GGU-2D-SSFLOW: "(Blankets) Linear" menu item (only for "leaky aquifer")

General principles on the definition of blankets can be found in the "Boundary/Individual blankets" menu item.

Using this menu item it is possible to assign a linearly variable water level above the blanket to several elements. This can be useful for example if you need to model a semi-pervious water course where the bed has been subject to colmation, that is, it has a blanket layer and displays a variable water level within the system.

After going to this menu item you click the nodes of the FEM mesh to which a variable water level is to be assigned. Press the [Return] key to then enter a start and an end water level above the blanket.

The selected elements are assigned a water level proportional to the separation of the element centres, increasing from the start water level to the end water level.
