Area with a varied aquifer.

含水层aquifer is a subterranean body of rock that holds groundwater. Once exposed it will start leaking water, which can lead to a lot of Fun flooding if left unmanaged. There are two types of aquifers: light aquifer and heavy aquifer, with light aquifers being by far the most common, slower to produce water and easier to manage.

含水层aquifer是一种含地下水的地下岩石体。一旦暴露就会开始渗,如果放任不管,会引发多起有趣洪水。一共有两种含水层:轻含水层重含水层,轻含水层目前最常见,产生水更慢,也更容易管理。

Aquifer tiles produce water in any neighboring open tiles – north, south, east, west, and below – not in the tile above them, nor in any diagonally-adjacent tiles. Aquifers cannot be drained; the groundwater is limitless, with even a single isolated tile leaking water forever. However, smoothed, mined, carved staircase, or channeled aquifer tiles no longer produce water. Aquifers located in ocean biomes will produce salty water; aquifers in other biomes will produce freshwater. The frequency of aquifers differs between embark locations.

含水层图块会在任何相邻开阔图块生成水,包括东方,西方,南方,北方和下方图块,不包括上方图块,也不包括任何相邻的对角图块。含水层不会干涸;地下水是无限的,即使一个单独隔离的图块永远都在漏水。但是,打磨过的,开采过的,凿过楼梯或挖通的含水层图块不再会生成水。在海洋生态群落的含水层会产生盐水;其他生态群落的则会产生淡水。各个开局地点含水层出现频率各不相同。

If you are digging an up/down staircase in the downward direction and you hit an aquifer, the aquifer tile will be revealed as damp soil or stone and the digging job will be un-designated for that tile. If you are mining horizontally, you will similarly be warned of a "damp stone" before breaching the aquifer. If you are digging an up/down staircase in the upward direction, or a ramp, and you hit an aquifer from below, the aquifer tile will immediately start producing water in the stairwell.

如果您正在向下挖上行/下行楼梯并遇到了含水层,含水层图块会显示为潮湿的泥土或石头,并且对这一图块的标定会被取消。如果您正在水平方向上挖掘,在挖开含水层前您也会类似地收到“潮湿的石头”的警告。如果您正在向上挖上行/下行楼梯或坡道,并且从下往上遇到含水层,含水层图块会立刻在楼梯井产生水。

Light aquifers 轻含水层

Light aquifers are by far the most common (being ~19 out of every 20 aquifers), and produce water at a greatly diminished rate. As a result, they can easily be penetrated with minimal effort by digging out one level at a time and walling it off reasonably quickly. Light aquifers can be very useful for low-water applications such as slowly filling a cistern for wells, or feeding an atmospheric waterfall.

轻含水层目前是最常见的(每20个含水层约有19个),而且以一个很慢的速率生成水。因此,少量的努力就可以轻易穿过它们,只需一次挖掉一层并合理快速地把它围起来。轻含水层对于低水量使用场景非常有用,比如慢速灌满蓄水池给井使用,或者为空中瀑布补水。

An open tile will receive water from a light aquifer only if it is directly north of, south of, east of, west of, or below a tile of the aquifer. The amount of water that the open tile receives is random, on average four per month, possibly reaching as low as two or as high as six. The same amount of water is received regardless of the number of adjacent aquifer tiles.

一个开阔图块只有在含水层图块相邻的东方,西方,南方,北方或下方时才会接收到水。开阔图块接收到的水量是随机的,平均每月4单位,也可能低达2单位或高达6单位。无论相邻的含水层图块有多少个,接收的水量是相同的。

If you wish to excavate a large area within a light aquifer without painstakingly and continually walling it off, dig regular drains to an open area in a non-aquifer layer where the water can evaporate more quickly than it arrives.

如果您希望在轻含水层中挖开一个大面积区域,而不用极小心又持续地围墙,可以挖一个普通的排水渠通向一个非含水层的开阔区域,在那里水的蒸发速度比它到达的速度更快。

Unlike heavy aquifers, light aquifer tiles do not drain away water.

