Resumo
In water management projects, mainly those related to
water accumulation or conduction, the knowledge of expected
precipitations for the different conditions is fundamental.
The objective of this research was to determine the expected
maxima precipitation for different Times of Return (TR), for the
Central and Southeast regions of the Goiás State, Brazil. Daily
precipitation data of 36 rain gages were used, obtained from the
Brazilian National Water Agency (ANA) database, organized in
an electronic worksheet and treated by the Kimball methodology
for TR determination. The results indicated that differences
between extreme values of maxima precipitations, for the same
TR, exceeded 50% the lower precipitation values. This study also
showed that the Northwest and Southeast regions of the studied
area present large precipitation values, and the Central and East
regions present lower values. These results emphasize the need
for adoption of local values for planning hydraulic projects.
