Bedrock erosion model comparison

Lab material developed for GY320 at Colorado College. This exercise compares different formulations of bedrock erosion and the effects of each on landscape form, drainage network patterns, and long profiles. The comparison involves Fastscape, a simple stream power erosion model, and a stream power erosion model with sediment. The values of m and n can also be changes to switch from a shear stress to stream power model. A simulated landscape is run for 1 My with diffusion and the tested erosion model and the resulting topography, drainage pattern, and long profile is output. The model is run using the Landlab toolkit (https://landlab.github.io/#/) with the LinearDiffuser, FastScapeEroder, StreamPowerEroder, ErosionDeposition, FlowAccumulator, and DepressionFinderAndRouter components.
