Hydrological features (Water Overlay)

The water system can be enhanced with a number of hydrological features, which can be loaded in as areas. These hydrological features are a means to set specific hydrological properties to a large amount of grid cells at once.

Icon	Name	Category	Type	Identification Key	Presence
	Water area	Hydrological Feature	Area	WATER_LEVEL	Water Overlays
	Sewer area	Hydrological Feature	Area	SEWER_STORAGE	Water Overlays
	Breach	Hydrological Feature	Area	BREACH_HEIGHT	Flooding overlays
	Inundation area	Hydrological Feature	Area	INUNDATION_LEVEL	Water Overlays
	Aquifer	Hydrological Feature	Area	AQUIFER_KD	Groundwater overlays
	Rain area	Hydrological Feature	Area	RAIN_M	Water overlays
	Limitation area	Simulation Feature	Area	LIMIT_AREA	Water Overlays

Identification

Areas can be identified as a hydrological feature when this area has the identification attribute. This is the first attribute in the described table of attributes for each hydrological feature. They are also listed in the table above.

The identification attribute (and all other attributes used by hydrological features) can be configured as a key of the Water Overlay. Keys indicate which attribute of constructions or features is used to represent specific geographical input parameters for the calculation. This can be of use when setting up a project or template which makes use of user-provided geodata.

Notes

• Overlapping hydrological features of the same type are not allowed. Should in any location two or more hydrological features of the same type overlap, the values of one of them is used, and the values of the others are ignored.
