برآورد رگبار طرح با استفاده از تئوری مالتی فرکتال در ایستگاه سد گتوند

Design storm is required for designing of hydraulic structures but its current estimation methods are criticized by hydrologists since these method need many parameters and requires the rainfall data at different durations. Nowadays fractal theory is used to improve the estimation of design storm which has few parameters and the design storm at different durations and with any return periods is estimated only from annual ۱-day maximum rainfall series. In this research, fractal theory was used to estimate the design storm in Ghotvan Dam site. The results showed that momofractal model underestimated the design storm, but the estimated design storm by multifractal model was consistant with the observation data.
