Water and magma should have pressure based upon world map:

Aquifers should have high pressure, so if you dig into it it could rise up a few levels, or if you are in a low area, all the way to the surface.


Volcanoes should erupt, magma pipes could overflow, this could later be linked to gods and other events, ie god of magma gets angry, global magma pressure level rises, earthquake causes one volcanoe to be blocked off, raises global magma pressure a bit. Perhaps volcanoes form where magma pressure is too high.

Also magma cooling should be based on heat, so over a few years it might disapate heat, allowing little volcanoes to form (lava hardens, magma pressure breaks middle few tiles, raises, happens again).

There's a thing called the search function. If you used it, you'd find tons of little threads about this, and one huge megathread.

I still love the idea, and havent heard of it before myself.

I haven't either.

It would be nice if aquifers existed as large region-spanning bodies with their own elevation to them, so that the pressure changes depending on where you are, as in real life. Of course, this could lead to a lot of Fun and might be difficult to control, and aquifers would likely need to be placed more deeply (on average) for it to work. Somehow integrating them into the new cavern system as, say, giant underground rivers, would be nice too.

Not really.  Depends on the surrounding geology.

If anything, the current system is too fast.  Here's the best example I can find.  Look at those lines, days to years for water to flow downhill through the soil layers.

What causes springs is when you have a layer of non-porous rock that is holding back water from seeping out of the ground (say, a granite cliff that is a vertical layer of stone due to upthrust, so it has "dirt" behind it).  The water will seep downwards due to gravity, flow under the sheet of rock, and then come back up again, forming a spring.

Volcanoes should erupt, magma pipes could overflow,

I believe you can achieve this with a save game from before magma pipes refilled and using it in a later version. There was a bug raised on it somewhere :)

No, you achieved it by embarking on a bottomless pit map and have the two air layers above it (previous version only) filled with magma.

No, there was a bug awhile back where using an old map with a magma pipe could cause it to overflow continuously. Being able to pour magma on top of bottomless pits is a separate issue.

That is not a bug I remember.

Well, I'll be the first to admit that my memory can be faulty, but I'm as certain as I can be that I remember seeing a video of a player embarking on a map, landing next to the magma pipe, and immediately losing his dwarves to overflowing magma.

Well I find the idea of artesian wells a very cool one. As my hometown is itself built around a natural spring... I would have no hesitation in starting a fortress on an artesian well and naming it after my city.

And volcanoes erupting can only create FUN.

It would be great to have some kind of semi-natural fountain in the middle of your fortress, with the water carried off into a nearby stream. Especially if geyser-type things exist.
