Hey everyone, ahm gonna do a scenario based on the Inkas. So, I need sum help on how to create rivers and flood plains. Ok, all i can tell you is that i'm going to tell u is i'm going to make a city in the mountains. The palace is atop land, peeking over the city and mountains, the city will be under the castle and the farmers will harvest...
uh oh! too much info. you'll have to see for yourself when the scenario comes out.
And that won't be a long time from now!;)

Sounds good. :) When making rivers and floodplains, remember that they're at specific elevation settings only. -1 is floodplain level and everything below that is river. 0 is flood-prone terrain and 1 is safe terrain. After you've "carved" a river through the terrain, click on the "create river" button.
