Abstract: This paper shows the application of HAND model in a watershed located in Cerrado environment, in a macro and micro scale. HAND model was applied used diferentes thresolds and the results were classified according to four classes with hydrological significance. The HAND was calibrated based on the drainage network and the measurements performed in the groundwater field. In the small watershed 26 piezometers were installed throughout the basin for groundwater monitoring. The HAND model showed viable to represent the basin drainage, located in Cerrado environment, with most areas with high altitudes compared to the hydrography of the ANA. A problem was that in some regions the length of the drainage was less than the real, defining points of source in inappropriate places, but it’s a small error if we consider the magnitude of the watershed.
