	This location features a terrain elevation in the form of an internal levee, blocking water from flowing further. However, in this location a ~~cluvert~~ also exists, a pipe allowing water to flow through. Under normal circumstances this would connect water bodies to form a direct connection. However, excessive water (such as a flooding) can also flow through.		This location features a terrain elevation in the form of an internal levee, blocking water from flowing further.

	~~Flowthrough~~ is effectively only limited by the diameter of the culvert. The ~~flowthrough~~ is calculated by the [[Culvert formula (Water Overlay)\|culvert formula]].

	Applications for the Flooding Overlay include determining what locations would be impacted by a sudden flood. A large factor in what determines what evacuation routes are or aren't obstructed, or what structures are affected by flooding, is variety in elevation. The higher the terrain, the higher the water must get before it can flow across and impact construction on or behind the elevated area.		Applications for the Flooding Overlay include determining what locations would be impacted by a sudden flood. A large factor in what determines what evacuation routes are or aren't obstructed, or what structures are affected by flooding, is variety in elevation. The higher the terrain, the higher the water must get before it can flow across and impact construction on or behind the elevated area.

	At the location of the elevation popup, some subtle variety exists in the height of the terrain, causing water to flow around certain plots before enough water builds up to flow over it. This makes some locations more suitable as temporary safe locations or evacuation routes. However, strictly, the variance is so small across this area that the difference is ~~minutes~~ at best.

	After making the change, the flooding overlay will be recalculated, and the new results will indicate how water would act with the new levee. In all probability, the levee will not stop all the water permanently, but may serve to delay the water, granting more time for people to prepare or evacuate. At the top of the interface, in the [[Top bar]], find the "display" option, and select the "Original" mode. This will display the results of the original calculation. Activate the flooding overlay and find the moment in time where the water surrounds the farm. Now switch the display mode to "Planned". This will show the results of the overlay based on the effects of the levee. If the levee is effective, the new results will show the farm less (or not yet) affected by the water at the same moment in time. Forward the overlay result slightly to see the new moment where the farm is affected. All time in between is evacuation time gained by creating a levee in well-conceived location.{{clear}}		After making the change, the flooding overlay will be recalculated, and the new results will indicate how water would act with the new levee.
