Conclusion

This tutorial introduced the combined sewer system for storm water management in GeoSWMM. It demonstrated how the system behaves for a minor and a major design storm. The key points demonstrated in this tutorial are:

  1. The objective of these hydrologic and hydraulic simulations.
  2. Network description and its elements’ (subcatchments, links and nodes) characteristics.
  3. Outline of GeoSWMM model development techniques for the study area.
  4. Review of necessary model input parameters and simulation options.
  5. Analysis of model output results.
  6. Outline of options for model file export to EPASWMM.

The next case study, Tutorial 10, will demonstrate how to run a continuous simulation with GeoSWMM using a long-term rainfall record.
