I don't really care about celebrity shenanigans, so don't complain to me about how Mel Brooks defies common logic.
Sorry, couldn't resist.

You could have a "brook" wall tile that acts like fortifications, wall grates and wall bars, and is filled with water. In addition, a "brook" floor tile that acts like floor grates of bars.

I dislike the idea of renormalizing the water so that a dwarf can wade into 7/7 if the tile above is empty.  Isn't it so that while a dwarf requires <4/7, a larger creature has a broader spectrum of tiles in which they can wade?  If you changed this, then keeping the creature size feature would require multi-z-level creatures who can wade through even MORE water than a single z-level-full.

Making the brook into a river with banks to allow passage seems more like an idea that all rivers should have.

It boils down to the idea that you don't want brooks, which are far more common than rivers, requiring as many calculations as rivers, and so there's that brook floor tile, which protects the flow from evaporation and allows you to walk over it.  Rivers DO require all those calculations for flow and evaporation.  You'll notice if you start with a river in your area and it's warm that downstream, the water level is MUCH lower than it is at the source on the map.

It's just setting a priority towards running smoothly as opposed to perfect accuracy.

I'm playing on a real river map this time, and I don't notice any evaporation, the river is still 7/7 at the end of the map. However the climate is moderate...

Contrary to popular belief, common sense is not that common.

Brooks are no exception.

I've started calling it Uncommon Sense.

Say I manage to dam the brook close to the beginning of the map, or I redirect it into a bottomless pit.. and I would enter the brook bed from the bottom... would the "rocks" still be there making up walls now or would there be a long empty hall with an invisbile ceiling?

too much to read with a headache so I'll just make sure this is answered... yes, the rocks are still there and you can mine them out like any other rock.  Also, even if you mine out the rock from below, you still have to channel out the top layer for a waterwheel to work since it's really just a special 'floor'.

Brooks actually are porous walls that you can walk on top of. It makes sense if you imagine they're a bunch of stones with gaps between them that allows the water to go through. If you ever drain a brook you'll find your dwarves won't walk on the bottom of it until you have your miners destroy each 'brook' space. I'm not certain if doing so removes the brook 'ceiling' or not, offhand.

While technically a completely open space would hold more water than a space filled with loose rocks, 7/7 is a lot easier to compute right now since it becomes 'static'.

Currently rivers and brooks will be shallow at one end because they're actually flowing of the map, and while this creates some lag I can attest that it doesn't produce nearly as much lag as when the entire brook/river is fluctuating depths, for instance when a bunch of pumps are removing the water and it's flowing in from both directions to fill the gap.

Exactly, and ramps/slopes filled with 4/7 could be considerd from the CPU as 'static' just as well, because it cannot be filled with more water, due to the other half of the tile to be filled by the stone/earth ramp.

Heh, somehow I missed that this thread had replies...

You could have a "brook" wall tile that acts like fortifications, wall grates and wall bars, and is filled with water. In addition, a "brook" floor tile that acts like floor grates of bars.

That's a much more concise way of stating what I was trying to say...

Ahh. In that case, I guess my idea isn't really needed then, is it?
