Build 5.2.0 (Feb 2022)

Engine Updates:

  1. Support has been added for modeling street runoff capture by inlet drains:
  • A new Street cross-section type, defined in the [STREETS] section of an input file, was added to the set of conduit cross-section shapes.
  • A new Inlet object, specified in the [INLETS] section of an input file, was added to select the type and sizing of an inlet structure that captures street runoff.
  • A new conduit property, defined in the [INLET_USAGE] section of an input file, was added to place inlets in a Street
    conduit and connect them to a sewer system node.
  • Inlet capture analysis using the HEC-22 equations or custom capture curves has been interfaced with SWMM's flow routing methods.
  • A Street Summary table that displays summary results for each Street conduit and Inlet, including peak flow depth and spread, has been added to the list of Summary Reports.

  1. A Type 5 variable speed pump that obeys the pump affinity laws relating head and flow to pump speed was added.

  2. Storage Curve options now include several pre-defined shapes (cylinders, paraboloids, cones and pyramids) whose geometry is based on analytical formulas

  3. Several new quantities, including past n-hour rainfall, were added to the properties that can appear in control rule condition clauses.

  4. Control rule condition clauses were expanded to include named variables and math expressions.

  5. A listing of the nodes with the highest flow routing non- convergence frequency was added to the Status Report. (#81)

  6. Support was added for the latest version of NOAA's Climate Data Online service where GHCN climate files can be retrieved in either US or SI units. (#72)

  7. An additional validation check was added to the user-supplied Initial Deficit value for Green-Ampt infiltration.

  8. The conversion of runon flow into an equivalent ponded depth
    for Curve Number infiltration was fixed.

  9. A new parameter was added to Rain Barrel LIDs indicating whether the rain barrel is covered or not.

  10. The effect that the Impervious Surface Fraction parameter for Permeable Pavement LID has on the pavement layer's effective permeability is now accounted for.

  11. The values of water depth in a Permeable Pavement LID written to the detailed LID report file are now expressed as inches (or mm) instead of feet.

  12. The math expression parser was modified to allow exponents to be expressions instead of just constant numerical values.

  13. The way in which average flow is computed was changed for the time-step-average reporting option. (#71)

  14. The total reporting time value used to compute several statistics in the summary results tables was corrected.

  15. Shell sort replaces insertion sort for sorting event periods.

  16. The number of open files that SWMM can access was increased to 8192. (#68)

  17. The command line executable now supports binary output files larger than 2 Gbytes.

  18. A number of new functions were added to the SWMM 5 API.
