MULTIFRACTAL POINT-OF-VIEW ON RAINFALL INTENSITY-DURATION-FREQUENCY CURVES

Intensity-duration-frequency curves, which are very useful for many de sign applications, are generally empirically drawn from point rainfall time series. Such point time series can also be analyzed from a multi fractal point of view and universal parameters characterizing the seri es can be estimated from empirical data. We derived from the scale inv ariant relationship of multifractals the formal equations of intensity -duration-frequency curves, which depend on only a small number of the series multifractal parameters. A rational basis is thus given to the se curves, which can be related to some objective parameters.
