having just read the devnote, specifically "Made ocean waves interact with channels properly", I had a thought, would it be possible to 'drain' an ocean into a very large fortress (a.k.a. "really big tunnel")?

[Turgid Bolk]

This would be like draining the underground river...no matter how much water you take from it, there's always more. An ocean tile is always an ocean tile. So you could fill a fortress from the ocean just as you can fill it from rivers in the current version. (It wouldn't really "drain" the ocean, as in affecting sea level, though it might be fun to try.) That's just my guess.

Actually, if you look at one of the videos, forgot which one, it actually shows the river as acting exactly like any other liquid, "losing" some as it was drained off of. Of course, it probably wouldn't be possible to affect the ocean as assuming the game handled it correctly, more water would just rush in immediately, but I don't believe there will be such thing as a "river tile" or "ocean tile" in the next game. Just squares that happen to be covered by water.

You can drain the ocean or the river and it will lose water, but it is "sourced", meaning that more water will always come in from the edge of the map to replace water that is drained off.

They'll make it snow at the beach!

That's a known bug. The only workaround is to chasm the volleyball net and build a new one out of cave spider silk. Pig tail won't work. You'll just get more beach blizzards. I had a dwarf in a fey mood once who made an iron volleyball that menaced with spikes of green glass.

The carnage was epic.

Perhaps you can pour enough water into the magma river so as to drain one of them faster than their source fills them? Sound impossible, but maybe it isn't?

I imagine that it would kill your processor before you had the chance to do any serious drainage.

ah, your right. I'll probably be too busy creating fun stuff in 3D to try this anyway.

Naw, you'd just have a permanently lowered river.

What about rewalling the edge of the map where the river and ocean come in?

I think it would have to go something like this:

1.) Start draining the water at a rate faster then it comes in.
2.) When the water comes down to the 3/7 mark your dwarves can walk through it.
3.) Rewall the edge of the map to stop water from coming in (Can you rewall in shallow water?).
4.) Continue draining until the water is all gone.
5.) From the movies it looked like water can evaporate when on the ground but I'm not quite sure.

This should drain the river or even an ocean if you're really ambitious.

[Anticheese]

I reckon that if you dig towards the river from the side and have a safty channel two tiles away from the river and keep digging these drain tunnels, then add floodgates you might be able to divert most of the river.

[Savok]

A "channel" in the update is just a trench. It can only hold 7 units of water per tile, and can thus overflow.

[Faces of Mu]

Dig a pit 15 levels below until you reach the "bottom", then dig a trench along the shoreline so that as the tide rises, it fills the trench as if deposited at the "bottom" of the world. When the tide retreats due to drainage, keep widening the trench towards the ocean.

However,

In order to out-drain the ocean, you would probably need as many drains as there are water squares or sources on the edge of the screen. I think Toady was having trouble creating these water sources when screens are meant to be seamless.
