GGU-2D-TRANSIENT: "Diffuse sources for soils" menu item
Individual soils can be defined as fixed diffuse sources by assigning a discharge to the respective soil (e.g. m³/s/m²). Select the soil in the dialog box and enter the value for the diffuse source.

Alternatively, the value of the diffuse source can be automatically determined by the program. If you click the button "Determine value of diffuse source from sum Q" you must enter the discharge for the area of the selected soil in the new dialog box. The program then determines the value for the diffuse source from the data given. This value can then be accepted.
