This study proposed to develop and implement a calibration routine hydrological
models applied to urban drainage using multiobjective optimization techniques. To make this
work possible model was adopted Storm Water Management Model (SWMM) and the
computational algorithms developed in MATLAB environment using an evolutionary
algorithm. The method was applied to two different levels of detail in representing the Arroyo
Cancels basin, located in the urban area of Santa Maria-RS, submitted to the hydrological
processes involved in the process of rainfall-runoff transformation in the search for optimal
values of hydrological parameters the basin. Objective functions were defined and applied
simultaneously in the calibration parameters. Worked with the simulation of events of low
and high intensity settings for two discretization of the watershed, and other simple and
subdivided into 18 sub-basins. The sensitivity analysis performed made it possible to check
that the parameters that most influenced the basin were simple: Percentage of impervious area
and outlet width. Regarding the results for the various watershed discretization can be seen
that in most cases when working with a more detailed watershed they were better, except for
some isolated events. Overall the model showed better results when high-intensity simulated
events for the best compromise solutions, thus showing the importance of using a
multiobjective model.
