Spatially distributed hydrological models have been a powerful tool for indirect survey information of a watershed. In this study, the hydrological behavior of two basins located on the coastal edge of the Araucania region is characterized. The method is based on a process of spatially distributed hydrological modeling with WARPHydro and ArcHydro softwares. The results showed differences in behavior between the two hydrological basins attributed to the shape of the water supply, altitude and surface runoff. We conclude that when there is a lack of field data and costs limit the use of other methods, hydrologic modeling generates information base for decision-making on water management.
