    Recent laboratory experiments have shown that bed mobility in gravel bed channels responds to changes in sediment supply, but detailed examinations of this adjustment in natural channels have been lacking, and practical methodologies to measure bed mobility have not been tested. We examined six gravel-bed, alternate-bar channels which have a wide range in annual sediment yield (2 reaches of Redwood Cr., Jacoby and Grouse Cr. in northern California, and Gunnison R. and Williams Fork in Colorado).
