GGU-SLUGTEST: "At-rest groundwater" menu item
Whilst processing the at-rest groundwater level, you can take into consideration that the at-rest groundwater level fluctuates during a slug test. To make this practicable, data must be available form relatively close observation gauges.
First, enter the number of value pairs you need to enter using "x points to edit". In the list that follows this you can enter the time and corresponding groundwater level.

The individual values are then connected to a polygon. The program automatically takes these changes in the at-rest groundwater level into consideration when evaluating the slug test.
