Here based on the Flow rate of neck sections in combination with other parameters, the hydraulic conductivity in opposite directions was calculated. In addition, the theoretical hydraulic conductivity and flow rated were measured based on geometry of the neck.
Explanations of the evaluttion data set sheets(3_3evalutation.ods)
columns:
