The data collected by gauges is crucial for hydrological studies, with different aggregation times characterized by sensor type and recording system. This review paper uses a comprehensive rainfall database from global rain gauge networks to analyze the temporal evolution of t(a). The discussion also highlights the importance of accurately determining extreme rainfall for designing hydraulic structures.
Data collected by gauges represent a fundamental force in most hydrological studies. On the basis of sensor type and recording system, such records are characterized by different aggregation time, t(a). In this review paper, a comprehensive rainfall database of rain gauge networks operative worldwide is used to determine the temporal evolution of t(a). As a second step, issues related to the limited and heterogeneous temporal resolution of rainfall data are discussed with regard to avoiding possible errors in the analysis of historical series. Particular attention is focused on quantifying the effects on the estimation of extreme rainfalls that play a crucial role in designing hydraulic structures. To this aim, algebraic relations for improving a correct determination of extreme rainfall are also provided.