与重含水层不同,轻含水层图块不会消水(此处应该是与下文重含水层infinite sink for water相对,即不可充当无限消水池——译者注)。

Although digging through light aquifer tiles is not very dangerous, your dwarves will continuously cancel designations with the "damp stone" warning with each new tile uncovered. The player must therefore repeatedly re-designate light aquifer squares to get the dwarves to mine it, making it a tedious affair. There is no way to turn off this automatic cancellation without using external tools such as DFHack. Alternately, once all desired tiles are revealed from above and designated for mining, when the "damp stone" alert pauses the mining activity, simply unpause for each alert (note that the unrevealed parts of designations will still be cancelled).

虽然从轻含水层中挖过去不是很危险,您的矮人们会因每个新图块被发现时产生的“潮湿的石头”的警告而持续地取消标定。玩家因此必须重复地标定轻含水层区域来让矮人挖掘,这让事情变得很乏味。除了使用类似DFHack之类的外部工具,没有办法关闭这种自动取消机制。或者,一旦所有要挖掘的图块能从上方显露并被标定为挖掘,每当“潮湿的石头”警报暂停挖掘活动时,只需为每个警报取消暂停(注意未显露部分的标定仍然会被取消)。

Heavy aquifers 重含水层

Unlike light aquifers, heavy aquifers produce water almost immediately, effectively halting excavation at or below the aquifer level. This, in conjunction with the fact that they are often located in areas rich in loam and sand, makes it difficult to find great quantities of stone in areas with heavy aquifers, making for more challenging gameplay.

不同于轻含水层,重含水层几乎立即产生水,会迅速地终止同层或下层的挖掘。这一点,以及它们经常处于富含壤土的区域的情况,导致在重含水层区域很难找到大量的石材,使得游戏也更有挑战性。

Unmined heavy aquifer tiles also act as an infinite sink for water, just like an open map edge. A single aquifer tile can absorb any amount of pressurized water each tick, limited only by the supply. One less obvious consequence is that if an opening is made through a multi-layer aquifer, only the lowest opened layer will ever fill with water.

未挖掘的重含水层图块也充当一种无限消水池,就像开阔地图的边缘。单个含水层图块每一刻可以吸收任意多的加压的水,吸水量只取决于供给。一个比较隐秘的后果就是,如果在一个跨越多层的含水层中挖了一条道路,只有最底部挖开的那层才会充满水。

Empirically, heavy aquifers gain approximately 1/7 water every 14 ticks, though production has been observed to vary from 2-28 ticks. This rate does not appear to change significantly based on the number of adjacent aquifer tiles.

从经验上来说,重含水层每14刻获得约1/7的水,虽然观察到的产水速率从2~28刻不等。基于相邻含水层图块数量,这一速率看起来变化不明显。

Varied aquifers 多种含水层

In addition to the heavy and light types of aquifer, DF can also display "Varied aquifer" on the pre-embark screen, which means there are some tiles with light and some tiles with heavy aquifers in the embark rectangle (also note that the biomes of neighboring tiles can "spill over" into a tile, resulting in different, unannounced aquifers in those parts).

除了重型和轻型含水层,矮人要塞也会在开局前的菜单上显示“多种含水层”,表示开局区域内有些图块是轻含水层而有些是重含水层(同时注意,一些相邻的生物群落图块会“溢出”到一个图块,导致这些地方出现不同的,未说明的含水层)。

Where they are found 它们出现的地方

Aquifers appear based on the elevation of the terrain. Low elevations - particularly those near rivers and oceans - are more prone to having an aquifer present, while locations closer to mountains are much less likely, but still possible.

