Pit layout

Use the "Pit" button in AMWELLS graphical window dialog to start a new ANSPIT model. A dialog is displayed (shown below) that includes all of the parameters to define a new model. Tab "Create" includes pit layout, dimensions and coordinates. These parameters can also be changed using the mouse directly in the graphical window dialog.

 

 

"Layout" frame

Define pit layout in plan and profile

 "Circle"

Circular layout. Text box "Length" corresponds to the pit diameter

 "Square"

Square layout. Text box "Length" corresponds to the length of one side of the pit

 "Polygon"

Layout created by a loop of straight line segments. Quantity of segments is defined in the text box "Number of line segments". By default, all segments have the same length (text box "Length"). Shape and lengths of individual segments can be later changed using the mouse in the graphical window dialog. To do this, move the cursor to one of the polygon corners till a small circle appears. The corner can be moved to a new location using LMB

"Pit dimensions" frame


 "Length" text box

Specification of pit dimensions in plan. Choose between diameter (circular layout), side length (square layout) or segment length (polygon layout)

 "Number of line segments" text box

This field is used only for polygon layout. Minimum number: 3, Maximum number: 999

 "Depth of excavation" text box

Depth of excavation is calculated as difference between the aquifer top and the deepest point of the pit

"Center" frame

Defines the layout center coordinates, when the layout is moved or a new layout created. The center location is indicated by yellow circle in the graphical window dialog. You can move the layout by specifying new coordinates of its center and clicking "Apply" button or by moving the center using LMB in the graphical window dialog

"View" frame

Thickness and color of layout contour lines in plan and profile

"New polygon" option

Active for "Polygon" pit layout. If this option is checked, a new polygon layout is created  using inputs in frame "Pit dimensions". For unchecked option, polygon dimensions are imported from the file pitpoly.amp (if present)

"Delete pit" option

This option removes pit from the graphical window dialog. The pit can be activated again by clicking button "Apply" with unchecked option "Delete pit"

"Save" button

This button is used to save polygon layout as file *.amp. It is required only for polygon layouts

"Load" button

Loads saved polygon layout
