Icon Attribute Unit Range Description Default value
Limit rain.png LIMIT_RAIN nominal value Whether rainfall can be overridden by rainfall defined in rain areas across the project area. 0 (Entire map)

0. Entire map: Only the weather's configured rainfall is used.
3. Override specified Areas: The weather's configured rainfall can be overridden by rain areas' Rain M attribute.
Dynamic rainfall defined by 101 different rain areas, which is shown in the mini-map halfway the animation. Animation is showing the last rain result

Notes

  • In the Rain/Flood event step of the Water Overlay Wizard, the area where the configured rain falls can be adjusted. By default, the configured rainfall is equal for each grid cell in the project area and defined by the selected weather. However, when the option Override specified Areas is chosen, the Rain Areas step is added to the wizard, which lets you configure how to identify the Rain Areas. Rain Areas override the weather's rainfall with their specific rainfall.
