. Wavelet threshold de-noising (WTD) is a
powerful tool for de-noising the hydrological data, and is better than traditional
Fourier transform or traditional spectral analysis methods. However, the perfor-
mance depends on the suitability of selected wavelets and decomposition level
choice and threshold estimation in de-noising. The methodology adopted by Sang
et al. [
