Getting a river on a Hill
« on: December 24, 2008, 01:40:31 am »

Is it possible to find a location with a river on a hill, right next to a valley? I have some ideas for my next fort that require such a scheme.

I mean, it makes sense that all rivers are on the lowest above ground z-level, they eroded their way there, But is it possible to get that river on a hill?

Sort of.  Erosion works region tile by region tile, or something like that.  Occasionally, you can find a quasi-bug where a brook or river will continue on at the same level while the mountain it was on drops from wind erosion.  So you get this tiny isthmus of river jutting out into the sky.

You could also pump the water of a normal river up the hill. One waterwheel powers a few pumps, so you probably need one waterwheel for every 5 z-levels, or something.

waterfalls used to be fairly common back when every hill and elevation change was a sheer cliff face.  i havent seen any since the hill-smoothing thing.

I've seen a two-z-level one recently. Wasn't that impressive. Also, the lower part of the river started muddy.

I found an area where two rivers fell into a valley, creating two waterfalls right next to each other. The map was cold so the waterfalls froze. I then dug into the ice wall with my starting seven, walled it off so the water wouldn't flood, and had my 7 stay down there while my migrants had to live outside.

I've actually seen a few 7 z lever major river waterfalls (however, it was only a 20 tile major river, not a 30+ tile one unfortunately).

I think You might be best served genning your worlds in older versions and moving the save over after you've gotten a nice water fall.  I used to get at least one in every large map I genned back in 38c
