Geologic Mapping of Flood Hazards in Arizona: An Example From the White Tank Mountains Area, Maricopa County
Dataset Identification:
Resource Abstract:
Assessment of the character of flood hazards and the extent of flood-prone areas onthe piedmonts of Arizona is an increasingly
important concern to floodplain managers asurban areas continue to expand. Piedmonts are the low-relief, gently sloping plainsbetween
mountain ranges and the streams or playas that occupy the lowest portions of thevalleys. Proper management of flood hazards
on piedmonts is important because much ofsouthern, central, and western Arizona is composed of piedmonts; they comprise most
ofthe developable land around Phoenix and other rapidly expanding population centers of theState.Management of flood hazards
in Arizona and elsewhere in the western UnitedStates is complicated because portions of many piedmonts are composed of active
alluvialfans. During floods, these fans are subject to widespread inundation and local high velocityflow, and substantial
changes in channel patterns may occur. Development thatproceeds on piedmonts without regard to the locations of active alluvial
fans is likely toplace people and property at risk during large floods.Report and 4 map sheets.