含水层的出现基于该地带的海拔。低海拔——尤其是那些靠近河流和海洋的——更有出现含水层的倾向,而更靠近山的则更不容易出现,但仍有可能。

Layers which can contain aquifers:

包含含水层的岩层:

<!-- Note: only layers with the [AQUIFER] token can support aquifers. Other layers can appear directly below an aquifer and will blink "damp", but they are not actually part of the aquifer - digging into them will still cause water to come from above. Please check the raws for the [AQUIFER] token before adding to this list. -->

Layers which cannot contain aquifers, despite their names suggesting otherwise:

不能包含含水层的岩层,虽然它们的名字看起来像是可以:

Working in aquifers 含水层作业

When working in aquifers, some points to keep in mind include:

当在含水层中作业时,需要牢记的几点包括:

  • Water on the tile where a worker is standing will cause job cancellations if it gets too high. A construction job (e.g. wall building) will be suspended by 2/7 depth, but a mining job will only be stopped by 4/7 depth of water.
  • 在工人所站的图块上的水如果水位太高会导致工作取消。构筑工作(如造墙)会在水深2/7时搁置,但是挖掘工作只会在水深4/7时停止。
  • Flowing water will cause parents to drop their infants, leading to job cancellations, and occasionally fun.
  • 流水会导致父母丢掉他们的婴儿,工作取消,以及偶尔的乐趣
  • Aquifers do not create water in diagonal tiles, but do create water in open tiles directly below them. Therefore, you will want to dig two z-levels below the lowest aquifer layer before continuing with your fortress.
  • 含水层不会在对角图块生成水,但确实会在相邻的下方开阔图块生成水。因此,在继续您的要塞前,您会想在最低的含水层下两格挖掘的。

Probing an aquifer 调查含水层

You can discover what layer lies below an aquifer layer by digging up/down stairs into the aquifer. This will reveal the tile below the aquifer layer, and if this is non-aquifer (for example, clay, ore or bedrock) then you know the aquifer is only 1z deep at that location. This method can only be used to determine whether the aquifer is 1 layer deep, or multiple layers deep, but this is still enough information to help plan how to penetrate it. Using a pump-based method is highly recommended for multiple layer heavy aquifers.

通过挖掘上行/下行楼梯进入含水层,您可以发现在含水层下的是什么岩层。这会揭示含水层下面的图块,并且如果这是非含水层(如,黏土,矿石或基岩)那么您就会知道此处含水层z轴仅1格深。这个方法仅限于判断含水层是一层还是多层,但这些信息足够用以规划如何穿过它。非常推荐使用基于泵机的方案应对多层重含水层。

Dealing with heavy aquifers

Going around

If your embark site is covered by multiple biomes, there is a chance the heavy aquifer is not present in every biome. In some maps this may be indicated by an outcropping of stone in a landscape otherwise composed of soil; in other maps the change in biome might be visible as a change in soil type, vegetation type or density. You might be able to dig down through a biome that doesn't have a heavy aquifer, to a Z-level below the heavy aquifer, and then (if you wish) tunnel beneath the heavy aquifer to the previously -inaccessible region.

Even if all the biomes of your site contain aquifers, they might not all be at the same Z-level, so you still might be able to dig down in one biome, reaching a Z-level beneath the aquifer in another biome.

Additionally, if your biome contains deep cliffs, for instance, in the form of a river gorge, it may be possible to build a staircase down the side of the gorge past the aquifer.

The double slit method

主条目:Double-slit method

This is one of the most commonly-used methods, due to its convenience and power. It was originally developed by QuantumMenace, and is also mentioned below under the pump method.

The hatch trick

The hatch trick is a simple method for putting one or two dwarves through a single heavy aquifer layer. (This is not to be mistaken with only working for a single layer aquifer.) You can use the trick to essentially bypass the problematic final layer of a multi-layer aquifer, allowing access to the rock layers and caverns before you've put a sealed staircase through the aquifer.

