Variable Efficiency

  1. In the control file (*.ctl), set the variable efficiency switch (ieffmax) to 1.
  2. In the control file (*.ctl), set the annual time series file switch (itsfile) to 1 or 10. As described in the control file documentation, when the control variable itsfile is set to 10 conveyance, maximum flood, and sprinkler efficiency data provided by structure and year are used. Set the control variable ieffmax to 1 so irrigation water requirement (*.iwr) data provided for every diversion and well only structure by year is used.
  3. If not already created in support of a StateCU scenario, create an annual time series (*.ipy) file for every irrigation structure served by a diversion or wells only. The annual time series file is a primary input to the StateCU model; see the StateCU User’s Manual for information on the format and content of this file.
  4. If not already created in support of a StateCU scenario, create a monthly irrigation water requirement (*.iwr) file for every irrigation structure in the scenario. The StateMod formatted irrigation water requirement file (*.ddc) is an output from StateCU; see the StateCU User’s Manual for information on the format and content of this file.
  5. Include the annual time series file (*.ipy) and irrigation water requirement file (*.iwr) in the response file (*.rsp).
