Hi,
Just wondering if anyone can help with this question.. I have a 2D vertical slice model with an underground tunnel. The tunnel cuts across the slice and so is modelled as a seepage face where it intersects the slice. I have some data on groundwater inflow to the entire tunnel and am hoping to use this along with time-variant head data to calibrate my model. I know I can get time-variant fluxes out of the seepage face boundary using the budget analyser. I'm just wondering how this volume is calculated for a 2D slice model and what it really means. Does it assume the vertical slice is 1 m thick? If so then I guess I can use the budget analyser output and multiply it up for the correct length to get an estimate of the inflow to the entire tunnel...?
Thanks!
Gemma
