Postglacial topographic evolution of glaciated valleys : a stochastic landscape evolution model

Authors(s) and Affiliation(s)



The AA. have studied the evolution of an idealized glaciated valley during the period following retreat of ice using a numerical model. The model incorporates a stochastic process to represent deep-seated landsliding, non-linear diffusion to represent shallow landsliding and an approximation of the Bagnold relation to represent fluvial sediment transport. It was calibrated using field data from several recent surveys within British Columbia, Canada. This model predicts a rapid rate of fluvial sediment transport following deglaciation with a subsequent gradual decline, similar to that inferred for Holocene time. The AA. also describe how changes in the model parameters affect the estimated magnitude and duration of the paraglacial sediment pulse
