## What it is
A Unity project that simulates hydraulic erosion on heightmap terrains to make procedurally generated landscapes look more natural. It includes an interactive demo and applies droplet-based erosion over many iterations.

## Use cases
- make procedural terrain look more natural with erosion
- simulate hydraulic erosion on a heightmap
- generate realistic mountain and valley shapes for games
- learn how erosion simulation algorithms work
- post-process noise-based terrain meshes

## When to choose
- you use Unity and want natural-looking procedural terrain
- you want a readable reference implementation of hydraulic erosion
- you are following along with the author's educational video

## When to avoid
- you need a standalone tool without Unity
- you need real-time erosion in a production game engine pipeline
- you need geologically accurate hydrology simulation

## Facets
- artifact type: application
- maturity: maintenance
- function: simulation, graphics, game-engine
- domain: simulation, graphics
- platform: cross-platform, game-engine
- tags: hydraulic-erosion, procedural-terrain, unity, heightmap, procedural-generation, game-development
