Network Review/Fix Tool
The Network Review/Fix Tool is a comprehensive network
drawing examination and correction
application for use in constructing reliable, credible
working models ready for analysis. It offers users
complete functionality to quickly identify and automatically
correct any network topology problems (e.g., disconnected
nodes) and data flaws (e.g., duplicated pipes or
nodes) that may arise from digitizing a model or
building it using pre-existing GIS and CAD datasets.
The Tool consists of many useful applications including:
Locate Nodes in Close Proximity (Overlapping/Duplicate
Nodes)
Nodes in close proximity designate nodes that overlap
(accidentally duplicated) as shown in the figure
below. The Network Review/Fix Tool allows the user
to instantly view every node in close vicinity of
another node (based on any specified distance) and
automatically merge the identified nodes into one
where necessary.

Locate Pipe-Split Candidates
Pipe-split candidates represent separate pipe sections
that should be connected by a common node as depicted
in the figure below.
|
 |
The Network Review/Fix Tool allows the user to rapidly
locate all pipe-split candidates in the network
that are within a specified distance of their end
nodes and automatically make the connection where
appropriate.
Locate Crossing/Intersecting Pipes
Crossing pipes refer to those pipes that cross but
do not intersect at a common node as shown in the
figure below.
|
 |
The Network Review/Fix Tool allows the user to rapidly
view all crossing pipe candidates in the network
and automatically create the intersection where
necessary.
Locate Orphan Pipes
Orphan pipes are pipe sections which have no end
(terminal) nodes. The Network Review/Fix Tool allows
the user to quickly locate all the orphan pipes
in the network model and automatically add junction
nodes at their endpoints as shown in the figure
below.

Locate Superimposed/Duplicate Pipes
Duplicate pipes are superimposed/parallel pipes
that share the same curvilinear shape. The Network
Review/Fix Tool is able to rapidly identify all
duplicate pipe candidates in the network model.
The user can then determine if a parallel pipe actually
exists and, if so, re-route (redraw) the pipe in
a noticeable manner or remove/delete it from the
model if such a duplicate pipe does not actually
exist as shown in the figure below.
|
 |
Locate Disconnected Nodes
Disconnected nodes are stray nodes (i.e., are not
connected to any pipe) that are separated from the
rest of the network as shown in the figure below.
|
 |
The Network Review/Fix Tool allows the user to quickly
locate and highlight all junction nodes in the network
that are not connected to any pipe. The user can
then choose to connect those junctions to the system
or remove them.
Trace Network
The Network Trace function launches a spanning tree
to identify all pipes and nodes in the network that
can be reached from any specified location (source
node) via a connected path. The source node does
not need to be a tank or reservoir. This function
allows the user to instantly view all portions of
the network model that are disconnected from any
node as shown in the figure below. The user can
then easily determine if a hydraulic connection
actually exists and, if so, make the connection
in the model.
