40d:Floodgate

A floodgate is an object used to regulate the flow of fluids, such as water and magma. A wood, stone or metal floodgate will suffice for water flow, but only magma-safe materials with a melting point higher than about 1200°C, such as steel, will hold back magma. Floodgates function much like doors with the 'Forbidden' option set at all times.

Floodgates can be linked to levers or pressure plates to allow them to be opened and closed remotely. An open floodgate also can be walked through, whereas a closed one can not.

For example, a water floodgate could be opened to create a shallow pool, which could be drained or allowed to evaporate. The resulting mud can be used for underground farms. Standing water could be used for drinking, or rushing water used as a defense against invaders. If there is no roof above a floodgate, and water comes to it from a source with higher elevation, the water can spill over it.

If a magma floodgate is opened, the magma will flow over it and melt any non-magma-safe mechanism, thus breaking the open/close trigger. Using magma-safe bauxite or raw adamantine mechanisms will prevent this from happening.
