Short Summary

This study evaluates and compares two global climate datasets (CPC and CFSR) and three evapotranspiration estimation methods (Turc, Papadakis, Thornthwaite) for hydrological balance in the Napostá Grande basin, recommending CPC data and Papadakis/Turc methods for accurate hydrological modeling.

Objective

• To evaluate and compare the reliability of two global climate datasets (CPC and CFSR) and different evapotranspiration estimation methods (Turc, Papadakis, Thornthwaite) to accurately represent hydrological balance components, particularly evapotranspiration, in a poorly instrumented basin.

Study Configuration

• Spatial Scale: Napostá Grande stream basin, Argentina (a medium-sized basin with predominantly agricultural development in a dry sub-humid climate).
• Temporal Scale: 1979-2013 for statistical analysis of climate data; 2012-2013 for annual water balance validation.

Methodology and Data

• Models used: Turc, Papadakis, Thornthwaite (for evapotranspiration estimation); SCS (Soil Conservation Service) method (for initial abstractions validation). A hydrological model was developed and validated.
• Data sources: Global climate datasets (CPC, CFSR) for daily precipitation, maximum and minimum temperatures; local meteorological records (for comparison and validation).

Main Results

• The study recommends using the Papadakis and Turc methods for estimating evapotranspiration due to their adequate reproduction of the observed climatological trend.
• The CPC data series are recommended for hydrological studies as they adequately reproduce observed climatological trends.
• The validation of the hydrological model corroborated both the interception component and the basin's curve number.

Contributions

• Provides a validated methodology for utilizing global climate datasets (specifically CPC) and specific evapotranspiration methods (Papadakis, Turc) to complete hydrological series in poorly instrumented basins.
• Develops a vital hydrological simulation tool for the Napostá Grande basin, enabling improved planning for human and industrial water supply and agro-food development, thereby promoting regional autonomy.
