Recovery

Input water level recovery measurements for all wells for the times listed in the table "Time (recovery)". If  measurements were taken at different moments in different observation wells, the table "t - s" should be filled in. ANSDIMAT automatically converts the table  "t - s" to "time (drawdown)", "drawdown", "time (recovery)" and "recovery". Recovery is entered as a the difference between the water level at a specified time and the last water level measured during pumping stage. Water level measurements are input starting from zero: maximal drawdown in a well corresponds to the zero recovery value.

 

Tabbed dialog for aquifer test observation data input: recovery.

 

Explanatory table

Column "Time"

Time, automatically copied from "Time (recovery)" table. The time value is followed by the unit: d – day, h – hour, m – minute, s – second. For data processing time is converted to days

Columns with names of observation wells

Input water level recovery data. Each column corresponds to one observation well

"Insert row" button

Move recovery values for the chosen observation well one row down. The number of observation points doesn’t change so all the recovery values are shifted down by one step from the inserted row and the recovery on the last row is lost

"Delete row" button

Delete the current measured value and moves recovery values one row up for the chosen observation well. The number of observation points doesn’t change so all the recovery values are shifted up by one step from the deleted row and the recovery on the last row is blank
