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
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)

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
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
