Example 4. Low Impact Development in InfoSWMM and InfoSWMM SA
This example demonstrates how to model two Low Impact Development (LID) control alternatives, filter strips and infiltration trenches. The detention pond modeled in Example 3 is an example of a subdivision-scale drainage control structure. The LIDs in this example are … Read the rest
Example 3. Detention Pond Design in InfoSWMM and InfoSWMM SA
This example illustrates how to define, design, and evaluate a detention pond using InfoSWMM H2OMap SWMM InfoSWMM SA. Storage units, orifices and weirs will be used to model a multi-purpose detention pond built to detain a water quality capture volume … Read the rest
Example 5. Runoff Water Quality in InfoSWMM and InfoSWMM SA
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 … Read the rest
InfoSWMM H2OMap SWMM InfoSWMM SA offers 12 choices for modeling surface runoff (click on link to see more information on each method):
San Diego Modified Rational Formula in InfoSWMM and InfoSWMM SA
The Rational method is a widely used technique for estimation of peak flows from urban and rural drainage basins (Maidment 1993; Mays 2001). Mathematically, the Rational formula is expressed as:
where Q = peak runoff rate (flow unit)
C = … Read the rest
Example 1. Post-Development Runoff in InfoSWMM and InfoSWMM SA
This first example demonstrates how to construct a hydrologic model of an urban catchment and use it to compare stormwater runoff under both pre- and post-development conditions. It illustrates the process of spatially dividing a catchment into smaller computational units, called … Read the rest
Example 6. Runoff Treatment in InfoSWMM and InfoSWMM SA
This example illustrates how to model water quality treatment in the BMPs that were used in two earlier examples to control runoff from a new residential development on a 29 acre site. Treatment of total suspended solids (TSS) is applied at … Read the rest
Example 2. Surface Drainage Hydraulics in InfoSWMM and InfoSWMM SA
Example 1 showed how to construct a hydrologic model of an urban catchment that compared stormwater runoff under both pre- and post-development conditions. Hydraulic routing was not considered. This example will demonstrate how InfoSWMM’s hydraulic elements and flow routing methods … Read the rest
This example shows how to run a continuous simulation with InfoSWMM H2OMap SWMM InfoSWMM SA using a long-term rainfall record. It will analyze the performance of the drainage system and BMP detention pond for the 29 acre residential site designed in … Read the rest

Management of stormwater quality is usually performed through a combination of so-called “best management … Read the rest
Example 7. Dual Drainage Systems in InfoSWMM and InfoSWMM SA
The post-development model in Example 2 simulated simple hydraulic routing within a surface drainage system that employed open channels in the form of gutters and swales. The three hydraulic routing methods (Steady Flow, Kinematic Wave and Dynamic Wave) were introduced … Read the rest
Example 10. LID Controls in InfoSWMM and InfoSWMM SA
This example demonstrates how to model two Low Impact Development (LID) control alternatives, filter strips and infiltration trenches. The detention pond modeled in Example 3 is an example of a subdivision-scale drainage control structure. The LIDs in this example are hydrologic … Read the rest
The Force Main Network Solution allows the simulation of multiple upstream and downstream force mains entering and leaving one chamber junction during an Extended Period Dynamic Simulation or EPS solution in Sewer. All of the force mains, pumps, wet wells and force main … Read the rest
Logical expressions can be developed for use on the InfoSewerH20Map Sewer Query Builder. Functions play no role in the development of Simple Controls.
Valid InfoSewerH20Map Sewer query statements are comprised of the following items:

Like a customized report, a query report is used to selectively choose which input and output data will appear in a report. However, unlike a customized report, a query report is required to relate data from an Output Relate with output data in a report format. … Read the rest
Design in InfoSewer and H20Map Sewer
STEADY STATE DESIGN
A sanitary sewer collection system has basically two main functions: to convey the designed peak discharge and to transport solids so that deposits are kept to a minimum. It is imperative, therefore, that the sanitary sewer has adequate capacity for the … Read the rest
Manholes are junctions placed at the intersection of two or more links. Three types of manholes exist in a sewer collection system.
Unit hydrograph information could be supplied to InfoSewerH20Map Sewer Pro using the 
icon located at the operation data tab of the control center. Using this icon, the user may create a new unit hydrograph from scratch or by cloning an existing one, and may … Read the rest
An output source is nothing more than an association between InfoSewerH20Map Sewer and the output (.out) file created from a simulation run. InfoSewerH20Map Sewer refers to model runs as output sources, whether they be *active*.Steady or ScenarioX.Design, every model run is affiliated to an external output … Read the rest
InfoSewer allows you to work with both Personal Geodatabases as well as SDE Geodatabases served by enterprise ArcSDE servers.
