Results

Display all the results.

The results windows display the results of the analysis in a series of logical views.

Summary

This tab displays a summary of the network analysis and includes the outfall node data. The example below is generated for the Illudas time area method.

Flow Analysis

Display the results of the flow analysis.

This tab displays the results generated by the flow or hydraulic analysis.

The data includes:

• Link name

• Next link name

• Number of Links

• Link type

• Calculated size of the link

• Flow in m3/s

• Capacity of the link in m3/s

• Velocity at peak flow in m/s

 Overflow Analysis

Display the results of the overflow analysis.

This tab displays the results generated by the overflow analysis.

The data items include:

• Link name

• Next link name

• Inflow into the node in m3/s

• Design flow in m3/s which is the total flow from all upstream catchment areas

• Actual flow transported by the link in m3/s

• Capacity of the link in m3/s

• Overflow from the link in m3/s i.e. the difference between the design flow and the flow

• The local storage required or used at the node in m3

• The inflow storage required or used at the node in m3

Node Layout

Display the results of the node layout analysis.

The data includes:

• Node name

• Cover level of the node

• The actual cover to the incoming and outgoing links

• The depth of the manhole

Link Layout

This tab displays data relating to the geometric position of the link.

The data includes:

• Link name

• Next link name

• Number of links

• Link type

• Calculated size in mm or the link description

• Length in m

• Slope of the link expressed as a percentage

• Slope of the link expressed as a Ratio

• Inlet level of the link in m

• Outlet level of the link in m

• Cover Level of the link in m

• Cover to the link in m

• Manhole Depth in m

If the slope of a link is less than the minimum slope specified in the Link Tables, it displays in red. Similarly, if the slope is greater than the maximum slope specified in the Link Tables, it displays in blue.

Hydraulic Elevation

Display the results of the hydraulic grade analysis.

This tab displays the elevation of the hydraulic grade line, as well as other hydraulic control data.

The data includes:

• Link name

• Hydraulic grade in m

• Cover level of the node (manhole) in m

• Soffit level of the link in m

• Velocity of flow in m/s

• Flow depth in the link in m

If the link velocity is less than the minimum velocity specified in the Design Parameters, it displays in red. Similarly, if the velocity is greater than the maximum velocity specified in the Design Parameters, it displays in blue.
