Link to AquiferTest

In order to use the AquiferTest analysis feature, you must first have AquiferTest 2011.1 or later installed on the local machine, and specify where the program is installed in the HGA Settings on the External Programs tab.

Use this feature to analyze pumping test data in AquiferTest. For this feature, you must have one or more data queries that contains the required fields for a pumping test analysis, namely:

•Well Name

•X Co-ordinate (for both Pumping Wells and Observation Wells)

•Y Co-ordinate (for both Pumping Wells and Observation Wells)

•Pumping Start

•Pumping End

•Pumping Rate

•Observed time

•Observed depth to water level

Additional fields may also be mapped and the data sent to AquiferTest; these include:

•Well Elevation

•Screen Diameter

•Borehole Diameter

For your convenience, these fields are included in the Environmental templates, in the Well History tables.

The following section describes these settings:

Settings Tab

In the first tab, define the project units you would like to use for AquiferTest, and populate the Pumping Test information.

Pumping Wells Tab

In the Pumping Wells tab, select the data query that contains the required fields for this module, for your pumping test analysis. Then, in the grid below, map the appropriate field to each required field. If the unit for the field is defined in the database template, then the unit will be automatically populated. Otherwise, this will be left blank. If needed, you can manually enter a conversion factor, to convert the data from the HGA source, to the AquiferTest project target units.

Please Note: the AquiferTest project units for the station X and Y co-ordinates must be the same as the unit system used for the HGA project (for example, if your HGA project is using UTM, set the AquiferTest units as meters; for State Plane, set the AquiferTest units as feet). Currently, there is no conversion for these units when sending Hydro GeoAnalyst data to AquiferTest.

Pumping Rate Tab

In the Pumping Rate tab, the workflow is the same as earlier mentioned. In this tab, you must map the well name, pumping rate, and the start and end interval.

Observation Wells Tab

In the Observation Wells tab, the workflow is the same as earlier mentioned. In this tab, you must map the well name, X,Y coordinate, and the observation date/time and observed depth to water level.

Once all the required fields are defined, click the Analyze button to send the data to AquiferTest. For more details on how to use AquiferTest, please refer to the AquiferTest help documentation.
