The Santa Cruz River in southeastern Arizona has a long history of channel instability. Since the late 19th century, lateral channel erosion has caused extensive property damage, particularly in Pima County. The dominant mechanism of channel change in a reach depends on channel morphology and flood magnitude. The timing and magnitude of channel change are controlled primarily by hydroclimatic factors. The location of change is controlled largely by topographic, geologic, hydraulic, and artificial factors.
