GGU-DRAWDOWN: "Excavation" menu item

For rectangular excavations, enter the length and width of the excavation, and the distance of the wells from the excavation edge. Additionally, the influence of any sheet pile walls may be considered. For this, activate the "Pile wall present" check box in the following dialog box:

Here, you enter the depth of the sheet pile wall and the drawdown water level in the area of the pile wall. Using the "Show system section" menu item, you can get an overview on the position of the sheet pile wall.

For excavations bounded by polygons, you only enter the distance of the wells from the excavation edge. The shape of the excavation is defined using the "Excavation polygon" menu items, the input boxes for length and width are therefore switched off in the dialog box.
