Overview of supported MODFLOW packages

As discussed in issue #5 , this page presents an exhaustive overview of all packages and files that RMODFLOW should be able to handle. At the moment, only MODFLOW-2005 and variants are considered, i.e. MODFLOW-NWT, MODFLOW-OWHM, MODFLOW-LGR and MODFLOW-CFP. MODFLOW-USG and MODFLOW 6 are currently out of scope. RMODFLOW uses the following functions to handle input and output for MODFLOW, where the asterix denotes the package acronym (e.g. dis, bas etc.):

• rmf_create_* creates input packages
• rmf_read_* reads input packages and model output
• rmf_write_* writes input packages to text files
• rmf_build_* creates input packages from spatial and/or tidy data. Not supported at the moment.

Legend

• x means the function is implemented
• o means work in progress/high priority
• empty means not implemented yet/low priority
• NA means not applicable
