“…However, the behavior of exceptional rainfall is hard to determine, and is generally handled in a probabilistic way. These rains can be determined through rainfall intensity equations, which are broadly utilized for dimensioning drainage structures with different purposes, including agricultural (VIVEKANANDAN, 2017) and urban drainage systems (SABÓIA et al, 2017), channels (WRIGHT; SMITH; BAECK, 2014), and engineering structures in road projects (KANG et al, 2009). A precise characterization of rainfall intensity equations is therefore vital for the appropriate sizing of different drainage structures.…”
