New page

By combining the output of the [[Water Overlay]]'s results on water heights, and the [[Travel Distance Overlay]], it is possible to create a calculation model for valid evacuation routes in the event of a water calamity.

| Add a [[Rainfall Overlay]].
| [[How to set linear rain and simulation time (Water Overlay)|Set the amount of rainfall of the Rainfall Overlay]] to a total of 60mm in 60 minutes, followed by 0 minutes of dry period.
| Add a [[Combo Overlay]], with the [[Rainfall Overlay]] set to input A, and a formula of "GT(AT, 0.2)". This computes all places where a route would be blocked (1) or not (0), by having more than 20cm of water stress.
| Add an [[Area]], and draw it anywhere in the [[3D world]], and with an [[Attribute]] named DESTINATION_AREA set to 1. This location will be the evacuation point.
| Add a [[Travel Distance Overlay]].
| Under "Keys", opt to use a "blocking input", and select the [[Combo Overlay]] created earlier. This will disqualify certain routes from being traversed.
| Recalculate, and play the [[Travel Distance Overlay]]
| Notice that as the simulation progresses, the green evacuation routes will be supplanted with red indications that the road is experiencing too much water stress.

|notes=
* The setup could be further expanded on by adding an additional [[Combo Overlay]] which takes into account which locations were once a valid route but later weren't, thus highlighting all the locations which become cut off from evacuation routes.
