A New Generalized Modified Weibull Distribution

We introduce a new distribution, so called A generalized modified Weibull (NGMW) distribution. Various structural properties of the distribution are obtained in terms Meijer's $G$--function, such as moments, moment generating function, conditional mean deviations, order statistics and maximum likelihood estimators. The exhibits wide range shapes with varying skewness assumes all possible forms hazard rate function. NGMW along other distributions fitted to two sets data, arising hydrology reliability. It is shown that proposed has superior performance among compared evidenced via goodness--of--fit tests
