You can now read this document / article, at https://alcatrazescapee.com/rivers/. It will be updated further there. The original content is still here, below

Why Are Rivers So Complicated?

Let's narrow that down a bit. This document will try to explain some of the difficulties, limitations, and possible ways to generate rivers in Minecraft. There have been many papers, articles, and other medium which have generated realistic rivers to great success. So what makes Minecraft so much more difficult, or what makes these other methodologies so difficult? And what methods have found success?

What the heck is up with configs in Forge >1.12?

In Forge versions > 1.12, there are multiple types of config files. Each of these have a specific purpose. So whenever you're looking for a config option, first make sure you're looking in the right file! So, what are the types?

Server Configs

these are unique per world.
located in the world folder, e.g. .minecraft/saves/<world>/serverconfig/modid-server.toml
automatically synchronized from server -> client
can be overriden (i.e. for the purpose of not having to edit the config every time you create a world) by the defaultconfigs folder - any server configs found under .minecraft/defaultconfigs will be copied to any new worlds when created (overriding the mod defaults)

	To honour the JVM settings for this build a single-use Daemon process will be forked. See https://docs.gradle.org/7.2/userguide/gradle_daemon.html#sec:disabling_the_daemon.
	Daemon will be stopped at the end of the build