First you must dig a pair of up/down stairs into the aquifer (i.e. as in twin slit), while draining one of the tiles with a screw pump, simply build a hatch on the tile (the hatch must be built on a downstairs or up/down stairs for the trick to work). Once the hatch is constructed, with the pump still operating, designate an up/down staircase under the hatch, a miner will dig the staircase out while standing 'on top' of the hatch, he can then pass through the hatch to continue digging, the hatch will let 1-2 water through with him before closing and preventing further water from following the miner. The miner is now safely under the aquifer and can dig down to the caverns or to the map edge and establish a drain, allowing you to use the much faster drainage from below method to finish penetrating the aquifer. This can save a lot of time for multiple-layer aquifers where the final layer is sand. It is also quicker and cleaner than cave-in for single layer aquifers if you plan to extend a staircase straight down to the caverns anyway (making the drain essentially free).

The ore method

On maps where the aquifer is not held in a layer of soil, but instead is held in a sedimentary layer such as sandstone, it may be possible to tunnel down through deposits of ore such as magnetite. For this to work you have to find a spot where there is coincidentally an ore deposit on each Z-level you need to dig through. This is only possible through tiresome trial and error, or through the use of a utility like DFHack's <tt>reveal</tt>. The trial and error method can be accomplished somewhat more easily by digging up/down stairs to reveal the layer underneath them without actually digging into the underlying layer. This method is more complicated with aquifers located in layers of conglomerate, as large clusters of puddingstone will support the aquifer and thus cannot be used to provide a path through it.

The "Chicken Run" technique

In versions of the game earlier than v0.40.23, this term meant having a reasonably fast/skilled miner dig a set of up/down staircases faster than the water from the aquifer could fall down the stairs and block movement into the mining tile. With luck, a miner could breach the caverns this way, allowing the aquifer water to drain. After the addition of job priorities, this became impossible. Now, when a newly revealed damp tile cancels mining, the miner will revert to "No Job" status and will take a few dozen ticks to resume mining. In that time, the miner will walk away and the site will be flooded, making the tile below unreachable.

A limited but useful variant of this technique still exists. By digging downward staircases in the layer above the aquifer, those tiles can be revealed as damp, and thus will not trigger the mining cancellation. A sufficiently fast miner (Professional or so should do for soil layers, depending on agility) can then dig a stair in one of the tiles, and before that tile floods, channel out an adjacent tile. The channel will breach the layer below, and if that layer is also an aquifer, it will of course act as an infinite drain for water from above. This then opens the possibility of opening space to work in the upper layer.

While not a direct staircase in the original method, establishing a drain with just a pick is also possible with a dabbling miner. One can channel an aquifer tile from up to four ramps dug at the corners of the tile to be channeled, such that the channel priority is higher than the ramp-digging priority. Using this, one can establish drains into the next level of a soil aquifer, as digging progress accumulates in revealed tiles.

If you fail to mine fast enough, or if flowing water pushes your miner down the channeled ramp, the dwarf will usually walk up the stairs to safety, but it is possible that the miner might <s>drown</s> have fun. In stone aquifers, a legendary miner can manage with one attempt at channeling, and at minimum, a proficient miner can manage with four, though in the second case they'll risk drowning and can take weeks to dig the next channel to expand the drain.

Exploiting cave-ins

Conceptually this method involves removing the aquifer-bearing sand, soil or rock using channeling, and then dropping an island of dry sand, soil or clay into the resulting pond, a staircase can then be dug through the center of the resulting artificial island. This requires at least one natural dry layer, but is more flexible if two or more are available. An advantage of these methods is that they can be carried out by a single miner with no resources other than a pick.

This does not work with constructed walls since they deconstruct on cave-in.

Note: There is a bugBUG #1206 that can occasionally prevent this method from working. Collapsed layers often turn into the layer type that was dug out at the level where they land (e.g. dry loam becomes dry sand). On occasion, a dry layer collapsed into an aquifer will also transform into actual aquifer tiles (e.g. dry loam becomes water-producing sand). It is unknown what triggers this behavior, but when it occurs it will be impossible to pierce the aquifer using cave-ins.

When unmined tiles collapse into a liquid, the displaced liquid teleports to sit on top of the collapsed tiles. Thus, when plugging an aquifer, it is usually advisable to incorporate aquifer drain space into the design to dispose of the displaced water.

