SWMM - Time Series - Accumulation (Area)

A Accumulation Time Series describes the rate of accumulation of pollutants by area 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) - Item Name
  • Priority (Priority, Enum) - Information about the current state of the item. Could it be: Neutral: no problem Warning: some problem, but that does not prevent the use or calculation Critical: Some issue that prevents the item from being calculated or used
• 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:

This type of series is used in items Land Use
