Description :
A drainage basin simulation model is used to interpret the morphometry and historical evolution of Mancos Shale badlands in Utah. Field relationships and simulation modelling indicate that the badlands have resulted from rapid downcutting of the master drainage below an Early Wisconsin terrace to the present river level, followed by base level stability. As a result, Early Wisconsin alluvial surfaces on the shale have been dissected up to 62m into steep badlands, and a Holocene alluvial surface is gradually replacing the badland slopes which are eroding by parallel retreat.
