Abstract

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.
