This study was conducted between September 2023 and August 2024 in order to evaluate the spatial and temporal changes in the chemical parameters of rainwater in Sivas City Center using multivariate statistical approaches. It was determined that the rainwater quality in Sivas City Center was not acidic. In the study conducted, no statistically significant difference was found in terms of stations (P>0.05), while statistically significant differences were found in terms of seasons (P<0.05). Therefore, it is important to take into account seasonal changes in chemical parameters when determining and implementing managerial strategies for rainwater in Sivas City Center. As a result of examining the principal components and eigenvalues, two factors were formed in the data, and these two factors together explained approximately 70.43% of the total variance. While hierarchical cluster analysis revealed that the winter season differed from the other seasons, it also showed that station-4 was distinct from the other stations. The rainwater parameters analyzed in Sivas City Center exhibited changes at both temporal and spatial scales, and the results of this study can be used to provide important data and information support for sustainable and effective rainwater management, especially for Sivas City Center.
