40d:Waterfall

From Dwarf Fortress Wiki
Jump to navigation Jump to search

Waterfalls can be found often in mountains. To locate them in the region map, check for rivers that cross tall cliffs.

Waterfalls, like any other falling water, generate mist that gives your dwarves happy thoughts: "He was comforted by a lovely waterfall lately." (Mist makes dwarves happy even if it's just from water cascading down a stairway, which in real life might be more a cause for alarm.)

Waterfalls can be used to drive water through a fort with nothing but gravity power: just push it through whatever channels you desire and off the cliff side when it's done its course. Large reservoirs could probably be created by building a dam at one end.

If it's cold enough for water to freeze, the waterfall will freeze as well, forming a partial wall.

Artificial waterfall

You can engineer an indoor waterfall to take advantage of the happiness it causes. You need three z-levels to do this. On the bottom is the reservoir of water. The middle layer is the screw pump and the meeting hall where your dwarves will gather to enjoy the mist. On top is a narrow corridor that connects the pump chamber to the hole though the ceiling of the meeting hall. Under this hole is a grate that connects to the reservoir.

The pump pulls water out the reservoir and pushes it up above the meeting hall. The water falls down through the grate, back into the reservoir.

Water falls straight down without splattering; thus, if you are creating an artificial waterfall, you need not account for "splash zone" on the viewing levels.

Placing such a device is best in crowded areas, such as bridges that act as your exits, or the main hallway that all the dwarves pass through.

Such a device can be seen here in movie form: http://mkv25.net/dfma/movie-193-artificalwaterfall A few mistakes to note: Water is hitting the side of the bridges, which splashes the water around and can knock dwarves in.
