INTRODUCTION
•Tropical soils have peculiar hydrological caracteristics
For example:
Oxisols high ammounts of clay high permeability

2014 International SWAT ConferencePorto de Galinhas - PE
MODEL SETUP AND EVALUATION
•The evaluation was performed using a 10 years record of streamflow historical data (1989-1998)
•Monthly and daily basis
•The analysis was made without calibration using only SWATs first simulation.

MODEL SETUP AND EVALUATION
•Accuracy quantification and the criteria used for evaluation of SWAT’s streamflow simulation were made by ASCE (1993) and Moriasi et al. (2007) methods.
