- Abstract
The aimed was to evaluate the precipitation by the coefficient of rain, the payback period and the probability of occurrence, in order to implement appropriate conservation measures aimed at the sustainable development of agricultural activity in the north of the Espírito Santo. The rainfall data were provided by the National Water Agency - ANA. These were obtained in Climatological stations called Itauninhas, Barra Nova, São João da Cachoeira Grande and Boca da Vala in the municipality of São Mateus in northern Espírito Santo. It was determined the rainfall coefficient (Rc), the return period and the probability of occurrence. The maximum values of total precipitation and maximum rainfall coefficient amounted to 11183.4 mm, 7778.4 mm, 5885.3 mm and 3528.6 mm Itauninhas, Barra Nova, São João da Cachoeira Grande and Boca da Vala, respectively. The maximum values for the rainfall coefficient for Itauninhas, Barra Nova, São João da Cachoeira Grande and Boca da Vala were 163.3 mm, 193.8 mm, 142.7 mm and 110.5 mm, respectively. Return periods for the most rainfall coefficient value were 67 years (Itauninhas), 45 (Barra Nova), 35 (São João da Cachoeira Grande) and 23 years (Boca da Vala). For climatological stations Itauninhas, Barra Nova, São João da Cachoeira Grande and Boca da Vala, the precipitation values are higher than the rainfall coefficient, for the months January to December, for the respective time series. The variation of the probability of occurrence is 1.5% to 4.35%, Itauninhas and Boca da Vala, respectively.
