Hello,
We are looking to model an extraction well. I have input the minimum head and discharge rate in m3/day and had planned to run the analysis over an increasing number of days so that we could assess decrease in groundwater head in the area around the well against time spent extracting. However the results show the same groundwater head levels irrespective of number of days the stage is run over (I have tried between 1 and 30 days). Is there anything else I would need to input / conditions I need to change in the model to be able to calculate a time dependent head reduction?
Kind regards,
Maddie
Dear Madeleine,
Could you please inform us what calculation type and pore pressure calculation type do you use in this project? Thank you.
As far as I understand, for time flow calculations we need to use Fully coupled flow-deformation or Transient groundwater flow (after Flow only on Initial phase). Also we need a PlaxFlow module for such kind of calculations.
Dear Maddie,
It would be easier to check your model, so in order to be able to assist you with your project and identifying the reason for the problem you experience, please submit a service request.
