GGU-DRAWDOWN: "Influence area" menu item

Using this menu item the drawdown range, as a function of drawdown time (days), is calculated.

You can choose from two calculation methods. The effective pore space and the time must be given for both calculation types. The differences are as follows:

  • Max. drawdown:
    Influence area as a function of the tolerable drawdown at the cone edge.

  • Lateral inflow:
    Influence area as a function of groundwater ingress at the cone edge in [%] of Qbeh.
