Data correction

 "Data correction" dialog box allows quick substitution of aquifer test parameters. Newly substituted data are used in current calculation and are saved only until the next loading of test project. To save the data the editor should be used. No cancel of changes is available in the dialog. To return to initial parameters load the test project once more.

 The dialog box is launched from the main menu "Analysis > Direct solution", followed by "Options" tab and "Data Correction" button.

 

"Data correction" dialog box.

 

Explanatory table

"Test" tab

Change test and aquifer parameters. Input text boxes are similar to those of the editor

"Constant rate" tab

Change the constant rate value of pumping wells. Data available from the rate table of the editor

"Distance" tab

Change horizontal distances from each pumping well to each observation well. Data available from the distance table of the editor

"Screen level" tab

Change vertical distances from each pumping well to the screen center of each observation well. Data available from the shift table of the editor. In the same place see some additional comment

"Well data" tab

Change horizontal and vertical distances to flow boundaries in area and section, length of the pumping and observation well screens, well radius. Data available from the corresponding table of the editor

"Last drawdown" tab

Change drawdown value in each observation well for the moment when the pumping was stopped. Data available from the drawdown table of the editor. For slug tests this means the initial jump /abrupt change/ of hydraulic head in the pumping well

 

For correction of observed drawdown, recovery or rate values, use the table at the left of the screen.
