Regression parameters for the Rautmann drift data
Source:R/drift_parameters_focus.R
drift_parameters_focus.Rd
The parameters were extracted from Appendix B to the FOCUS surface water guidance
using the R code given in the file data_generation/drift_parameters_focus.R
installed with this package. The appendix itself is not included in the package,
as its licence is not clear.
Details
For the hinge distance, Inf
was substituted for the cases where no hinge
distance is given in the data, in this way parameters C and D are never
used for any distance if A and B are used for the case that the distance
is smaller than the hinge distance.
