Hydrological modeling in a basin of the Brazilian Cerrado biome

The Brazilian Cerrado biome (BCB) is among 25 biodiversity hotspots identified worldwide, and covers the recharge area of important aquifers rivers in South America. increase deforestation has been threatening water availability this region. In order to assist water-resource management BCB, study models daily streamflow a basin Cerrado, using two approaches: process-based model (Soil Water Assessment Tool - SWAT) data-driven (Artificial Neural Network ANN). performance was evaluated by Nash-Sutcliffe coefficient (NSE), determination (R2) flow-duration-curves (FDC). results indicate that SWAT (NSE > 0.61; R2 0.68) ANN 0.91; 0.79) are suitable tools modeling studied basin, with being most accurate. Based on FDC, also better than for all frequencies evaluated. Thus, promising new approach modelling Moreover, can help managers planning implementing appropriate allocation conservation measures biome.
