Instead of Fourier smoothing, this study applied wavelet denoising to acquire the smooth seasonal mean and corresponding perturbation term from daily rainfall and runoff data in traditional seasonal models, which use seasonal means for hydrological time series forecasting.
The denoised rainfall and runoff time series data were regarded as the smooth seasonal mean.
The probability distribution of the percentage coefficients can be obtained from calibrated daily rainfall and runoff data.
For validated daily rainfall and runoff data, percentage coefficients were randomly generated according to the probability distribution and the law of linear proportion.
Multiplying the generated percentage coefficient by the smooth seasonal mean resulted in the corresponding perturbation term.
Random modeling of daily rainfall and runoff can be obtained by adding the perturbation term to the smooth seasonal mean.
To verify the accuracy of the proposed method, daily rainfall and runoff data for the Wu-Tu watershed were analyzed.
The analytical results demonstrate that wavelet denoising enhances the precision of daily rainfall and runoff modeling of the seasonal model.
In addition, the wavelet denoising technique proposed in this study can obtain the smooth seasonal mean of rainfall and runoff processes and is suitable for modeling actual daily rainfall and runoff processes.
