Abstract:

A model for an idealized transect across a marsh channel-and-platform. The model simulates channel morphological evolution from sub-tidal to millennial time scales. In particular, the model explores the effect that creep has on channel bank dynamics, e.g., bank slumping. The model is written in Matlab.
