ModelTracker
A comprehensive ModelTracker makes it easy for users to organize and manage any modeling project and keep track of all changes with a list of notes or information, streamlining the entire model development and analysis process. This documentation creates a customizable knowledge base that can be organized and searched intensively by project, subject, date, reference, individual modeler, specific data changes, and more. Such enhanced knowledge management enables more effective process control, project status reporting, auditing, scheduling, planning, and team management.

Extended Fireflow Simulation
An automated Dynamic Fire Flow Manager conducts accurate batch processing of fire flow computations for all network nodes. The tool considers both magnitude and duration of the fire for various customer categories in an extended period simulation (EPS) mode, then reports any system deficiencies at record-breaking speed.

Multiple Overlap Report/Graph Windows
Multiple Report/Graph Windows lets users view/display reports and graphs for any network element (pipe, pump, tank, reservoir, valve) in your projects. It is helpful to grasp the spatial information of model results easily.

Identify Diameter Discrepancy
Tool
The Diameter Discrepancy tool helps users to easily
identify diameter changes within their water network
models. It checks individual pipe diameters and
highlights connecting pipes with diameter differences
greater than or equal to a given threshold value.
Identified pipes can be saved directly to a domain
and/or a user selection set. The tool provides a
visualization of the system connections among areas
of different pipe sizing. It can also be used to
highlight areas of less than desirable pipe size
changes. A range of options is available to apply
this identification tool selectively. The tool can
be activated via application menu: Utilities, sub-menu
Network Review/Fix and item Identify Diameter Discrepancy.

Multiple Source Trace
H2ONET Analyzer allows the user to simultaneously
trace the percent contribution of any combination
of sources (or all sources) to all junction nodes
in the distribution system. Other software offers
rudimentary source tracing capability that is limited
to a single source. H2ONET offers comprehensive
tracing functionality from unlimited number of sources.

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.

Vacuum Breaker Valve
Vacuum breaker valves are devices that allow air
to enter at that location in the system when the
pressure drops to atmospheric level. They are generally
installed at high points in a pipeline to prevent
low pressure (cavitation). When the pressure drops
to zero, the valve becomes active and will compute
the correct flow rate required to maintain atmospheric
condition.
Unidirectional Flow Identification Path
H2ONET Analyzer’s unique unidirectional
flow identification path module lets you automatically
determine the sequence of water routing from any
node to help you strategically manipulate hydrants
and valves to consistently flush your system with
clean water. This ensures that the water used in
the flush sequences remains clean. Very useful for
planning unidirectional flushing sequences for removing
non-solidified deposits using internal water velocity
in the pipes.

True Variable Speed Pump Modeling
H2ONET allows fast and accurate modeling
of variable speed pumps (a.k.a fixed pressure pumps)
which will automatically adjust their speed to maintain
any user-specified target pressures/heads anywhere
in the network. The targeted heads/pressures are
allowed to vary with time during an EPS. H2ONET
uses an exact analytical solution for variable speed
pumping that ensures excellent and unmatched convergence
characteristics. In-line booster stations can also
be modeled as VSPs.

Pressure Dependent Demand
Analysis
H2ONET Analyzer will automatically carry
out pressure-demand analysis (head-driven demand
analysis) to compute the % of demand supplied to
each node (ratio of actual demand vs specified demand).
Such an analysis can be very useful for modeling
failing systems (short or long term), to study the
effects of pressure reduction (on both demand and
leakage), and to identify all critical locations
where the system is the most sensitive and to what
extent.

of recommended physical improvements to your water
system.

drawings in only a few seconds. The program will
also automatically create the end nodes and generate
proper connectivity.
