Dept. of Civil and Environmental Engineering , Massachusetts Institute of Technology . Animation of 3000-year simulation of forest growth, death by fire, storms, soil production and diffusion, landslides, debris flows, and fluvial sediment transport. Following debris flow events, thick deposits appear throughout the network. They seem to melt away as the wood constituent decays.
Fluvial transport reworks the sediment.
A simple model of river meandering and its comparison to natural channels , by S.T. Lancaster and R.L. Bras, in press, Hydrological Processes , 2001. In the animation , the model stream flows from top to bottom. When the stream channel encroaches on a pixel, its elevation is automatically set to that of the channel bed. Once the channel vacates a pixel, its elevation is left at the elevation of the channel bed at the bank. Because the grid points surrounding the channel are uplifted at a uniform rate, elevation of a pixel is proportional to the time since that pixel was occupied by the channel.
