Abstract:

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 effectivecriteria and indices, a researcher-made questionnaire was used, and to determine the validity andreliability 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 aswell as classes of each criterion, and PLS (Partial Least Squares) method to fit the model. Theresults indicated that the model in connection with flood driving force in Tehran comprises 5components and 16 dimensions. Evaluation of goodness for model fit shows that GFI is equal to0.954, which is within the acceptable range. RMR is equal to 0.011, which is within the acceptablerange. TLI, CFI and IFI are 0.931, 0.987 and 0.986, respectively, all of which are within acceptableranges. CMIN/DF is equal to 4.255, and RMSEA is equal to 0.065, therefore, they are withinacceptable ranges. In general, the results of model analysis and evaluation showed that the modelhas the accuracy needed to simulate urban runoff and this model can be used for urban floodmanagement plans and design of urban flood drainage network in the studied area.
