*********************************** Parameter Field File Specifications *********************************** The parameter field file is used to supply soil parameter information to the simulation. It is supplied as `H5 File `_. The Parameter Field Generator module always generates files compliant to this specification. The structure of this file is as follows: * H5Group: `parameters` Attributes: * array: `extensions` : n-dimensional spatial extensions of the field * bool: `millerSimilarity` : whether Miller scaling shall be used * string: `parameterization` : Only "vanGenuchten" supported * double: `variance` : Variance of the Gaussian random field for Miller scaling * H5Group: `vanGenuchten` Datasets for each parameter in a n-dimensional field. The extensions of all datasets must match. Additionally, there is the `raw_field` dataset, specifying the natural logarithm of the Miller scaling factor. * H5Dataset: `alpha` * H5Dataset: `k0` * H5Dataset: `n` * H5Dataset: `tau` * H5Dataset: `theta_r` * H5Dataset: `theta_s` * H5Dataset: `raw_field`
