Abstract: Abstract There is increasing attention to the development of a myriad of complex methods for nonstationary frequency analysis (NFA) of floods, droughts and other hydrologic processes. We assume that the need for NFA arises from well understood deterministic mechanisms of change. A common assumption in NFA, questioned here, is that more accurate estimators of hydrologic statistics result when more realistic, complex and sophisticated models are employed. By considering the mean annual flood (drought or other hydrologic event), general conditions...
