Abstract

Two catastrophic events, occurring simultaneously in the valley of Little Grassy Creek, allow for an examination of the threshold concept in geomorphology. Movement of debris associated with failure and sliding of valley-side material, caused damming and avulsion of Little Cassy Creek. Slope and river disruptions were linked because the effect of one event (slope failure) was the cause of the second event (fluvial avulsion). Criteria needed to employ thresholds to explain geomorphic events are suggested, and a definition of thresholds as time-dependent phenomena is presented as a means of reducing confusion over the use of the threshold concept
