Abstract

The main issue of this paper is to analyze the water depth uncertainty in manholes of a main pipeline of urban surface drainage system. Also sensitivity analysis for subcatchment peak flood discharge is investigated. As a case study, a basin located in the center of historical city, Shiraz, in southwest of Iran is considered. SWMM model is used to simulate rainfall-runoff process and flood routing in conduits. Monte-Carlo simulation and L.H.S method is used for uncertainty analysis. The results showed that water depth coefficient of variation in manholes varies from 12% to 66% and its probability distribution has a considerable positive skewness. Subbasin areas and precipitation parameters leave the most important effect on peak flood discharge and its uncertainty.
