This study investigates the behavior of drought in the Huaura River basin using the Standardized Precipitation Index (SPI). The primary objective is to determine drought indices to identify water deficit in the basin for both agricultural and population use. Specific objectives were established: to geomorphologically characterize the basin, analyze the consistency of monthly precipitation data from the period 1963-2022, calculate drought values using the SPI, and estimate water availability. The SPI methodology is valued for its ability to analyze different temporal scales and types of droughts, being easy to calculate and interpret. It transforms accumulated precipitation data into normalized probabilities, facilitating the identification of drought periods. The study used data from meteorological stations and tools such as HEC4, Hec-hms, ArcGIS, Hydraccess, and Rstudio software. The results show significant variations in the intensity and frequency of droughts over the studied period, with critical events associated with phenomena such as El Niño. The probability of occurrence of moderate, severe, and extreme droughts in the basin was classified. In the upper part of the basin, extreme droughts have a frequency of 2.4% out of a total of 709 events for hydrological drought, and a frequency of 2.65% out of a total of 718 events for agricultural drought. It is concluded that the SPI is essential for planning and mitigating the impacts of droughts on agriculture and water resource management in the region, providing a solid basis for informed decisions.
