TY - GEN T1 - Assessment of uncertainties in the modelling of CSOs AU - Garc\303\255a-Salas, J. C. AU - Chocat, B.

Equations that are used by these models to represent the hydraulics of sewer systems are well known as well as their performance. Thus the assessment of the performance needs to suppose that the user is an expert who is able to describe each facility in the most accurate way according to the model. In Western Europe, important parts of sewer systems are old and combined structures. Such structures very often include very complicated special structures, especially within CSO facilities. Experience shows that the performance limits of the models do not rely on the accuracy of the equations, but on the ability of the modeller to properly describe these special structures. The objective of this research is to assess the part of errors and uncertainties which originates from modellers\342\200\231 inconsistencies in the description of special structure. Even if the results are obtained with specific software (CANOE), results can easily be generalised to other models, since the equations used (Barr\303\251 de Saint Venant, ...) are almost the same.
