This research aims to design a model for managing urban floods in Tehran. For this purpose, DSPIR model and Delphi panel (consensus of 18 experts) were used. In order to achieve effective criteria and indices, a researcher-made questionnaire was used, and to determine the validity and reliability of the questionnaire, Cronbach's alpha method was used by SPSS, Version 21 software. Fuzzy AHP (Analytic Hierarchy Process) method was used to determine the weights of criteria as well as classes of each criterion, and PLS (Partial Least Squares) method to fit the model. The results indicated that the model in connection with flood driving force in Tehran comprises 5 components and 16 dimensions. Evaluation of goodness for model fit shows that GFI is equal to 0.954, which is within the acceptable range. RMR is equal to 0.011, which is within the acceptable range. TLI, CFI and IFI are 0.931, 0.987 and 0.986, respectively, all of which are within acceptable ranges. CMIN/DF is equal to 4.255, and RMSEA is equal to 0.065, therefore, they are within acceptable ranges. In general, the results of model analysis and evaluation showed that the model has the accuracy needed to simulate urban runoff and this model can be used for urban flood management plans and design of urban flood drainage network in the studied area.
