Introduction to Hydraulic Network Modelling with SWMM

SWMM allows for the hydrodynamic simulation of flows and water levels in urban storm drainage and wastewater collection networks, providing reliable information about the network functionality under a variety of boundary conditions. The hydrodynamic simulations can be extended with pollution and water quality simulations, and the model can also be enhanced by a variety of real-time control functions.

This chapter provides a comprehensive guide for the preparation of basic SWMM hydrodynamic simulation models.

The modelling process consists of the following distinct steps:

• Definition of network data
• Specification of boundary conditions
• Adjustment of computation parameters and running simulations
• Result analysis.

Furthermore, an important part of successful modelling is model calibration and verification, which ensure that computed results fit well with observations.
