PALAVRAS-CHAVE Irrigação Distribuição Gama Uso da água ABSTRACT: The occurrence, distribution of rainfall and the knowledge of crop water demand are essentials to irrigation planning. Thus, the determination of probable rainfall can contribute substantially to suitable irrigation projects. This work aimed to determine the probable rainfall for Uberlândia, Minas Gerais state, Brazil, in order to...

Tthe Zografos–Balakrishnan-log-logistic (ZBLL) distribution is a new distribution of three parameters that has been introduced by Ramos et el. [1], and They presented some properties of the new distribution such as its probability density function, The cumulative distribution function, The  moment generating function, its hazard (failure) rate function, quantiles and moments, Rényi and Shannon ...

[1] We analyze the propagation of daily fluctuations in rainfall and potential evapotranspiration to soil moisture dynamics, using a stochastic model that accounts for these two different forms of hydroclimatic variability. The pulsing, intermittent behavior of daily precipitation is described by a compound Poisson process that models the unpredictability of both frequency and amount of rainfal...

The Maximum Entropy probability density function associated with the testable information on the range and the first and second order moments of the random quantity of interest is derived. The validity of such approach is experimentally demonstrated through comparison between the proposed maximum entropy distribution and the Ushaped distribution. The underlying physical assumptions which must b...

The compatibility of quantitative and quali­ tative representations of beliefs was studied extensively in probability theory. It is only recently that this important topic is consiJ­ ered in the context of belief functions. In this paper, the compatibility of various quan­ titative belief measures and qualitative belief structures is investigated. Four classes of be­ lief measures considered ar...

 The ratio of independent random variables arises in many applied problems. In this article, the distribution of the ratio X/Y is studied, when X and Y are independent Rice random variables. Ratios of such random variable have extensive applications in the analysis of noises of communication systems. The exact forms of probability density function (PDF), cumulative distribution function (CDF) a...

Drought indices are used to identify and monitor drought events. The standardized precipitation evapotranspiration index (SPEI) is a widely based on accumulated water balance. There is, however, no broad consensus which probability distribution the most appropriate for balances. This issue investigated Ethiopia using 125 meteorological stations spread across country. Based long-term series, sel...

Planning of water resources and its management with the ambiguity non-uniformity accompanying precipitation other meteorological physical characteristics may perhaps effect on agricultural production in Bihar where farmers mostly depend precipitation. The potential evapotranspiration temporal distribution state is irregular due to geomorphology, climatic anthropogenic factors state. In present ...