Cave-in example

Side view
  • Dig stairs down to the aquifer. Dig over the aquifer layer but under your "plug". You'll need a 5x5 landmass. (Slide 2)
  • Channel out the area the plug will fall into. (Slide 3)
  • Leave a single floor tile on top of the plug and dig out the outer layer of your plug. The plug should be a 3x3 landmass now. The single floor tile must keep the plug from falling. (Slide 3)
  • Channel out the floor tile holding up the plug. (Slides 4 & 5)
  • Construct floor tiles to reach the plug and dig through the middle to get under the aquifer. (Slide 6)

Concentric ring method for multiple layers

If you build many rings inside one another in your top drop layer, you can breach multi-level aquifers with as little as 2 natural layers of dry soil above it. Drop the rings from the outside to the inside using constructed arms to hold the center rings in place. Once a ring drops into the water below it, pump out the water in the center and dig down another layer. When that is complete, drop the next ring and continue the process until you are through. Since you start dropping rings from the outside it is necessary to know how many levels deep the aquifer is before you begin.<br> Tutorial for more than one Aquifier can be found here: Rhenaya/HowtoDualAquifer

"Chicken-Run" plug

This method was developed for a single-pick challenge on a hostile biome. In the specific (but common) case of a 2-Z thick soil aquifer, with two dry layers above, it is possible to very quickly penetrate the aquifer using a cave-in without breaching the surface and compromising the fort's security. The method starts with a Chicken Run (see above), after which an area of the upper aquifer level is cleared out with drainage into the lower level. The lower dry level is then collapsed, which means that the sub-surface level only needs to be mined (to release the plug) rather than collapsed as part of the plug.

The procedure is described in detail in this and the following posts.

While not yet demonstrated, it should be possible to use successive cycles of chicken-running and clearing to pierce arbitrarily deep soil aquifers this way.

The pump method

The pumping method uses one or more pumps to keep an area dry long enough to smooth or wall off the sides, stopping the flow of water. It requires no special environment or resources, other than wood and dwarves (and patience). Most commonly, a modestly-sized section of the aquifer layer is channeled out and several screw pumps are built facing it. Directly behind each of the screw pumps a few tiles are channeled out to receive and dispose of the pumped water. When the pumps are activated, they should pump water faster than the aquifer can produce it, allowing masons to smooth or build walls around your future staircase. You will get job cancellations during this process, as stray 2/7's of water interrupt the building process. Just unsuspend the construction when this happens, as long a dwarf manages to touch the wall before canceling, it will move incrementally toward completion and eventually finish. Depending on the availability of screw pumps and dwarves, you may need to wall off one corner or side at a time, then move the pumps and repeat. When drilling through more than one aquifer layer, be sure to leave yourself enough room to build additional layers of pumps and water disposal channels on lower levels.

Things to consider:

  • The smaller your work area, the less water your dwarves will have to remove and the faster construction will finish. For a single-layer soil aquifer, you only need to mine five tiles (your stairway and walls directly North, South, East, and West of it); single-layer stone aquifers require only a single tile be channeled.
  • Mechanical power may come in handy, but dwarf power works just fine and is much more portable.
  • Channels can sometimes be used in place of walls, causing water produced by the aquifer on one level to immediately fall and be consumed by the aquifer on the level below.
  • This method may take a while.

Specific pump methods in detail

QuantumMenace's double-slit method can pierce an aquifer of any depth using only wood and dwarven labor. Taken from this forum post.

Earlier in the same thread, Hans Lemurson laid out a very dwarfy method that can also pierce aquifers of any depth, using several pumps and machinery. Find it here.

A convenient method without job cancellation using a pump stack was presented by kingubu in this forum post, see Pump-stack_method

Leonidas posted a detailed procedure, copiously illustrated, for tunneling through any aquifer with limited resources and relative safety.

