Solids Builder - SWMM Nodes - Divider

Flow dividers are nodes in the drainage system that divert incoming flows to a specific conduit in a prescribed manner.

When you want to define a device as a Divider, you must add the tool Divider to the Constructor.

When adding the tool Divider, fill in your properties, in the tool's properties frame:

In the Constructor, the following properties must be filled in:

• Identification
  • Name - name of the activity
    The point name must follow the naming rules
  • Description - when the name of the activity is not enough to give context to the activity, use the description field
• SWMM
  • Flooded Area - Area occupied by flooding at the top of the junction after flooding occurs
    See: SWMM Settings / General Options / Allow Flooding
  • Diversion - link that receives the diverted stream
  • Bottom Elevation - Elevation of the bottom of the node (radier elevation)
    Must be associated with the property of the constructor that manages the device's Sump Elevation
  • Initial Depth - Initial depth of water in the storage unit at the start of the simulation
  • Maximum Depth - Maximum depth of the storage unit
  • Depth Overload - Additional water depth beyond the maximum allowable depth before the junction floods
• Divider Type
  • Divider Type - Stream Divider type
    There are four types of flow dividers, defined by how the inputs are diverted:
    1. Cut - diverts all inflow above a defined cutoff value
       In this case, provide: Flow - Cut Flow
    2. Overflow - diverts all inflow above the flow capacity of the non-bypassed conduit
    3. Tabular - Uses a table that expresses the diverted flow as a function of the total input
       In this case, provide: Diversion Curve - Skip curve used with a tabular Divider
    4. Weir - treats bypass flow as linearly proportional to inflow above a defined cutoff value
       In this case, provide: Flow - Cut Flow
  • Maximum Height - Vertical height of the Weir opening
  • Weir Coefficient - Product of the Weir discharge coefficient and its length.
    Weir coefficients are normally in the range of 2.65 to 3.10 per foot for CFS flows
