摘要

This study aimed to develop the technique for order of preference by similarity to ideal solution multicriteria decision model for selecting the appropriate sustainable urban drainage systems (SUDS) for cities in the Brazilian center-south region. The methodology was selected to prioritize the options presented, facilitating the combination of urban drainage alternatives. This differential of the multicriteria decision model is the social subcriteria used, along with the economic subcriteria that observe the sustainable development goals that are met by each of the SUDS practices analyzed herein, considering that they must be met by 2030. The model proved to be slightly sensitive to changing scenarios. The technical subcriteria “soil permeability” and “groundwater level” proved to be decisive for the adoption of the listed SUDS practices. The application of the model in the study areas demonstrated that in locations where all SUDS practices could be used, the vegetated ditch excels among the others, whereas the infiltration trench is further away from the ideal solution. In more restrictive locations, bioretention cells and green roofs excel as solutions with the shortest distance to the ideal solution.
