Intermittent streams can be found in many different climate regions. For example, arroyos are intermittent streams that erode deep vertical channels through fine sediment in arid and semiarid regions in the American Southwest during precipitation events. Many incised arroyos that are destructive to stream beds and adjacent man-made structures were formed as a result of drainage channelization and overgrazing during the late nineteenth century along with the influx of American settlers in the Southwestern United States.
