Resumen:
In this dissertation the runoff modeling in watersheds within the lower part of the
Paraíba river basin (3925,41 km2), and Mamanguape (3522,69 km2) was carried out with
the distributed model NAVMO, which is capable of considering the variability of the
climate (e.g., precipitation) and catchment system (e.g., soils, relief, land use), in order to
support future regional analyses in the whole river system, in order to realize the hydrologic
regionalization in the whole river system. The model was calibrated by comparing annual
values of volumes and peaks, as well as daily hydrographs, and verified via different
criterions. The results showed that the calibration was successfully accomplished for the
few catchments where data are available, with mean coefficients of determination (R2) of
0.7976 (volumes) and 0.8392 (peaks). The mean values of R2 for the validation phase were
lower than those from the calibration, 0.2591 (volumes) and 0.2448 (peaks), but with
reasonable comparisons of the daily hydrographs.
