A mathematical model can be a fast and low-cost tool for estimating its emission. This study investigates two approaches to modeling H2S gas transfer at a waterfall in a discharge manhole. The first approach is based on an adaptation of oxygen models for H2S emission at a waterfall and the second consists of a new model. An experimental set-up and a statistical data analysis allowed the main factors affecting H2S emission to be studied. A new model of the emission kinetics was developed using linear regression and taking into account H2S liquid concentration, waterfall height and fluid velocity at the outlet pipe of a rising main. Its prediction interval was estimated by the residual standard deviation (15.6%) up to a rate of 2.3 g H2S\u00b7h\u22121. Finally, data coming from four sampling campaigns on sewer networks were used to perform simulations and compare predictions of all developed models.<\/jats:p>","DOI":"10.2166\/wst.2017.428","type":"journal-article","created":{"date-parts":[[2017,8,5]],"date-time":"2017-08-05T00:20:13Z","timestamp":1501892413000},"page":"2753-2763","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":11,"title":["Emission of hydrogen sulfide (H2S) at a waterfall in a sewer: study of main factors affecting H2S emission and modeling approaches"],"prefix":"10.2166","volume":"76","author":[{"given":"Daniel","family":"Jung","sequence":"first","affiliation":[{"name":"Veolia Environnement Recherche & Innovation, Chemin de la Digue \u2013 BP76, 78603 Maisons-Laffitte, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laetitia","family":"Hatrait","sequence":"first","affiliation":[{"name":"Veolia Environnement Recherche & Innovation, Chemin de la Digue \u2013 BP76, 78603 Maisons-Laffitte, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julien","family":"Gouello","sequence":"first","affiliation":[{"name":"Veolia Environnement Recherche & Innovation, Chemin de la Digue \u2013 BP76, 78603 Maisons-Laffitte, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arnaud","family":"Ponthieux","sequence":"first","affiliation":[{"name":"Veolia Environnement Recherche & Innovation, Chemin de la Digue \u2013 BP76, 78603 Maisons-Laffitte, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vincent","family":"Parez","sequence":"first","affiliation":[{"name":"Veolia Eau, Direction Technique, Immeuble Battista B, 1 rue G.
