List of Physical Components in InfoSewer
InfoSewerH20Map Sewer conceptualizes a sewer collection network as a collection of links connected together at their endpoints, called nodes. The nodes represent manholes, wet-wells, and outlets while the links represent pipes and pumps. The sewer system can be of any topological configuration and can … Read the rest
The Open Database Connectivity (ODBC) module of InfoSewer allows the user to actively link to any external database and import that data into the current InfoSewerH20Map Sewersession. Likewise, the user can also update an external database with InfoSewerH20Map Sewer data.
To initiate the ODBC Exchange, … Read the rest
RDII or Tri Triangular Unit Hydrograph in InfoSewer
The RDII or Rainfall Dependent Infiltration Inflow method in InfoSewer is similar to the RDII or RTK method in InfoSWMM and InfoWorks ICM, but there are some differences. The RTK data for triangles 1, 2, and 3 are defined in the Unit … Read the rest
The Colorado Urban Hydrograph Procedure in InfoSewer
The Colorado Urban Hydrograph Procedure (CUHP) uses the equations and procedures presented in the Urban Drainage Criteria Manual (USDCM) of the Urban Drainage and Flood Control District (UDFCD). Shape of the CUHP synthetic unit hydrograph is determined using the following equations that relate … Read the rest

Using InfoSewerH20Map Sewer data exchange features one can import collection system maps and the associated data created by H2OMap Sewer; export collection system maps and the associated data created by InfoSewer into H2OMAP Sewer; import/export … Read the rest
Steady State InfoSewer and H20Map Sewer
The purpose of a sanitary sewer system is to convey wastewater from various origins at various rates of flow. The maximum and minimum flow rates in a single day can vary greatly. The system should be able to carry the maximum rate of flow … Read the rest
Wet Wells in InfoSewer and H20Map Sewer
Wet-wells are nodes with storage capacity that can vary with time during an extended period simulation. The primary input properties for wet wells are:
· The bottom elevation where the wastewater level is assumed to be zero
· The minimum level, i.e., the … Read the rest
How to Make Scatter Graphs in InfoSWMM, InfoSWMM SA and H2OMap SWMM
Scatter graphs of velocity on the X axis and depth on the Y axis are important to help understand the reason for flow/depth relationships in flow surveys. You can make a scatter graph … Read the rest
Operational control rules determine how pumps and flow regulating structures (i.e., orifice and weir) in the conveyance system will be adjusted over the course of a simulation. InfoSWMM H2OMap SWMM InfoSWMM SA has the following three control classes.
· Initial Status - The initial status editor enables specification … Read the rest
Runoff Coefficients
Runoff coefficient is loosely defined as the ratio of runoff to rainfall, and is a function of watershed characteristics including land use, soil type, and slope of the watershed. The value of runoff coefficient ranges between 0.0 and 1.0. A value of 0.0 means that all of the … Read the rest
2.5 Decomposing the Corrected Flow Data
The corrected flow data can be decomposed into its DWF, GWI, and RDII flow components with the help of the rainfall data. The decomposition process is illustrated in this section.
Determining the DWF Component
The first step towards determining the DWF component of the … Read the rest
InfoSWMM and InfoSWMM SA offer 13 choices for modeling surface runoff (click on link to see more information on each method):
Example 5. Runoff Water Quality
This example demonstrates how to simulate pollutant buildup and washoff in an urban catchment. The influence of different land uses on pollutant buildup is considered and both Event Mean Concentrations (EMCs) and exponential functions are used to represent the washoff process.
Surface runoff quality is … Read the rest
