This dataset contains data from 10 simulations using a landscape evolution model. A landscape evolution model simulates how uplift and rock incision shape the Earth's (or other planets) surface. To date, most landscape evolution models exhibit "extreme memory" (paper: https://doi.org/10.1029/2019GL083305 and dataset: https://doi.org/10.13012/B2IDB-4484338_V1). Extreme memory in landscape evolution models causes initial conditions to be unrealistically preserved.
This dataset contains simulations from a new landscape evolution model that incorporates a sub-model that allows bedrock channels to erode laterally. With this addition, the landscapes no longer exhibit extreme memory. Initial conditions are erased over time, and the landscapes tend towards a dynamic steady state instead of a static one.
There are 2 animations for each simulation, which totals for 20 animations (10 simulations x 2). For each simulation, there is 1 animation that shows elevation and 1 animation that shows drainage area over time. Elevation depicts the height of the landscape, and drainage area represents a contributing area that is upslope. There are 20 folders in the dataset, and each folder contains:
>1000 .asc raster files
>1 .wmv formatted movie
>1 .mp4 formatted movie
The associated publication for this dataset has not yet been published, and we will update this description with a link when it is.
