Abbreviation in Name file



The Riparian Evapotranspiration package allows the user to model evapotranspiration separately for multiple plant functional groups within a single cell. Each functional plant group can have a separate transpiration flux curve.

Other Notes

Input to the RIP-ET is read from the file that has type “RIP” in the name file. All variables in datasets are read in free format if the option “FREE” is specified in the MODFLOW-2005 BASIC Package input file; otherwise, variables have 10-character fields, or are specified character field lengths.
