Network modelling

This chapter provides a brief review of principles used for creating a computer model of water distribution network behaviour. Computer modelling or network modelling (also known as network analysis) will be discussed, with different types of network analysis models covered, including steady-state, dynamic (extended period), water quality, transient, etc.

The chapter starts with an introduction to different types of models, before moving on to consider basic modelling principles, including complexity and uncertainty associated with network analysis. This is followed by the discussion of data sources for model building, focusing, in particular, on procedures for water consumption and demand assessment. The final part provides a discussion on model building for a particular purpose and the steps in model building, including model calibration and maintenance.
