Resumo: In the reservoirs of multiple uses of water, exist conflict to control floods, mainly for generation of electric energy. To control floods it's necessary an empty volume able to absorb an accidental flood without causing damage in the areas downstream. On the other side, to generate energy it's desirable to place the smallest volume of possible protection, whereas to control floods it's desirable to have a reliable estimate in case the reservoir fails when a given volume of protection is placed. The objective of this work was to construct the Volume Curve x Length, used to estimate the waiting volume, through the adjustments of the series of the affluent maximum volume using the distribution GEV and moments LH. Affluent volumes were used and observed in several fluviometrics stations of rivers in Paraná state, Brazil. All the adjustments of affluent maximum volumes were accepted through quality tests of proposed adjustments by Wang (1998). The volume curve x length was built properly using values of affluent maximum volumes observed in different fluviometrics stations.

Para controlar cheias é necessário um volume vazio capaz de absorver uma eventual cheia sem causar danos nas áreas à jusante. Por outro lado, para gerar energia é desejável alocar o menor volume de proteção possível, ao passo que para controlar cheias é desejável ter uma estimativa confiável da possibilidade do reservatório falhar quando um dado volume de proteção é alocado. O objetivo deste trabalho foi construir a Curva Volume x Duração, empregada para estimar volume de espera, através do ajuste das séries de volumes máximos afluentes usando a distribuição GEV e momentos LH. Foram usados volumes afluentes observados em várias estações fluviométricas de rios do estado do Paraná, Brasil. Todos os ajustes dos volumes máximos afluentes foram aceitos através do teste de qualidade de ajuste proposto por Wang (1998). A curva volume x duração foi adequadamente construída usando valores de volumes máximos afluentes observados em diferentes estações fluviométricas .Universidade Estadual De Maringá2007-12-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/9110.4025/actascitechnol.v29i1.91Acta Scientiarum.
