9.3.5 Network Diagnostics Module
The network diagnostics module, introduced initially in Chapter 6 as NDT (network
diagnostics tool) and further upgraded for the analyses presented in Chapters 7 and 8 analyses
geometric and hydraulic properties, both in DD- and PDD mode, of a network or sequence of
networks. It further assesses the network resilience using a number of measures and puts it in
the prospective of the total costs of investment and operation and maintenance. The
calculations for single network are twofold. A selection can be made between the calculations
where detailed results will be given for one specific scenario by tabulating all the pipes, or
alternatively a particular network parameter can be modified in number of incremental steps,
defining the multipliers in similar way as it is done in EPANET with the general multiplier.
In addition to the uniform multipliers, a feature has been added to specify a range of
randomised multipliers for number of parameters. The list of options in the module is shown
in Figure 9.3.
