Inflows ( Catchment Area, Green Roof, Roof and or Input Hydrograph), or from an incoming Connections, to be captured and routed into a Junctions, Manhole or Stormwater Control or bypassed to another location.Inlets allow flow from
Each system can have one or more inlets with each inlet able to support multiple incoming inflows & connections.
Junction or Stormwater Control: look for the Inlets Tab within the Properties form
it is possible to specify how the incoming flow will enter the system as this will affect the time it takes the water to pass through the Stormwater Controls - SWC There are two types:
Point Inflow - The flows passing through are seen as entering at the top end of the Stormwater Controls - SWC
Lateral Inflow- The flows passing through are seen as entering along the length of the Stormwater Controls - SWC
It is possible to specify which component of a complex stormwater control that an inlet connects too. This is only available for Bioretention or Swale (with Trench on) Stormwater Controls. There are two options:
Ponding Area - The flows are seen as entering into the top of the SWC. i.e. the Ponding Area or Swale
Subsurface Area -
This is the list of incoming Inflows and Connections that are entering the given inlet.
Use the checkboxes to select which items connect to each inlet of the Stormwater Control or Junction.
This is the destination connection that any flow bypassing the inlet will be routed.
This needs to be drawn as a Bypass Connection on the Plan.
There are 5 types of Inlet capacity that can be specified:
No Restriction - The incoming flow enters the system unrestricted
Low/High Flow - Specify a low and high filters that are applied to the flow to determine how much flow enters the system
Percentage Flow - Specify a percentage of the flow that will bypass the system .
Rated by Flow - Specify Approach Flow vs Captured Flow as a table.
HEC-22 - Specify an inlet compliant with HEC-22
