transfer rate

Hi,

If the hydraulic conductivity (K) of the river bed is known, how to determine the thickness of the colmation layer in oder to calculate the the transfer rate? Your response is appreciated.

Thanks,

1. Drill a hole.
2. If you know the cross-flow between river and aquifer or their heads, go by inverse calibration. If it results in a 200 meters colmation layer, there's something else wrong...
Good luck,

Giovanni

Hi Giovanni,
Can you explain your advices, I don't understand how I can do that,
H_river is known but I think that H_aquifer is given by Feflow or I am wrong??
Thank you.
Sana.
