The maximum flows and design flows for hydraulic engineering works in Peru are obtained by hydrological processing of rainfall records measured at the hydrometeorological stations of the National Water Authority (ANA) and the National Service of Meteorology and Hydrology of Peru (SENAMHI). entities in Peru. For this reason, flow information obtained remotely through the Global Flood Awareness System (GloFAS) database for a gauging point in the lower basin (Socsi) is analyzed and evaluated. This was done through a statistical analysis and the application of downscaling for the readjustment of the satellite data. Software such as Microsoft Excel, Google Earth Pro, R Studio, ArcGIS and Hec-RAS were used during the process. The results obtained were a correlation coefficient of 0.94, a coefficient of determination of 0.68 and a Nash-Surcliffe efficiency of 0.87. These data indicate that the flow data has an excellent fit and are similar to the data measured in situ. The maximum annual flow of 320 m3/s was also obtained, which was used to simulate flooding in HEC-RAS and identify vulnerable areas in the lower part of the Cañete river, specifically in the district of Lunahuaná. In conclusion, the GloFAS satellite data adjusted by downscaling has a good similarity with the observed data from the Socsi station. Therefore, it can be used to estimate daily flows and maximum annual flows for the simulation of flood zones in the lower Cañete River sub-basin
