Wells with Sprinkler Use (ityopr=21)

The type 21 operating rule allows the administration date for wells with sprinklers to be different than that specified by the well water rights (*.wer) file. This operating rule is commonly applied to simulate maximum water supply mode which preferentially meets a structures demand by wells with sprinklers first, surface water second and wells with flood irrigation last. Note this operating rule expects, and checks, that the control file (*.ctl) variables itsfile, ieffmax and isprnk are set appropriately. As described in Section 4.2, the control variable itsfile provides sprinkler area, sprinkler efficiency and gwmode data; the control variable ieffmax provides flood efficiency data; and the variable isprnk specifies sprinklers will be used. Note the irrigation practice time series file (*.ipy) variable gwmode must equal 1 (maximum supply) in order for this operating rule to apply.
