Abstract: Lower reaches of tributaries to the Missouri River, USA, were straightened in the late 19th and early 2oth century. channel degradation has progressed upstream as a result. Channel deepening and widening have caused problems at stream crossings and resulted in gully development in cultivated fields. A hyperbolic mathematical model for channel degradation was solved and fit to observed degradation of west Tarkio creek.
