Abstract
Calibration of computer models for network analysis is a regular component of
the model building process. Re-calibration of existing models is also necessary
periodically, to reflect physical changes in the network. The process generally
first involves a series of field tests during which pressures and flows are recorded
at strategic locations in the system, usually continuously over one or more days.
This is followed by a desk exercise during which adjustments are made to the
roughness values used in modelling the system until a satisfactory match is
obtained between modelled and observed values. If no satisfactory match is
obtainable, further site checks are usually made to identify discrepancies
between the model and the real s
