Attribute: KWER [m/s] (element wise)

With this data type, horizontally isotropic conductivity values can be assigned to elements. The unit m/s must be used regardless of the specified time unit in the model file.

An 'F' in column 15 means that the K-value for the corresponding elements is a secured/fixed measured value, which must not be changed during iterative calibration.

In general, horizontally isotropic ratios apply by default for the K-values provided to this data type, i.e. Kx = Ky for horizontal and vertical (2D) models, and Kx = Ky and Kz = KFVH * Kx for 3D models.

The factor KFVH for the hydraulic conductivity in the Z direction is 1/10 by default, however, it can be explicitly defined as another value.
