A REVIEW OF MODEL DEVELOPMENT BASED ON SEWER SEDIMENTS RESEARCH IN THE UK

A major programme of research into the nature, behaviour and occurrenc e of sediment deposits associated with sewer systems has been carried out in the UK since 1988. This research has been co-ordinated by the U K water industry's Urban Pollution Management Programme. The main driv ing force behind this research has been the need to collect fundamenta l data to support the development of sewer flow quality simulation mod els. Research results have significantly enhanced knowledge pertaining to sewer sediments and this has proved to be crucial to the developme nt of reliable modelling tools to predict the quality of sewer system discharges. Particular advances have been made in the ability to under stand and represent the effects of sewer sediment rheology and the att achment of pollutants to sediments. Many performance limitations of cu rrent models, such as MOSQITO and MOUSE TRAP, can be related tb the mo delling of sewer sediments. User requirements for the next generation of models will only be met if sewer sediments research results are ful ly utilised and further research can be tailored to meet end user driv en modelling requirements. This paper reviews the results and applicat ions of sewer sediments research in the UK and identifies additional r esearch required to support further model development. Copyright (C) 1 996 WRc plc.
