Notes on river generation:

• Sapiens approach: expands from ending points
• [Entropomorphic approach] (https://www.reddit.com/r/proceduralgeneration/comments/ce22d4/improved_river_generation_now_with_code/)
• Fractal river basins: chance and self organization: discusses some theory, empirical relations
• Red Blob Games on procedural elevation:

1. Grow rivers up from coastlines
2. Mark watersheds from rivers
3. Determine elevation
