AMWELLS >

Modeling environment

Use the Model/AMWELLS model menu to start a new AMWELLS model or to work with an existing AMWELLS model.

 

Model parameters are specified in AMWELLS window that is opened after either creating a new model (Model/AMWELLS model/New model) or loading saved model (Model/AMWELLS model/Open model).

 

You can operate AMWELLS in the following four modes:

 

1) Edit mode: this mode allows editing well data and time measurements. AMWELLS operates in this mode when you start a new model or when the modes 2-4 are disabled;

2) Observation point mode: you can enter this mode by selecting the "Value" tool () from the Toolbar menu. When the mode is on, the two perpendicular red lines appear on the graphical interface window;

 

3) Model grid mode; and

 

4) WHPA mode.

 

AMWELLS editor window displays model area, model profile, toolbar and status bar. Toolbar is to the right of the model area, and model profile is immediately below the model area.

The status bar is located at the bottom of the AMWELLS window and displays information as the cursor moves across the model. This information contains:

X, Y – cursor position when it is within the model area;

Z – cursor position when it is within the model profile;

L – cursor distance from a boundary (for bounded aquifers);

R – cursor distance from the borefield centre (indicated by a green dot on the model area); and

Xc, Yc – coordinates of the borefield centre.

 

 

Examples of AMWELLS graphical window in the Observation point mode (top) and the Model grid mode (bottom)

 

Toolbar menu

Specifies basic model parameters (i.e. dimensions, coordinates) and determines how the model is displayed. Opens dialog "Model dimensions"

Dialog prompts input of pumping and monitoring wells, their construction details, distances between wells and production rates. The assigned time-series will be used by AMWELLS to calculate transient drawdown maps and borehole hydrographs. Opens dialog "Wells and time measurements"

Selection of parameters to assign aquifer properties. Opens dialog "Model parameters"

Displays a basemap. You may click the browse button to find the correct file. Opens dialog "Picture"

Zoom allows you to magnify a selected area on the current display

View full model extent

Displays the model width and length in real-world proportions. If this tool is not checked, the model area extends over the whole plan view

The measure tool lets you measure distances on the map. Use this tool to draw a line on the map and get its length or input coordinates and calculate the distance between them. Opens dialog "Distance"

This option draws graphs for drawdown and piezometric heads at the location selected in the aquifer. Clicking this option enables the "Plot” tool that is used to draw boreholes and aquifer hydrographs. Switching to “Observation point mode

The “Plot” tool is used to draw hydrographs and piezometric head profiles. Opens dialog "Plot"

Calculates drawdown at the point selected in "Value" menu

Calculates piezometric head at the point selected in "Value" menu

Opens options to run an AMWELLS model with specified parameters, loading previously saved results and switching to “Model grid” regime. The latter regime enables several display options including color flooding, contouring and 3D animation. Opens dialog "Run of analytical model"

Searches a model cell with maximum drawdown. Click this option while holding the “Shift” key, the search will be performed for the selected time. This option is enabled in “Model grid” regime only

Searches model cell with minimum drawdown. Click this option while holding the “Shift” key, the search will be performed for the selected time. This option is enabled in “Model grid” regime only

Displays/hides the grid. The model grid is not displayed when this option is checked. This option is enabled in “Model grid” regime only

This option sets up the range of values over which colors are displayed. You may change the colors, number of intervals and the drawdown value assigned to the bounds on each intervals. This option is enabled in “Model grid” regime only. Opens dialog "Classed post map properties"

Displays a specified drawdown interval by a selected color or by a random color (double click of mouse left button). This option is enabled in “Model grid” regime only. Opens dialog "Trace"

Animation of transient variations of piezometric surface. This option is enabled in “Model grid” regime only. Opens dialog "Animation"

3-D view of AMWELLS grid and modelling results. This option is enabled in “Model grid” regime only. Opens dialog "3D view"

Creates contours (isolines) of piezometric heads based on AMWELLS modelling results. Opens dialog "Groundwater potentiometric map"

Saves the current view as a figure in the clipboard

Exports model results to a text file ( .dat) or as a figure ( .bmp)

Exit “Model grid” regime

Frame “Coordinates”

The text boxes allow selecting the location at which drawdown is calculated

X and Y – coordinates (meters);

R – distance from a production well (meters).

When you move the cursor on the text boxes “X” or “Y” and press INS, the coordinates automatically change to those of the borefield centre.

The frame is activated in "Value" menu

List

You may select a specific aquifer if you are working with a multi-layer aquifer system

Frame "Block"

Number of a model block in x and y directions for “Model grid” regime

Frame "Value"

The dialog calculates drawdown (meters) for a selected time (days from the start of production) and specified location. Field “Time” allows selecting the time for which drawdown is calculated

WHPA

Delineation of Wellhead Protection Areas. This option is disabled in “Model grid” regime

Exit

Exit AMWELLS module
