Resumen
The hydrological analysis is a key process in engineering studies and structural works, precipitation-runoff methodologies are implemented in a global level with the objective of quantifying volume or flow and evaluate the possible contributions that may have events in a particular territory. This work developed a complement for the QGIS software called "WRE", it allows to users the integration of spatial and hydrological variables to apply the SCS-CN methodology of the conservation service of the United States, it involves the combination of the characteristics of coverages, soils, and hydrological parameters. As result, it was found a great improvement of times in the application of the methodology in the middle of the developed automation contributing with this to the precision in the results and diminishing the possible operative errors in the processing of the information.
