Subject:   How is the  Orifice   Setting   Used  in  SWMM   5   RTC   Rules ? The Real Time Control Rule for  Orifice   Setting  can be a function of a  Setting  constant,  Setting  from a Curve,  Setting  from a PID controller and a  Setting  from a Time Series (Figure 1).    The  Setting  affects the Full Depth of the  Orifice  at each time step.  The  setting  which ranges from 0 to 1 can either completely close or open the orifice  (Figure 2).   You will have to use the equivalent in ICM or else the settings derived from the  SWMM   5  time series need to be multiplied by the  orifice  depth to have the same effect in ICM that it had in  SWMM   5 .   Figure 1.   The Possibilities for defining the  Setting  of an  Orifice  in  SWMM   5  from a...
