InfoSWMM H2OMap SWMM InfoSWMM SA offers three choices for modeling infiltration:
Horton’s Equation
This method is based on empirical observations showing that infiltration decreases exponentially from… Read the rest 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 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 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 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
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, 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
The Dynamic Wave page of the Simulation Options dialog, shown below, sets several parameters that control how the dynamic wave flow routing computations are made. These parameters have no effect for the other flow routing methods.
Contents of this simulation option dialog page are described below:… Read the rest
Why a Hot Start File important in InfoSWMM and InfoSWMM SA, SWMM5
A Hot Start File in InfoSWMM InfoSWMM SA is important as it provides initial depths, initial flows and initial settings for the hydrology and hydraulics features of the SWMM 5 engine. You have three options:
Head loss due to Transitions and Fittings (Local loss)
Whenever flow velocity changes direction or magnitude in a conduit (e.g., at fittings, bends, and other appurtenances) added turbulence is induced. The energy associated with that turbulence is eventually dissipated into heat that produces a minor head loss, or local (or … Read the rest

SWMM5 Network Export from ICM 8.5 Help File
InfoWorks ICM can export networks to SWMM5 data format.
To export to SWMM5 file:
InfoSWMM and InfoSWMM SA is a physically based, discrete-time simulation model. It employs principles of conservation of mass, energy, and momentum wherever appropriate. This section briefly describes the methods InfoSWMM and InfoSWMM SA uses to model stormwater runoff quantity … Read the rest
