Forecasting sanitary risks for open-water swimming in urban areas

Résumé

Urban water bodies are increasingly used for recreational activities, including swimming. The practice of open water swim requires a good water quality, complying with sanitary regulations based on the concentration of faecal indicator bacteria. To forecast a possible sanitary risk, a monitoring station can be implemented upstream of the bathing area. Then the transfer time of the microbiological contaminant must be accurately modelled in order to derive the contamination level in the bathing area. A hydrodynamic model is a useful tool for achieving this goal. In La Villette basin (Paris, France), as part of Paris-Plage programme, a bathing area has been implemented since summer 2017. We present in this paper results of a 3D hydrodynamic model of La Villette basin, the transport of E.coli towards the swimming area and the advantages of this modelling approach.
