or at least make it so that they don't take up 90 percent of the usable map.  What is the point of an aquifer other than to be a HUGE obnoxious obstacle? Why are so many of them generated? Come on, this is silly.

[IT 000]

Two reasons, 1 It's Fun, 2 It's realistic. Aquifers are quite common in RL. Now before you start ranting I agree that aquifers are annoying and time wasters in general. But I don't believe they should be removed from the game as some people actually do like them.

That said, they're fairly easy to mod out, open up your inorganic_stone_soil file and your inorganic_stone_layer file and remove all the [AQUIFER] tags.

[Bohandas]

What we need is an easier way of bypassing aquifers. Perhaps there could be some kind of special staircase structure.

[Vattic]

More realistic aquifers is what's really needed. The rate of flooding being one of the main things. I'm sure I've seen suggestions about this already.

[G-Flex]

We need to be able to at least sort of dam water from above, and aquifers probably shouldn't exist in as much of the map as they do.

[Vattic]

I was under the impression that aquifers were pretty wide spread in reality.

If many didn't flood so fast you could use dwarves with buckets to burst through.

Indeed. Aquifers produce insane amounts of water.

They should produce only 1 unit of water, infrequently.

[Waparius]

Personally I'd rather see drainage brought in as a thing more often. Low-drainage maps should have a constant, low-level seep of water that you have to pump away until you seal up your tunnels/dig under the water table. Rain should be a bigger issue in soil as well.

[G-Flex]

Of course, if we're talking realism, then many aquifers in DF should be even harder to deal with. How do people in real life deal with, say, a column of underground water stories high? I have no idea. DF has typical groundwater right now in the form of aquifers, but it doesn't have the type that are basically gigantic underground lakes and rivers.

Yep. There's no realistic way to deal with the aquifers in the game because they contain an infinite amount of water and release it way too fast. The various breaching methods out there are absurd hacks.

For a remotely realistic aquifer you need to keep track of soil porosity and saturation for each tile. The simplest model is for saturation to be binary (a tile is either "wet" or "dry"). When a wet and a dry tile are adjacent, there's a chance on each tick (based on their combined porosity--porosity adds reciprocally, like resistors in parallel) that water will move from the wet to the dry tile. This includes open-space tiles as long as they're adjacent in any direction to a tile of earth; open space is 100% porous, and wet whenever it contains at least 1/7 water. Since a wet soil tile is more likely to drain into dry open space than into another soil tile, you can drain groundwater realistically with ditches and sumps and such.

Obviously this is a very crude model (every tile regardless of porosity contains either 0/7 or 1/7 water, and it doesn't account for things like aboveground water pressure forcing water into the soil) but with some sensible edge conditions on the map it will produce working aquifers that do something besides be a huge pain in the ass.

this aquifer that are basically undergrounds pockets of water are usually more rare (or not) the DF kind seens to be a lot more common in RL than the aforementioned type.

It would be nice if we had an option in world generation to set aquifer frequency.

[Cyborg Fireman]

It would be nice if we had an option in world generation to set aquifer frequency.

I think that is something that can be controlled in Advanced setup.

I don't think that it can be controlled directly, independantly of other variables.

[GreatWyrmGold]

I don't think it can be controlled, period.

Hm...how do people breach aquifers IRL?