The freezing method

If you are playing in a freezing or very cold landscape, where it snows in winter and instantly freezes water on the map, you can dig out a 3x3 hole in the ground using channels, and make it deeper and deeper until you reach the aquifer level. Once you reach the damp rock, tunnel into it with up/down staircases, then channel out the downstairs, the exposed water will turn to ice, digging the up/downstairs before channeling allows the tiles to safely fill with 7/7 water before being frozen, this avoids the hazard of miners being encased in ice and avoids a bug(?) where frozen water which is less than 7/7 deep does not produce a floor above it. The central square of the 3x3 hole should be tunnelable ice, so you can get to the rock beneath.

If your fortress is in a zone that gets warm, build walls around the inside of the hole to stop the water coming in once the ice melts. In order to build a wall around a 1x1 staircase it will be necessary to have a 5x5 hole, since you need to leave an outer ring of ice to seal the aquifer.

If the aquifer is multiple layers deep you will need to start with a sufficiently large hole to account for both an ice wall to seal the aquifer and a constructed wall to seal the ice wall for each layer of the aquifer. A pump based method might be preferable.

As an alternative to building a second wall to seal the ice wall, you can establish a drain into the caverns, and build a constructed wall when the melt comes.

The magma/obsidian method

If you have access to a supply of magma, you can create your own obsidian caissons. By channeling into the aquifer layer and then filling these channels with magma, or by digging staircases and pouring magma down the staircases, it is possible to create a wall of obsidian between your working area and the water-bearing rock or soil. However, changes to world generation with the last version have made this method more difficult than it once was, as it is now harder to find magma vents that extend above the aquifer level.

The drainage method

Having made an initial hole in the aquifer, you may wish to punch another larger hole through, say for example to grow wild strawberries in the caverns. Or you may simply want an additional (natural stone!) staircase. Once you have access from below this is much easier than digging from above, and it has the additional benefit of producing a shaft of exactly the size you want.

Locate the caverns and dig a drainage shaft of up/down stairs or downward stairs up from the caverns to the aquifer (downward stairs function as grates and are far safer than channeling). Once the drainage shaft is complete punch the shaft up through the aquifer (using up/down stairs) until you hit dry dirt. Now mine out the walls around the shaft and build constructed walls to seal the aquifer. It's even faster if the walls are dug out using down stairs instead, constructed walls can be built on the stairs and water falls straight through, thus construction can always be started and is never suspended. Always build the walls from the highest layer down, so the dwarves aren't having water dumped on them from above.

This method can be used to create arbitrarily large (and shaped) holes. Large holes, which would be impractical to dig from above, are very easy using this technique. It's also extremely useful for digging straight shafts through "layercake" aquifers where aquifer tiles and non-aquifer tiles are intermixed.

Just be very aware that your framerate is bound to suffer, if you are not fast with plugging the aquifer walls.

The modding method

本页面包含模组,其中的内容不包括在原生的《矮人要塞》游戏中。修改游戏文件有时会导致不可预料的结果,必须小心谨慎!

By editing the raws and removing the [AQUIFER] tag from all of the appropriate entries in inorganic_stone_layer.txt, inorganic_stone_mineral.txt, and inorganic_stone_soil.txt it is possible to remove all aquifers from the world. This can be done before creating a new world or after, if you find a particularly neat location ruined only by the presence of an aquifer. In order to modify an existing world, you must delete the [AQUIFER] tag from the raws in the savegame's folder.

With Lazy Newb Pack

Using the Lazy Newb Pack you can disable aquifers in the options tab before generating a new world. This works similarly to the command-line method below, but is usually a lot easier.

With DFHack

The DFHack command <code>light-aquifers-only</code> changes all heavy aquifers to light aquifers. If you prefer not having to deal with aquifers at all, the DFHack command <code>drain-aquifer</code> removes the aquifer flag from all tiles in your current embark without requiring raw edits.

With DFHack's tiletypes command

DFHack's "tiletypes" command lets you remove the aquifer flag from specific tiles only. This is useful if you want to keep a heavy aquifer on your map, but don't want to deal with the hassle of breaching it.

