Thus, with the main objective of evaluating the influence of recent additions to historical data series on the determination of design rainfall intensity values, based on the establishment of intense rainfall expressions (IDF expressions) and pairs of return period and time of concentration recommended by DNIT and DER/SP, five Brazilian cities were selected, one in each region of the country (Castanhal/PA – North; fortaleza/CE – Northeast; Terenos/MS – Central-West; Belo Horizonte – Southeast; and Guaíba/RS – South). Five rainfall stations located in these cities were chosen, and for each one, four IDF expressions were established by varying the amount of rainfall data in their historical series through the inclusion of 1, 5, and 10 years of the most recent records, counted up to the end of 2024. The results obtained indicate that the standard deviation of the data sample plays a dominant role in determining the highest values. Furthermore, they show that extending the rainfall records of the selected stations by one, five, or ten recent years generates differences in design rainfall intensity values of at most 9.09%, suggesting causes other than the increase in design rainfall intensity due to climate change for the rise in discharge and occurrences of drainage system insufficiency. However, this does not mean that rainfall data from subsequent years can be disregarded.Acesso AbertoIntensidade de chuva de projetoMudanças climáticasEquações IDFSéries históricas de dados de precipitações no BrasilInsuficiência de sistemas de drenagemDesign rainfall intensityClimate changeIDF equationsHistorical rainfall data series in BrazilDrainage system insufficiencyCNPQ::ENGENHARIAS::ENGENHARIA CIVILTrabalho de Curso - Graduação - MonografiaAttribution-NonCommercial-NoDerivs 3.0 Brazil
