Link Earthworks: Gully Modeling from Using GRASS, NumPy...Modeling

[wenzeslaus]

A box should say something like "For creating stream network with gullies using GRASS, see Earthworks: Gully Modeling."

(unrelated, but small:) Also, "AI edited landscape" should be something like:

1. AI-modified landscape
2. Landscape with an AI filter adding realism
3. AI-enhanced landscape rendering for visual realism
4. AI-touched landscape with a hint of realism
5. Landscape enhanced by AI with a touch of realism
6. Landscape touched by AI for a hint of realism
