Note:
*: Equivalent pipes were once commonly
used by modelers to minimize the number of
pipes in the model. The reduced model is referred
to as equivalent model. However, the limitations
(hardware and software capacities) that made
this process necessary have been eliminated
and it is better engineering practice to avoid
using equivalent pipes, especially for water
quality modeling. The reduced (equivalent)
network model will contain equivalent pipe
diameters that do not represent actual pipes,
so there can be confusion regarding what is
real and what is equivalent. In addition,
the equivalent pipes will be different from
those in the CAD and GIS data sets, which
will make it difficult to maintain data integrity
and significantly limit data updating, transfer
and maintenance. |
