How to See the Highest Continuity Errors Table in the Output Report Manager
In the output text report file of InfoSWMM, InfoSWMM SA and SWMM5 there is the Highest Node Continuity Error Table. The Table shows the highest 20 Nodes for percent node continuity errors and the actual continuity error … Read the rest
Storage Units in InfoSWMM and SWMM5
Storage Units are drainage system nodes that provide storage volume. Physically they could represent storage facilities as small as a catchbasin or as large as a lake. The volumetric properties of a storage unit are described by a function or table of surface area … Read the rest
Orifices in InfoSWMM and SWMM5
Orifices are used to model outlet and diversion structures in drainage systems, which are typically openings in the wall of a manhole, storage facility, or control gate. They are internally represented in InfoSWMM and InfoSWMM SA as a link connecting two nodes. An orifice can … Read the rest

Transects in SWMM5 and InfoSWMM
Transects refer to the geometric data that describe how bottom elevation varies with horizontal distance over the cross section of a natural channel or irregular-shaped conduit. The figure below displays an example of a transect for a natural channel.
Each transect must be given a … Read the rest
Custom Conduit Shape Curve in SWMM5 and InfoSWMM
This is a new curve type that is used to construct custom shape for closed conduits that cannot be reasonably defined using any of the existing shape types supported by InfoSWMM. The curve represents depth to full depth ratio on the Y-axis, … Read the rest
Weirs in SWMM5 and InfoSWMM
Weirs, like orifices, are used to model outlet and diversion structures in a drainage system. Weirs are typically located in a manhole, along the side of a channel, or within a storage unit. They are internally represented in InfoSWMM and InfoSWMM SA as a link … Read the rest
