Evaluation of hydrological parameters of the Goiana River basin in the State of Pernambuco using the automatic calibration tool of the hydrodynamic model PCSWMM in multiple fluviometric stations

The objective of this study was to perform a sensitivity analysis and automatic calibration the hydrological parameters Goiana river basin in state Pernambuco. A modeling structure for built using PCSMMM (Personal Computer Storm Water Management Model) hydrodynamic model analyzes were carried out 10 sub-basins. Based on developed basin, resources available PCSWMM calibration, known as SRTC (Sensitivity-based Radio Tuning Calibration), explored initially evaluate most sensitive then parameters. daily flow data extracted 5 fluviometrics stations present main water courses precipitation pluviometric stations. results simulations analyzed following statistics: Integral Square Error (ISE), Nash-Sutcliffe Efficiency (NSE), Determination Coefficient (), addition qualitative hydrograph modeled relation observations. Curve Number (CN) Manning's roughness permeable ones. In three control points (Engenho Retiro, Caricé Nazaré) SES values 0.919, 0.899 0.884, respectively. results, general, indicate very satisfactory performance tools model, besides being effective traditional approaches by trial error.
