Abstract

Rainfall was analyzed in daily resolution through the concentration index (CI) of Martin-Vide (2004). The 70 pluviometric series were obtained from the National Water Agency (ANA) through the HIDROWEB site. The calculation of this index was performed using the R environment, with the precintcon subroutine. The study period was from 1976 to 2015.The results showed values between 0.51 and 0.71, latitudinally increasing from
north to south in the study area. The rainfall percentage also showed a gradient with increase from north to south in the state.

Keywords: Concentration ratio, daily precipitation, exponential curve.
