Adjust TransfoParam_GR5H (X2)
There might be an issue with the transformation of X2 in GR5H.
The transformation of X2 (from T to R) in
ParamOut[, 2] <- sinh(ParamIn[, 2])
For both models, the calculation of potential intercatchment semi-exchange is:
X2 is in mm/timestep, which means that X2 is timestep dependant. The calculation of hourly potential intercatchment semi-exchange is calculated differently by Le Moine, 2008, p. 173.
Most X2 values were equal to -0.04 mm/h, which is one of the prefiltering values.
