Less insane river deltas

[NetSysFire]

Is your feature request related to a problem? Please describe.

When following a river, there is a good chance it will eventually escalate into a giant delta.

Solution you would like.

1. New England has no such insane river deltas.
2. There are no known river deltas this giant in the entire world.

In general, control branching of rivers. It might be related to why these insane deltas are created in the first place.

Describe alternatives you have considered.

This is probably out of scope, but in general, I'd like to see more smaller rivers and fewer large ones, in addition to reducing delta-ing. There are maybe a dozen waterways in the northeast over 100 yards wide for any meaningful stretch (Kennebec, Piscataqua, Merrimack, & Connecticut rivers come to mind), but it seems like in cata there is at least one good sized river running through every overmap. I'm not sure what a map tile is supposed to correspond to even roughly in terms of 'IRL distance' but they feel much too wide in most cases.

Many of the waterways in NE (speaking from personal experience living and hiking there, as well as many hours looking at satellite maps) are very small, no more than streams - yet this category of waterway is not modeled at all. This is especially true once you leave the coastal areas and get up into the more mountainous regions. Something akin to roads for water to break up the vast expanses of field and forest would provide a nice touch of verisimilitude.

Might be unrelated, but #38894 attempted to fix river generation. I don't remember if it actually fixed river deltas, but the screenshots looked promising.

Interesting, It seems like a cool project. I am not sure why the PR opener closed it without merging it? I guess they couldn't get it to work or something?
It had two things on the todo list for the PR not completed from what I can tell.
Not remembering the river scale between maps is probably why it didn't get merged.
I am not sure how something like that would be fixed. But, it would be cool if someone who was more familiar with the C++ side of mapgen could implement that last bit to get that merged.
