DifferentialLinearDiffusion

class fastscape.processes.DifferentialLinearDiffusion(*, shape, elevation, fs_context, diffusivity_bedrock, diffusivity_soil, soil_thickness)

Hillslope differential erosion by diffusion.

Diffusivity may vary depending on whether the topographic surface is bare rock or covered by a soil (sediment) layer.
