“…Apart from the advantage of estimating the PI, the PF technique also simultaneously quantifies the model parameter uncertainty resulting from the PI. This provides valuable information like the percentage of observed streamflow values encompassed within the PI, the deviation of the ensemble mean from the observation, the over or under‐estimation of the streamflow, and the symmetry around the observation (Sen et al., 2020; Tandon et al., 2022). The PF technique, however, suffers from the drawback of particle degeneracy (please refer to the Appendix for details on particle degeneracy), which was reduced by selecting the appropriate resampling technique (Boli'cboli´c et al., 2004; Elfring et al., 2021; Kuptametee & Aunsri, 2022; T. Li et al., 2015).…”
