abstract = "Hydrological modeling procedures applied to regulatory flood-hazard zonation can be misapplied when assumptions concerning flood-hazardous processes are violated. Geomorphological mapping of the Tortolita Mountain piedmont in southern Arizona reveals extensive high-standing nonhazardous inactive, relict Pleistocene fan surfaces within zones mapped by FEMA as subject to active alluvial fan processes and 100-year flooding. Paleoflood analysis of upstream mountain canyons documents that maximum flood discharges for the past century have been about 50\% lower than the regulatory (100-year) flood discharges. Geological studies are essential complements to engineering models in order to generate public confidence that regulatory requirements derive from knowledge of real rather than idealized arid-region flood-hazard processes.",
