Modelo iterativo para estimativa da evapotranspiração de referência provável

Abstract: RESUMO: O presente trabalho teve por objetivo a apresentação de um modelo iterativo para utilização em microcomputadores capaz de estimar valores de evapotranspiracão de referencia em diversos níveis de probabilidade, a partir de uma série de dados. O procedimento matemático envolvido na técnica iterativa empregada relaciona-se à utilização das funções de densidade gama incompleta e beta. Para tanto, foram utilizados dados quinzenais de evapotranspiracão do mês de março, a partir de uma série de 30 anos para a… Show more

“…It can be seen that the estimated reference evapotranspiration values with 75% probability through the Normal distribution vary according to the month of the year. Marques Jr., Saad and Moura (1995) adopted the concept of dependent precipitation, quoting Doorenbos and Kassam (1994), to apply the Table 1. Normal distribution of probability applied to the reference evapotranspiration variable (Eto) in the months of January, February, March, April, May, June, July, August, September, October, November andDecember, between 1970 and…”
