SEEP/W - converting radial flow/discharge to an equivalent plane flow/discharge



I would like to model an abstraction and injection well using the SEEP 2D cross-section model. The wells in real life pump at 20m3/hr. However, when I specify a total water rate of 20 m3/hr in the model, I get a lot more drawdown and mounding compared to what I observe or model using a simple analytical equation. I see there is a way to convert radial flow to an equivalent 1D flow using the axisymmetric model. Can this or an alternative equation be used to do the same for a 1D cross-section model?

Kind regards

    Hi James, it's hard to know exactly what the problem is without seeing your model. However, values such as the hydraulic conductivity, water content, and compressibility can have a significant effect in analyses such as these so I would double check those. In a 1D model, the water rate can be calculated using the graphing tools in GeoStudio. If you'd like the support team to look at your model you can email us at
