Soil Erosion Drainage Map (2D)

A top-down 2D drainage-basin view of the same stream-power erosion model as the 3D Soil Erosion & Runoff slope profile: rainfall, slope and vegetation cover carve a real dendritic gully network across a field instead of a single cross-section.

This 2D companion trades the 3D hillslope profile for a top-down drainage-basin view of the exact same physics: a steepest-descent flow-routing grid feeds the same stream-power erosion law (E ≈ k·(S·A)^1.5) used by the 3D Soil Erosion & Runoff simulation, driven by the same rainfall, slope, vegetation cover and soil-type variables. Instead of watching one cross-section carve into a single valley, you watch an entire field organise its rainfall into a branching gully network from above — the same equations, a genuinely different view of what they do.
