ABSTRACT
The objective of this work was to present an analytical and alternative method to measure the maximum probable rainfall intensity (mm.day-1),in situ . This method is based on Normalized Rainfall Curve (NRC) depicting the association between accumulated percentage rain amount (x) and cumulated percentage number of rain days (y) of the rainfall series. This method was applied to daily rainfall data at five stations (João Pessoa, Areia, Campina Grande, Soledade and Sousa) in the state of Paraíba. The results were considered very good in all the cases. Thus, the estimates for maximum probable rainfall intensity are reliable and these results can be quite useful in the planning of small hydraulic projects.
Key words:
