View source for Hydrological attributes of buildings (Water Overlay)

Besides the [[building]]s which directly influence the hydrologic model as a [[Hydraulic structures (Water Overlay)|hydraulic structure]], each construction may also have attributes which can contribute to the hydrological model in some way. These attributes are stored and used on a grid cell level. This is different from the hydraulic structure attributes, which are stored and used on an object level. 

These attributes can be changed individually per construction or per construction's function. In most cases, these attributes already exist as a [[function values|function value]].

{{building attributes|suppresscategory=true|allowselflinks=true|
 {{:Ground infiltration md (Water Overlay)}}
 {{:Sewered (Water Overlay)}}
 {{:Water storage m2 (Water Overlay)}}
 {{:Root depth m (Water Overlay)}}
 {{:Water evaporation factor (Water Overlay)}}
 {{:Building height (Water Overlay)}}
 {{:Critical infrastructure (Water Overlay)}}
 {{:Water manning (Water Overlay)}}
 {{:Tracer ABCD (Water Overlay)}}
}}

In addition to the [[Attribute]]s of [[Building]]s affecting the calculations of the [[Water Overlay]], the [[building height (Water Overlay)|building height]] of [[Building]]s affects the interpretation of the [[elevation model (Water Overlay)|elevation model]].

|notes=
* In contrast with hydraulic structures, which can only behave as a single hydraulic object, [[building]]s can have all of the above effects on the hydrological model simultaneously.
* Attributes which are connected to a function value can not be redefined using a different attribute name.
