FLOOD-HAZARD ZONATION IN ARID LANDS
Potential flood hazards in arid southern and western Arizona stem from different geomorphic and hydrologic characteristics and can be grouped into zones. The zonation is based on the physical features of the terrain, the sources of flooding, the expected frequency of flooding, and the expected erosion and sediment deposition. Various combinations of these factors create differing degrees of hazard. Distributary flow areas have stream channels that convey only a small fraction of the 100-year peak discharge and channels that can completely fill with sediments during a single flood. A basic understanding of the common and different flood hazards of areas in southwestern Arizona can lead to effective flood-plain management and design of hydraulic structures.
