SWMM - Time Series - Volume

A Volume Time Series describes the variation of rainfall as a function of time in Rain gages

A Temperature Time Series describes the variation of temperature as a function of time

This series has the following properties:

• Identification
  • Description (Description, String) - Use a friendly description when the item name is not enough
  • Name (Name, String) - name of the item
    Avoid names that are too long, or that contain the following characters: '*', '>', '<', '/', '\', '"', ':', ';', '|', '=', '`', '#', ',', '?'
• Error Evaluation
  • Priority (Priority, Enum) - 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 - Comes from the SWMM settings
  • Start Date (StartDate, Double) - Date when the simulation starts
  • Start Time (StartTime, Double) - Time of day the simulation starts
  • End Date (EndDate, Double) - Date when the simulation ends
  • End Time (EndTime, Double) - Time of day when the simulation ends
• 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
• Time Series
  • Data Source - Source of the time series data
    Can be:
    • Arbitrary Values
      In this case, manually enter the values ??in the table
    • Rainfall Equation
      In this case, fill in the data:
      • Rainfall Equation (Equation, Equation) - The rainfall equation configured in Toolspace / Settings / Defaults / Drainage / Rainfall Equation
      • Return Period (TR, Double) - The rainfall return period in years, or the time it takes for a rainfall event of equal intensity and duration to recur
      • Rainfall Duration (RainDuration, Double) - Total duration of the rainfall to be distributed
      • Interval Duration (IntervalDuration, Double) - Duration of an interval in the time series
      • Start Date (StartRainDate, Double) - Rainfall start date
      • Start Time (StartRainTime, Double) - Rainfall start time
      • Number of Intervals (NumIntervals, Double) - Number of calculated intervals
        Rainfall Duration / Interval
      With these parameters, the data table will be automatically populated using the alternating block method

The data are entered into the table and plotted on the graph for better visualization:
