CW:CityWater Project Map

Example of the Map page

The Map page displays an aerial map of the project area with the pipe network overlaying the area. This page can be reached from either the Projects page or the Project Details page using the Map tab.

Map Navigation

Map navigation similar to other mapping applications:

• To zoom in or out, use the and buttons in the top left-hand corner of the map or use the mouse scroll wheel.
• Hold the Shift key while clicking and dragging the mouse to box zoom.
• To frame the model extents on the map, use the Zoom to Extent button in the bottom right hand corner of the screen.
• The search field can be used the same as in Google Maps or Bing Maps. Addresses, landmarks, coordinates, and other search terms are acceptable. It will not find locations specific to the EPANET network such as links, nodes, or tanks.
• The Base Map drop-down menu can be used to change the underlying map to one of the following:
  • Aerial w/Label – Shows an aerial map with roads and other features labeled.
  • Aerial – Shows a simple aerial map. Roads and other features are not labeled.
  • Road – Shows a standard road map with streets labeled, but topographic features are removed.

Jump To

To zoom in on a specific node or link, the Jump to Node and Jump to Link options can be used. Enter the Label ID in the field. The field is case sensitive and the Label must be entered exactly as shown in the Label field for the node or link properties.

Map Legend

In the lower right corner, the legend is shown. The legend shows the element symbols being displayed in the map. Values shown in the legend depends on the options selected in the Layers tab on the left side of the screen. Values in the legend can be hidden by clicking on the down arrow next to the value category name.

Water Quality Options

The water quality method for the simulation run can be changed by clicking on the button. In the Water Quality Options dialog, you can change the quality method used in the simulation run. Options include: Chemical, Age, or Trace.

Example of the Water Quality Options dialog

Fire Flow Options

A peakday fire flow analysis can be performed at project upload if desired. This will create a new map layer with color-coded nodes according to the peakday fire flow available at each node based on the peakday time and residual pressure specified by the user.

From the toolbar in the map, you can get the available flow at any node in the model. This is based on the specified time step and the nozzle size chosen.

Also from the toolbar, you can select the Fire Flow Options button. This brings up the Fire Flow Options dialog where you can input a desired flow, residual pressure, and duration to generate results showing if any nodes in the zone violate this residual pressure.

Example of the Fire Flow Options dialog

Plot

When an element has been selected, CityWater can generate a plot based on the element temporal properties. Clicking the Plot button will bring up a plot on the lower half of the screen. This will display a plot of the variable versus time for the selected element. If you select multiple elements and press the Plot button, a time series for each selected element will be plotted.

Using your mouse to roll over specific plot points will bring up a dialog showing the values for the plot point.

Plots can be exported as an image. Clicking the menu button in the corner of the plot will bring up export options. Plots can be saved in PNG, JPEG, PDF, or SVG file formats.

Example of a generated plot

Animate Layers

Clicking the button will create an animation of all time steps in the simulation. This is only available if the model is not a steady-state, snapshot model.

Layers Selection

The Layers tab, in the lower left portion of the window, allows selecting which attributes to display in the map area.

There are several different layers that you can view on the map. You can toggle through the different layers using the Layer controls.

1. Select the Layers tab from the left hand panel to access e Layer controls. If the left hand panel is hidden, you can show it by using the menu button, located in the top left hand corner of the page.
2. Select Node from the Node Variable drop-down menu and Links from the Link Variable drop-down menu.

Notice how the symbology on the map and legend change. The Node and Link layers represent the network geometry with no simulation result values symbolized, which is why all the nodes and links are white.

Map layers reflect average values by default (if no specific time step is selected). While in this configuration, selecting a feature will display the average, maximum, and minimum values.

Properties

After selecting a feature, the Properties tab on the lower left side of the screen will display the values associated with the feature. The table below shows typical values displayed for each feature.

Feature	Junctions	Pipe	Pump	Reservoirs	Tank	Valves
Values	Label Type Elevation Bottom Elevation Base Demand Flow Junction Pattern Simulation Time Pressure Note	Label Link Id Start Node End Node Type Length Pipe Diameter Roughness Coefficient Pipe Minor Loss Status Simulation Time Velocity Note	Label Link Id Start Node End Node Type Head Simulation Time Note	Label Type Reservoir Head Simulation Time Note	Label Type Bottom Elevation Initial Water Level Max Water Level Nominal Diameter Simulation Time Pressure Note	Label Link Id Start Node End Node Type Valve Diameter Valve Type Setting Simulation Time Velocity Note

Add a note to any element by selecting it and pressing the Add button next to the Note property in the Properties tab on the left. Enter your note in the Add Note dialog that appears and press the Add button to save it.

The Add Note dialog

View all of the annotations on the map by going back to the Project Details page and selecting the Map tab. The annotations are listed based on element type. Use the search boxes to find specific annotations.
