In the original paper, Zamani et al. (Nat Hazards 76:327-346, 2015. doi:10.1007/s11069-014-1492-x) analyzed droughts in arid and semiarid lands based on minimum streamflow values. In that article, drought index values at 3-, 6-, 9-, and 12-month time scales were analyzed by the SDI index and L-moment method. This article points out some problems about the L-moment method, which are discussed and corrected in this discussion.
