Attribute: MULD [m²] (element-wise) (horizontal and 3D models only)

This attribute is used in the calculation of the transient recharge rates. The specified value indicates the sealed area in m² that is connected to the infiltration basin or trench. A basin can consist of several elements to which the specified area is then distributed.

The diagram illustrates the use of the MULD attribute: The roofs and other sealed surfaces of a plot of land (blue) drain their rainwater to the corresponding infiltration areas (red).
