Abstract
Hydrologic simulation is an important tool for the planning and management of water resources. However, the lack of input data, particularly soil and climate data, frequently complicates the application of hydrological models in Brazilian Atlantic Rainforest basins. The purpose of this study was to analyse the application of the VIC model, under the condition of low data availability, to predict the daily streamflow of two basins (Jucu and Santa Maria da Vitória). The results showed satisfactory statistical indexes only for the Santa Maria da Vitória basin. Due to data limitations and the simplified forms used to estimate these missing data, the model proved promising for understanding the hydrologic regime of these basins.
Highlights
Achieving sustainability of water resources is difficult because many conflicting factors must be balanced due to the complexities of the watersheds (Zhang, Li, Huang, & Liu, 2014)

Summary
Achieving sustainability of water resources is difficult because many conflicting factors must be balanced due to the complexities of the watersheds (Zhang, Li, Huang, & Liu, 2014). After a consistent calibration (Wallner, Haberlandt, & Dietrich, 2013), some hydrological models developed for major basins were applied to smaller watersheds. These applications resulted in promising performances (Cuartas et al, 2012; Pinto, Silva, Beskow, Mello, & Coelho, 2013) and necessitated more studies as these models generally required less input data than lower scale hydrological models. Professionals involved in water resource management face the need to develop, improve and apply tools for solving water quantity and quality problems, including hydrological models (Bressiani et al, 2015). The purpose of this study was to analyse the application of the VIC model, under the condition of low data availability, to predict the daily streamflow of the Jucu and Santa Maria da Vitória basins
