Well coordinates

The dialog window "Well coordinates" is used for entering coordinates of pumping and observation wells and for determining distances between wells. Entered coordinates can be used in analytical (AMWELLS) models. The dialog window also allows defining locations of hydrodynamic boundaries and calculating distances between the wells and the boundaries.

The dialog window is opened by pressing button "Coordinates" in the Editor window. The button "Coordinates" is enabled only after selection of the dialog window "Distance" (button "Distance"  in the tab "Data input").

Explanatory table

List "Pumping wells"

List of pumping wells and their coordinates (X, Y).

List "Observation wells"

List of observation wells, their coordinates (X, Y) and their distances (R) to each of the pumping wells. Distance (R) is calculated between highlighted pumping well and highlighted observation well after pressing the button "Calculate distance". When the option "Include boundary" is on, the distance (L) is calculated between highlighted observation well and the boundary.

Button "Calculate distance"

Calculates the distance between highlighted pumping and observation wells and automatically enters them in the table "Distance" of Editor. When option "Include boundary" is on, the distance (L) is calculated between the highlighted observation well and the boundary. This distance is automatically entered in the first column ("Boundary") of table "Well design" in tab "Data input".

Option "Include boundary"

This option allows to define hydrodynamic boundary location. When this option is checked, a straight line appears on the plot that can be moved by mouse cursor. When the option "Include boundary" is checked, mouse buttons are used to move hydrodynamic boundaries: the left button changes coordinates X1 and Y1, while the right button moves coordinates X2 and Y2.

The thin red line on the plot window connects the plot center and the boundary line center. For an aquifer with one hydrodynamic boundary, the wells must be located on the same side from the boundary as the red line. For an aquifer with two hydrodynamic boundaries (i.e. strip aquifer) the wells must be located between the two boundaries. If the above rules are not followed, calculations incur errors.

Frame "Boundary coordinates"

In this frame the coordinates for the start and the end of the boundary line are entered. This frame contains coordinates of the boundary, inclusion of the second boundary (i.e. "Strip aquifer" option) and the width of strip aquifer. The field "width of strip aquifer" duplicates the same field in tab "General info" of Editor.

Frame "Plot coordinates"

With the option "Auto" checked, the coordinates of the plot window corners are automatically calculated based on the entered well coordinates. With the option "Auto" unchecked, the coordinates can be entered manually: X1 – left side of the plot window, X2 – right side, Y1 – lower side, Y2 – upper side.

Button "Table"

Displays the table with coordinates of pumping and observation wells.

Option "Copy with well names"

When this option is checked, and after pressing the "Copy" button, the well names and their coordinates are copied on the clipboard. With the unchecked option only well coordinates are copied.

Button "Copy"

Copies the table with well coordinates and with well names (see Option "Copy with well names") on the clipboard

Button "Paste"

Enters well coordinates from the clipboard. The clipboard must contain only two columns (i.e. well coordinates). It is not possible to paste well names from the clipboard. Well names need to be specified earlier in the Editor (tab "General info").

Plot window

Schematic plot showing locations of pumping wells (circles) and observation wells (dots). When there are more than one well, the wells highlighted in the table appear in red colour on the plot. If several wells are located near each other, the highlighted wells appear on the top of others.

When moving mouse, cursor coordinates (in meters) are shown on the line above the plot window.

Moving mouse with pressed left button +ALT allows increase plot scale to the frame that is changing with the mouse move. Press button "x" to return to the original scale.

When the option "Include boundary" is checked, mouse buttons are used to move hydrodynamic boundaries: the left button changes coordinates X1 and Y1, while the right button moves coordinates X2 and Y2 (see option "Include boundary").

Button "R"

This option allows to measure distances in the plot window using the mouse cursor. When this option is checked, a straight line appears in the plot window. The line is moved by pressing right or left mouse buttons. Length of the line is displayed near the button "R".

Button "x"

Returns to the original scale of the plot window (see more details in "Plot window" description)

Button "="

When this option is checked, the plot window length (Y) sets equal to plot window width (X). This option is enabled only when the option "Auto" is checked.
