As far as we know, the erosion device emulates the erosion caused by rain droplets carrying small amounts of depositions, but does it also take water systems into account, and with that, does it support fluvial erosion? If not, would it be possible to add fluvial erosion to WM for better water simulation? To our understanding, the Flow Restructure device and Create Water device already have “knowledge” regarding “all water from this area goes through this point and creates a river”, something fluvial erosion would also require, indicating it is possible to implement?
And thinking of it, this may help with the problem the Erosion device has with existing water systems, as described here. The create water device and erosion device would sort of “merge” then.
