Application and calibration of an integration of the TREX and SWMM models for distributed hydrological-hydraulic simulation in a strongly anthropized basin

| Sumario: | This paper is about the application and calibration of a spatially distributed model in the watershed of Cascabel river, in the state of Parana, Brazil. For this reason, first a TREX model previously adaptated is used to model elements of the urban watersheds, sucha as storminlets, and then the semidistributed SWMN model is used to simulate the flow in the conducts and channels. The basin data were collected and processed to carry out these works, as for example the correction and adaptation of the digital elevation model, the maps about the land types and its uses, the survey about the location of the storm inlets and conducts. Finally, a series of events were selected (pairs of measured rainfall and liquid flow data) to perform the calibration of the model for the basin studied. The work presents the results of the calibration of five selected events, obtaining an acceptable fit of the model. In this way, it was concluded that the models used as a whole allow the complete simulation of an urban basin. In particular, the characteristics of TREX allow the use of raster information, speeding up data entry for the fully distributed modeling of an urban watershed. |
