In VO-SWMM, five types of patterns are supported:

  • Monthly: the pattern is defined for the whole year, i.e., Jan, Feb, … Dec
  • Daily: the pattern is defined for the whole week, i.e., Mon, Tue, … Sun
  • Hourly: the pattern is defined for everyday with a time step of 1 hour, i.e. 12 am, 1 am, …, 11 pm (Note: if a Weekend pattern is used, the pattern on the weekend days will follow the Weekend pattern instead of Hourly pattern)
  • Weekend: the pattern is defined for weekend days with a time step of 1 hour, i.e. 12 am, 1 am, …, 11 pm
  • Minute5: the pattern is defined for everyday with a time step of 5 min, i.e. 12 am, 12:05 am, …, 11:55 pm (Note: the 5 min pattern cannot be used in a combination with other patterns. If one 5 min pattern is used in the Inflow Editor at a node, other pattern fields should be kept empty in the Inflow Editor)
