- Abstract
The article examines the bank collapse processes in a valley-bottom gully in western Iowa. It measures rainfall, air temperature, and hydraulic head near the banks and bank movement nearly continuously over a two-year period. The article shows that the styles of movement ranged from imperceptible creep to rapid slab collapses preceded by the formation of tension cracks parallel to the gully walls. It also suggests that bank movement was commonly correlated to rainfall or snowmelt and associated head increases in the banks.
