I added a bit about temporarily draining and permanently damming rivers and linked to a movie I recorded of doing just that. I think there are ways that would be easier on the dwarves and less micromanagey - one way, perhaps, may be to blast a 3-wide section of the river floor, instead of a 1-wide one, and then build floors in the middle column, and then build floodgates on top of those - that should keep the pesky backflow (which made installing the floodgates so arduous) from interfering with the damming. --[[User:SL|SL]] 00:28, 30 November 2007 (EST)

== Draining brooks ==
 +
 +
I made following experiment:
 +
 +
*1. Built a bridge over brook, the brook flowed from left to right
 +
*2. Built walls for the bridge
 +
*3. channeled under right wall
 +
*4. I then removed floors between walls of the bridge so that walls would fall in the brook
 +
 +
Purpose of this experiment was to drain the river. I made two walls to see what happens when I drop wall on the brook tile, and when I drop walls on brook tile that has been dug out. I was expecting to see my left wall intact on the brook, like if I had built the wall right on top of brook tile. And to see my right wall intact at the bottom of the brook where I had channeled out the brook.

Setting, before removing any parts of the bridge.

When both walls fell to the bottom of brook and fell apart into blocks I had used to build the walls. This wasnt such a terrible supprice to me. What was a supprice was that those walls that had fell through walkable brook tile had "broken" the brook. Game now seems to handle those tiles like they were ending the brook. Water pours in from both ends and simply disappears.

Basically this could be used to create more tiles for water to pour out of map...

I think the image should be edited... the light blue rivers are streams, not brooks. Brooks are actually invisible on the region map, only visible on local. Only a minor issue though, but it can cause confusion. Lightning4 16:49, 16 November 2007 (EST)

2967067655

The "cave river" in seed 2967067655 is a short segment enclosed in solid rock, that comes from nowhere and "falls away" into open space at both ends - open space that doesn't extend to the level below. Is this typical of 0.27.169.33? If so, I'll have to put all my cave river plans off to a future version. Kidinnu 09:54, 14 November 2007 (EST)

That sounds very strange. The cave rivers I've seen are sourced from a "mysterious area" and usually either continue off the map or fall off the bottom. They also tend to go through several lowerings of their elevation. Are you sure you fully explored it? VengefulDonut 10:03, 14 November 2007 (EST)

I don't know where this should be mentioned, but there is a huge difference on my machine between FPS on maps with brooks and maps with rivers. I've got a 3.4ghz and 2 gig ram, and my FPS on a map with a river drops to 15-20 right off the bat, where it stays in the high 50's until 30-40 dwarves with only a brook. -- unsigned, but written by Gotthard, according to page history.

I added a bit about temporarily draining and permanently damming rivers and linked to a movie I recorded of doing just that. I think there are ways that would be easier on the dwarves and less micromanagey - one way, perhaps, may be to blast a 3-wide section of the river floor, instead of a 1-wide one, and then build floors in the middle column, and then build floodgates on top of those - that should keep the pesky backflow (which made installing the floodgates so arduous) from interfering with the damming. --SL 00:28, 30 November 2007 (EST)

Draining brooks

I made following experiment:

  • 1. Built a bridge over brook, the brook flowed from left to right
  • 2. Built walls for the bridge
  • 3. channeled under right wall
  • 4. I then removed floors between walls of the bridge so that walls would fall in the brook

Purpose of this experiment was to drain the river. I made two walls to see what happens when I drop wall on the brook tile, and when I drop walls on brook tile that has been dug out. I was expecting to see my left wall intact on the brook, like if I had built the wall right on top of brook tile. And to see my right wall intact at the bottom of the brook where I had channeled out the brook.

Setting, before removing any parts of the bridge.
