| ====== Fluvial Erosion ====== | ====== Fluvial Erosion ====== | ||
| - | Wilbur sports a fluvial erosion model in addition to the incise flow operation. Incise flow requires a connected drainage system for best effect. The fluvial erosion system works either way. Wilbur uses a fluvial erosion model based on the precipitin or waterbot models. It randomly drops an agent onto the surface and that agent travels downhill, moving altitude from the higher cell to the lowest one adjacent to the current one until it finds a low spot. | + | This header was moved to [[wilbur:fluvial-erosion-tutorial|Fluvial Erosion Tutorial]]. |