To create 4x4 aquiferless shaft, do this:

  1. Type "tiletypes" in DFHack to open the tiletypes tool
  2. Type in the following commands to set the tool's filter, paint and brush settings accordingly:
    • filter any
    • paint aqua 0
    • range 4 4
  3. In Dwarf Fortress, press 'k' to bring up the cursor, and move the cursor to the position you want the top left tile of your shaft to be.
  4. In DFHack, type "run". The aquifer will be removed in a 4x4 square below and to the right of your cursor.
  5. Repeat steps 3 and 4 for every aquifer layer you have. Don't worry about hitting non-aquifer tiles, they shouldn't be affected by the tool at all.

Alternatively, in step two you can provide a third number for the range. This number will represent how many Z levels deep to remove aquifers.

If you don't know how deep your aquifer is, either use the "reveal" command in DFHack to check, or just set the tiletypes range to encompass multiple z-levels. For instance, use "range 4 4 20" and use "tiletypes-here" on a tile 20 layers below the surface of your shaft.

Command-line (Linux/OS X)

Note that this prevents light aquifers as well as heavy ones!

cd df_linux/raw/objects/
sed -i 's/\[AQUIFER\]/(AQUIFER)/g' inorganic_stone_*.txt

and generate world. To edit an already generated world, run the <code>sed</code> command in the <tt>df_linux/data/save/regionNN/raw/objects</tt> folder instead.

OS X requires an argument to the <code>-i</code> flag, which is used as an extension to create backup files (but it can be empty):

<pre>sed -i  's/\[AQUIFER\]/(AQUIFER)/g' inorganic_stone_*.txt</pre>

If you want to restore the tags later, you can do it with the command:

sed -i 's/(AQUIFER)/[AQUIFER]/g' inorganic_stone_*.txt

Text editor (all operating systems)

You can manually perform the command-line method above.

There are three files. They can be found in two different places.

For every new world you make:

   “THE FOLDER DF IS INSTALLED IN”/raw/objects

For worlds that have already been made:

   “THE FOLDER DF IS INSTALLED IN”/data/save/“THE WORLD YOU ARE EDITING”/raw/objects

The three files you are editing are:

    inorganic_stone_layer.txt
    inorganic_stone_mineral.txt
    inorganic_stone_soil.txt

Open these in a text editior. Open the “Find and Replace” function of your text editor.

Replace all instances of [AQUIFER] with (AQUIFER)

Later on, if you would like to reverse the process, replace (AQUIFER) with [AQUIFER].

Benefits of aquifers

Aquifers can be useful for building a self-sufficient fortress, and are often indispensable for water-related megaprojects in maps without a river.

Aquifers outside ocean biomes also contain fresh water. Since aquifers are almost always located close to the surface, freshwater aquifers can easily be turned into a source of infinite, secure, non-freezing drinking water for your dwarves, eliminating the need for a cistern. While both of these roles can also be filled by cavern features, an aquifer allows you to get the same advantages without exposing yourself to potentially <s>dangerous</s> Fun cavern creatures.

A benefit of heavy aquifers?

Although annoying, heavy aquifers can absorb an infinite amount of water, meaning they can function as a drain for anything above them. For instance, digging a pit in a lower Z-level of the aquifer, then connecting it to a breached aquifer a level above, through a channel dug a level above that, will create a permanently flowing, compact, secure water/power source completely contained within the fortress.

Technical implementation of the aquifer version split

The aquifer split introduced in 0.47.01 uses the crude but effective random-appearing method of making all aquifers light unless the Drainage modulo 20 equals 7.

Notes & Bugs

  • As of v0.47.01, there are two types of aquifers: light aquifer and heavy aquifer, with light aquifers being by far the most common. Prior to this, all aquifers behaved as the "heavy" type.
  • Aquifers south/west of the NW-SE diagonal in the local embark map are not displayed on the embark screen (but they're still present). BUG #11358
