Subject:    How to  Approximate  a  Timer  in the  RTC   Rules  of  SWMM   5 SWMM   5  does not have a explicit  timer  in its Real Time Control ( RTC )  rules  but you can  approximate  it by using a Control Curve as in the attached example model.  The Control Curve will modify the setting of the Weir by the Inflow to the Storage node.  You can have normal weir flow settings based on the invert elevation of the weir and the Surface node water surface elevation but in addition you can control the weir setting by: 1.    Closing the weir when the inflow is low, 2.    Closing the weir by staggered Storage node depth, 3.    Opening the weir gradually when the inflow increases 4.    Closing the weir by a combination of Node Depth IF statements and Control Curve  rules For example, you can have the Weir Setting...
