Time series, also called historical or chronological series, are sets of observations collected in an orderly manner over time. Studies of meteorological variables, such as flow, have been increasingly disseminated due to extreme events of climate change. The present work applied the time series methodology to the flow data of the city of Cuiabá (MT) in the period from 1933 to 2016, having Software R as its main tool, in a simple way, describing how alternative we can analyze time series using the free software R, this article aimed to search for Trend verification, using the Mann-Kendall test. In this context, to achieve this objective, the methodology used was quantitative research based on case study. It was concluded that the use of the Mann-Kendall non-parametric test in Free Software R satisfied the research interest, fulfilling the execution of the methodology stages.
