Abstract:

It has been suggested that sediment yields and landform evolution in steeplands of high-sediment production may be episodic that is, the fluvial system is in metastable equilibrium, and periods of erosion are separated by periods of stability or deposition. Episodic deposition as well as episodic erosion should be recognized in steeplands. The two when occurring within a fluvial system can be referred to as the episodic behavior of that system. A model study of episodic behavior was made in the Kraft Badlands in eastern Wyoming during the summer of 1978 bergstrom, 1980. In addition, experimental studies of sediment movement, drainage network and channel changes were carried out in the Rainfall-Erosion Facility during the summer of 1978 and a field check on the experimental results was made in the Little South Fork of the Cache la Poudre River near Fort Collins, Colorado Harvey, 1980 where a series of sediment samples were taken during the 1979 runoff season to document daily and hourly changes of sediment load and sediment type.
