Uncertainty analysis in sewer systems performance evaluation

2005

In recent years, in order to analyse complex urban drainage systems and to identify the most effective measures for improving their efficiency, many parameters, or indicators, have been defined and many methodologies have been proposed in order to quantify sewer systems performance in the most objective and general way. However, some uncertainty arises in these methodologies due to choices which the user has to take in applying the procedure. Thus, performance analysis results are affected by operator experience and they are mainly useful for comparison between different scenarios applied to the same system. In the present paper, a statistical analysis of sewer systems performance has been …
