BRIEF TUTORIAL ONEPANET
0RICHARD G BURCE - EDCOP
EPANET is a computer program (software) developed by the Environmental Protection Agency (EPA), U.S.A.
The software performs extended period simulation of hydraulic and water quality behavior within pressurized pipe networks.
INTRODUCTION:
1RICHARD G BURCE - EDCOP
A NETWORK consists of:
NODES: Junctions Reservoirs Tanks
LINKS: Pipes Pumps Valves
2RICHARD G BURCE - EDCOP
the flow of water in each pipe,
the pressure at each node,
the height of water in each tank,
EPANET tracks:
3RICHARD G BURCE - EDCOP
EPANET’s Modeling Capabilities :
places no limit on the size of the network that can be analyzed
computes friction headlossusing the Hazen-Williams, Darcy-Weisbach, or Chezy-Manning formula
includes minor head losses for bends, fittings, etc…

it appears at the bottom of the EPANET workspace which display the following information:
• Auto Length – indicates whether automatic computation of pipe lengths is turned on or off
• Flow Units - displays the current flow units that are in effect
• Zoom Level - displays the current zoom in level for the map (100% is full scale)
Status Bar:
8RICHARD G BURCE - EDCOP
• Run Status - a faucet icon shows:- no running water if no analysis results are available,
- running water when valid analysis results are available,- a broken faucet when analysis results are available but may be invalid because the network data have been modified.
• XY Location - displays the map coordinates of the current position of the mouse pointer.

The Network Map provides a planar schematic diagram of the objects comprising a water distribution network.
A backdrop drawing (such as a street or topographic map) can be placed behind the network map for reference. Nodes and links can be drawn at different sizes, flow direction arrows added, and object symbols, ID labels and numerical property values displayed.
Network Map:

The Data Browser (shown below) is accessed from the Data tab on the Browser window. It gives access to the various objects, by category (Junctions, Pipes, etc.) that are contained in the network being Analyzed.
Add, Delete, and Edit buttons
Selects an object category
Lists items in the selected category
Data Browser:

Map Browser
The Map Browser (shown below) is accessed from the Map tab of the Browser Window. It selects the parameters and time period that are viewed in color-coded fashion on the Network Map. It also contains controls for animating the map through time.
Sets animation speed
Selects a node variable for viewing
Selects a link variable for viewing
Selects a time period for viewingAnimates the map display over time

Property Editor:
This is used to edit the properties of network nodes, links, labels, and analysis options. It is invoked when one of these objects is selected (either on the Network Map or in the Data Browser) and double-clicked or the Browser's Edit button is clicked.
