SWMM - Time Series - Controls

A Time Series of Controls must be used with the Swmm controls, more specifically in actions, when you want to define a series of controls in the SETTING parameter

The meaning of SETTING depends on the object being controlled:

• Pumps: is a multiplier applied to the flow calculated from the curve pump speed (or relative pump speed for a TYPE5 pump)
• Orifices: is the fractional amount that the orifice is fully open ( orifice control is accomplished by lowering or raising a horizontal gate from the top of the orifice)
• Spills: is the fractional amount of the original freeboard that exists ( i.e. control of the spillway is performed by moving the crest height up or down)
• Outputs: is a multiplier applied to the flow rate calculated from the curve output nominal

This series has the following properties:

• Identification
  • Description - Use a friendly description when the item name is not enough
  • Name - name of the item
    Avoid names that are too long, or that contain the following characters: '*', '>', '<', '/', '\', '"', ':', ';', '|', '=', '`', '#', ',', '?'
• Error Evaluation
  • Priority - Information about the current state of the item. Could it be:
    • Neutral: no problem
    • Critical: Some issue that prevents the item from being calculated or used
• SWMM
  • Start Date - Date when the simulation starts
  • Start Time - Time of day the simulation starts
• Data table - the time series data, with the columns:
  • Date - the date value for multi-day simulations
  • Time - the time value on the day specified in the date (if any)
  • Value - the value to use
