SWMM - Nodes

SWMM contains 4 types of nodes:

1. Join - node; generic that can be: manhole, connection box, manhole mouth, wolf mouth, etc
2. Outlet - the endpoint of the network. SWMM requires the discharge point to be an outlet type.
   It could be: manhole, energy sink or even a manhole
3. Splitter - flow splitter device
   Used to control the flow leaving the node. Normally, the flow that comes out of this device, does it through one of its outputs and when When this value exceeds a certain limit, the excess is output through the secondary output
4. Storage - these are nodes in the drainage system that provide the storage volume
   Could be cisterns, reservoirs, etc

All SWMM nodes share these properties:

• Treatment - Set of treatment functions for pollutants entering the node
  Each item (SwmmTreatment) in ListSwmmTreatment has:
  • Expression (Expression, String) - Treatment expression associated with each pollutant undergoing treatment
  • Pollutant (Pollutant, ObjectId) - Name of the associated pollutant
  • Pollutant Unit (PollutUnit, Enum) - Unit of measurement for the pollutant
• Inflows
  • Inflow Direct (InflowDirectFlow, SwmmInflowDirectFlow) - Specifies a continuous source of flow entering a drainage system node
  • Direct Inflow with Pollutants (InflowDirectPolluts, ListSwmmInflowDirectPolluts) - Specifies a continuous source of flow entering a node. of the drainage system and which contains pollutants
  • Dry Weather Affluence (InflowDryWeatherFlow, SwmmInflowDryWeatherFlow) - Specifies a continuous source of dry weather flow entering a node. of the drainage system
  • Dry Weather Tributaries Containing Pollutants (InflowDryWeatherPolluts, ListSwmmInflowDryWeatherPolluts) - Specifies a continuous source of dry weather flow entering a node. of the drainage system and which contains pollutants
  • RDII Affluence (RDII, SwmmInflowRDII) - Rainfall-Dependent Infiltration/Inflow
• Reports
  • Show in Report (RptFlag, Boolean) - Adds the item to the report when Some is selected. selected in the reports settings
• SWMM
  • Background Quota (InvertElevation, Double) - Elevation of the node's background. (radier dimension)
  • Tag (Tag, String) - Optional category or classification
    Note: The TAG property can be used to store information regarding the tag. typical section of to the device, useful when importing an INP file into SOLIDOS using the command SWMMIMPORT
• Calculations
  • Depth (InvertAttr, Double) - Depth
  • Head (HydraulicAttr, Double) - Head
  • Volume (StoredAttr, Double) - Volume
  • Lateral Inflow (LateralAttr, Double) - Lateral Inflow
  • Total Inflow (TotalInflowAttr, Double) - Total Inflow
  • Flooding (FloodingAttr, Double) - Flooding
  • Pollutant (PollutantAttr, Double) - Pollutant

Note: For SWMM to recognize a SOLIDOS device as a node, this must have in the definition of its constructor, the tool corresponding to the type of node, for example, the model below, implements a manhole, which is is recognized as Junction:

Note the last item. É it is he who will define; the device as being a junction to the SWMM. Also note, that the properties of the joint that depend on the geometry/location of the device are defined in the properties of the Joining Activity:

In addition, the drainage network that will calculated using the SWMM engine must also be enabled. In the network properties, note:
