The word "inflow" is used in two ways in sewer modeling. It is used first to describe wet weather flows to sewer systems that do not infiltrate through the ground and it is used in Bentley SewerCAD CONNECTto describe any flow which enters a node element whether it is a fixed inflow, hydrograph or pattern load. The type of load available depends on the element type. The descriptions below, refer to the Bentley SewerCAD definition of inflow.

Inflows can be specified at any node element except a pond outlet and an outfall. Inflows are not a single value but are a collection (i.e. a table of flow vs. time) and as such must be specified from Property Editor for an element. For more information, see "Defining Inflow Collections" .

Inflow hydrographs are hydrographs with flow units and are not unit hydrographs. For more information, see What is the Difference Between a User Defined Unit Hydrograph and a Hydrograph Entered in the Inflow Collection Editor.
