Walledwar - 221 Early Spring by cephalo

Map Description:

Walledwar is the new mountainhome for the Dagger of Crowns, a dwarven civilization.

Point of Interest: The Octopump

The Octopump is named for the eight fountain columns in the Great Hall. It is the result of much trial and error and several difficult problems had to be overcome. At first, an attempt was made to drive the eight fountain columns with a single pump. However, only the column closest to the pump would ever overflow into the hall due to certain mysterious physical laws. It became clear that each column would need its own pump to get them all going at once. This presented a new problem however. The standard dwarven pump can really take in a lot of water. So much so that eight pumps working directly from the river would certainly dry it out. The solution was to use only one pump drawing from the river and expelling into a holding tank that served as a source for two pumps, which expelled into another tank serving four pumps, which in turn fed the eight. So the ‘Octopump’ is actually a series of 15 pumps driving the eight fountains.

Another problem that needed to be solved was the issue of mud splashing all over the Great Hall. If the drainage area below the fountain fills up to capacity, any additional water landing on top will move laterally and create large swaths of mud. If you wish to create a mud free fountain, the drainage area must fall two Z-levels below your floor.

Wow, that river has got to be the coolest cave river I've ever seen. I take it you built it yourself? Toady needs to have cave rivers more like this, with all its windy, multilevel goodness.

I love it! It feels more organic and alive than some of those megaproject forts.

Where does that river drain to? Do you have a chasm hidden somewhere down there?

Submitted by: cephalo - 2009-03-05 to 221 Early Spring

It drains back into it's original drain at the corner of the map. It's a little 5 by 5 hole that goes through the bottom.

Could you go into more detail about how you engineered the underground forest? I see that you would have had to flood it at one point...howd you get it to flood exactly as much as you needed then back off?

I'm guessing, because of the line of wall at the end of the river, just before the drain, that he had floodgates installed in the riverbed beneath it, and possibly other floodgates at the end to keep water out while the excess drained. This river has inspired me to attempt something similar, very good job.

Yes there are floodgates at each change in z-level used for flooding. I adding a new point of interest for the control room.

You... threw adamantine... in the magma? What a waste...

Awesome fort however. I like that cave river you've made.

About the throwing of adamantine thrones in the magma:

It's all about role-play. It's a only a waste if you can't imagine the grandeur of a king under the mountain.

One can clearly see how much effort and dedication (love? ;) ) went into this.

Great job

I really love the fortress. The cave river and tower cap forest are both amazing.

Submitted by: Coaldiamond - 2009-11-13 to 221 Early Spring

Fav'd. A beautiful fortress.
