dispersion structures have to be considered. For the validation of models claimed to be applicable to intersections, measurements of meteorological ...

  • Neptune Project Deliverable D1.2

    Several EU member states have yet to satisfy the stringent nutrient removal requirement of the Urban Waste Water Directive (1991) for sensitive areas. An environmental engineer working in the field of wastewater treatment is faced with increasing demands on the treatment efficiency. With the new European Water Framework Directive (EWFD, 2000/60/CE) there is a shift in paradigm from emission-based ...
