URBAN POLLUTION MODELLING:
IMPROVED CO-ORDINATION OF QUALITY MODELLING
Having an effective and comprehensive modelling capability is an essential precursor to application of the UPM planning methodology. The co-ordinated collection of data and the construction of widely applicable models will minimise costs and maximise efficiency for all the planning procedures which rely upon the use of simulation models. This report offers guidelines for the co-ordinated collection of data for use with these simulation models.
The overall aim of the Urban Pollution Modelling project is to enhance the existing UPM simulation modelling capabilities. This phase of the project is to review the specifications of the major modelling applications to ensure compatibility of modelling procedures.
Simulation models provide the foundation for many activities throughout the water industry (DAP's, AMP2, catchment plans, as well as specific scheme designs). The detailed modelling requirements differ to some extent for each type of application. Data collection and model construction/validation for all applications should be planned and undertaken in a co-ordinated fashion for maximum efficiency.
Review of the modelling procedures highlights the need for good verification data for all of the modelling packages. There is a need for the co-ordinated collection of quality data. It also highlights the need for a full time Site Engineer when undertaking quality surveys. A precursor to any data collection exercise is detailed planning. Effective communication between all parties involved in the UPM planning procedure should be established at the commencement of the study.
Quality data should be complete for the whole storm for all components modelled. Improved liaison with the Meteorological Office is advised such that an effective storm warning system may be developed. Effective communication should be established with laboratories undertaking sample analysis.
It is recommended that whenever the UPM planning procedure is applied, detailed planning of each phase of the project is undertaken, involving all of the relevant parties. Data collection for effluent surveys should be concentrated on major overflows wi thin the sewerage system and major impact locations within the river.
It is also recommended when applying the UPM procedure, these guidelines are followed.
This report provides an overview of the modelling procedures developed during the UPM programme, from a review of reports and the detailed user guides. The background to the UPM programme is given in Section 1. Section 2 lists and describes the modelling tools that have been developed during the UPM programme. Section 3 describes the data requirements for the hydraulic modules of the simulation models and gives guidelines for the co-ordination of data collection and model construction. Section 4 describes the data requirements for the water quality modules of the simulation models and gives guidelines for the co-ordination of data collection. Conclusions and recommendations are given in Section 5.
