-* A drainage is active when the Drainage value is larger than 0. In this case, the drainage always sets the ground water level to the same relative depth. The drainage value indicates the relative depth of the ground water.
+* For the type of behavior a drainage can have, see the [[Drainage (Subsidence Overlay)|drainage attribute]].
-* A drainage is passive when the Drainage value is smaller than 0. In this case, depending on which ground water level is used (high or low), the water level is additionally adjusted with the [[Hi passive drainage (Subsidence Overlay)|high]] or [[Low passive drainage (Subsidence Overlay)|low passive drainage]] value configured for the [[Subsidence Overlay]]. In this case, the actual negative value of the drainage does not matter.
