GGU-SLUGTEST: "(Hvorslev) - preferences" menu item

If you want to evaluate using the HVORSLEV method, you must first select an evaluation equation after HVORSLEV to suit your problem. In the dialog box which then opens, you are presented with the well configurations. The variable head method after HVORSLEV is implemented in the program.

Case A applies to a perfect well in a free aquifer. Case B applies to a perfect well in a confined aquifer.

In addition, you can enter a value to represent the ratio of horizontal to vertical permeability. Internally, the program uses the root of this ratio. This allows due consideration of anisotropy.

After confirming your input with "OK" you will be automatically presented with the data and best-fit curves after HVORSLEV.
