Influence of rainfall time series sample rate in the improvement of decision-making based on high intensity rainfall events
Year: 2025
Type: article
Abstract: This study aims to assess whether data acquisition frequency can affect the understanding of high-intensity precipitation events. Time series from a weighing gauge and a weighbridge gauge installed at the same site were analysed, with rainfall intensity data acquisition frequencies of 10 seconds and 5 minutes, respectively. To check the consistency of the data obtained by the two types of rainfall measuring instruments, a correlation analysis was carried out between the two time series. The results relating to acquisition frequency showed that, for an acquisition frequency of 5 minutes, there are significant losses of information (especially during heavy rainfall events) compared to acquisition frequencies of 10 seconds. The correlation analysis showed that the gauges are measuring correctly and that the data is accurate.
