Introduction

The OpenSWMM Application Manual provides a series of worked-out examples that illustrate how to apply OpenSWMM to model common stormwater and drainage system scenarios. This manual complements the OpenSWMM User Manual, which explains how to use the program, and the reference manuals (OpenSWMM Hydrology Reference Manual, OpenSWMM Hydraulics Reference Manual, OpenSWMM Water Quality Reference Manual), which describe the underlying theory and numerical methods.

The examples progress from simple to more complex applications:

• Basic drainage system modeling
• Continuous simulation with climate data
• Water quality analysis
• Low impact development (LID) controls
• Combined sewer overflow analysis
• Real-time control strategies

Chapter 1 – Site Drainage Design

Content is under development. This chapter will cover the design of a basic site drainage system using OpenSWMM.

Chapter 2 – Detention Pond Design

Content is under development. This chapter will cover the design and sizing of a detention pond for flood control.

Chapter 3 – Water Quality Analysis

Content is under development. This chapter will cover pollutant buildup and washoff modeling for water quality analysis.

Chapter 4 – LID Controls

Content is under development. This chapter will cover the modeling of low impact development controls such as bio-retention cells, permeable pavement, and rain gardens.

Chapter 5 – Continuous Simulation

Content is under development. This chapter will cover long-term continuous simulation using historical climate data.

Chapter 6 – Combined Sewer Overflow Analysis

Content is under development. This chapter will cover the analysis of combined sewer overflows and the evaluation of control strategies.

Chapter 7 – Real-Time Control

Content is under development. This chapter will cover the implementation of real-time control rules for dynamic operation of drainage system elements.
