The use of analytical approach to simulating pumping wells (drawdown prediction) in some cases has a significant advantage over the numerical modelling. Read more...
In borefield design the module helps to optimise
- quantity of pumping and monitoring wells,
- pumping rates, and
- well locations and distances between wells.
AMWELLS can also be used for environmental impact assessments, as it will calculate transient drawdown at environmental receptors as their response to pumping.
Borefield layouts can be assigned either manually or automatically. Automatic set up of a borefield is based on layouts of various geometry (i.e. linear, rectangular, polygon) or their combination. Production and monitoring wells may penetrate one or several horizons with possible accounting for partial penetration. Modelling results are presented in tabular and graphical formats with 2D and 3D animation of transient aquifer piezometry if required. Module is based on windows operating system.
Workflow for modelling with AmWells
Step 1. Define conceptual scheme, boundaries, their
types and model dimensions
Step 2. Specify aquifer properties
Step 3. Input pumping and observation wells . Specify constant or variable pumping rates
Step 4. Run the model
Step 5. Plot the results. Use interactive help system to plot well hydrographs, interpolated contours or piezometric head/drawdown maps
