40d Talk:Brook

Fishable?

Might be worth mentioning if brooks are normal water with respect to fishability, or whether a channel needs to be dug first. Runspotrun 16:31, 11 November 2007 (EST)

I suppose so, since it is a potential source of confusion. --Dryn 22:23, 28 November 2007 (EST)

damming

1. How do I know which side of my dam is going to be dry, before I dam a brook? (ie which way does the water flow, if the entire z-level is level, and the brook stays on the whole z-level from one edge of the screen to the other??)
2. Will it cause a flood, when I dam a brook, if I don't leave a spillway?
3. If I channel my brook so it is non-walkable, will it still freeze in winter?

1. Check the edges of the brook that meet the map, one of them will be losing water. That's the downstream side.
2. Assuming this is the same level brook, no, as the dam would be at the same level as the source.
3. Channeling will simply remove the brook floor tiles, the brook itself will still freeze, like any exposed water.

Magma vs. Brook

So I've been playing around with magma and a brook, and in addition to setting about twenty dwarves on fire, I discovered some interesting things. The first I posted to the magma article a few days ago: namely, magma coming in contact with a brook will cause the water below the brook to harden to obsidian, but does not seem to produce steam. When I dug the obsidian out, I discovered WHY: magma falls through the brook floor tiles (and onto my miners, who of course catch on fire, and go back to their barracks to "sleep it off". Yeah. That went well). This also gives the brook tile the appearance of a boulder, but it does not obstruct wagons, and if you k over it, the description is still "brook". So now I'm curious: Does water fall through the brook floor tiles as well? Once I've finished draining the brook, perhaps I'll build a water pump and find out. If so, that would mean that brook "floor tiles" act like floor grates, or possibly floor bars: that is, solid things (or solid things larger than vermin) cannot pass through, but fluids can. Which kind of makes sense. Any thoughts? Has someone already done this? --Zombiejustice 01:17, 15 June 2008 (EDT)

While the end effect might be the same I think you would find that when the magma comes in contact with the brook, some of the magma is turned to obsidian boulders by the water. The rest of the magma then falls through the boulders to the next level. The water would not become obsidian. Possibly the water is not even destroyed, just displaced... that would probably need source diving to work out. (I would guess that when a channel of magma reaches a brook tile there is infinately more water than magma - there would only be 1 x 7 units of magma but every brook tile and every aquifer tile is a gate to the elemental plane of water)GarrieIrons 02:11, 15 June 2008 (EDT)
