Hydric characterization of the Vaquerías watershed (Córdoba, Argentina) throught hydrological modeling and satellite information

Abstract

A hydrological characterization is presented, through computational modeling, of the Vaquerías watershed basin. This basin, lacking any monitoring system, represents the main source of water of the Vaquerías Natural Reserve (National University of Córdoba. CHIRPS (Climate Hazards group InfraRed Precipitation with Station data) was used as precipitation source data; MOD16A2 was used as evapotranspiration source data. Data was processed
through Google Earth Engine platform. The modeling was carried out through the TOPMODEL semi-distributed model, which in a simplified way considers the contribution of superficial and groundwater flows to the runoff. Despite the limitations of the input information and the implemented model, and in lack of field information, it was possible to carry out a hydrological characterization of studied watershed.
