Acoustic profilers and urban pollutant fluxes / Erwan Le Barbu in European journal of environmental and civil engineering, Vol. 14 N° 5 (Mai 2010) 

Public ISBD [article]  in European journal of environmental and civil engineering > Vol. 14 N° 5 (Mai 2010) . - pp. 637-651 Titre : Acoustic profilers and urban pollutant fluxes Type de document : texte imprimé Auteurs : Erwan Le Barbu, Auteur ; Frederique Larrarte, Auteur Année de publication : 2011 Article en page(s) : pp. 637-651 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Acoustic  profiler  Suspended  solids  Velocity  Sewer  system Index. décimale : 624 Constructions du génie civil et du bâtiment. Infrastructures. Ouvrages en terres. Fondations. Tunnels. Ponts et charpentes Résumé : A prudent management of networks, along with the minimisation of pollution discharged into receiving waters, requires an accurate knowledge of flow rates and pollutant loads conveyed in sewers. Conventional methods are based on well-known techniques, including acoustic devices and the sampling and analysis of total suspended solids. Although such methods yield satisfactory results for a typical gauging campaign, sensor implementation proves to be rather difficult. This study is intended to test the capabilities of acoustic Doppler profilers (ADP); the paper will present a PC-ADP profiler and the set of accompanying experiments. Initial results demonstrate great improvement offered by profiling techniques, in terms of both simultaneity and time savings.
