Link Results Data Fields (InfoWorks)

All results fields are displayed on the results grid and on the Link Property Sheet while viewing a replay of a simulation.

Time varying results are shown with the field name in an alternate colour on the grid. Non time varying results have the field name in the normal black type.

0

An intermediate state (neither on, nor off.) A pump can only change its state (switch on / off) at a major timestep. Therefore one scenario is that the level could pass below the switch off level and potentially even through the floor of the wet well, before the pump has an opportunity to switch off. To avoid this, the pump will enter this intermediate state (reported as a pump state of zero) until the next timestep is reached

STATUS

Surcharge State

In conduits the Surcharge State field indicates whether the flow rate in the system has exceeded the capacity of the drainage network to the extent that levels rise within manholes.

Value

Description

<1

Pipe is not surcharged. The water level is below the soffit level at both ends of the pipe.

Surcharge State is calculated as the ratio of water depth to pipe height.

1.00

Water level at the upstream and / or downstream end of the pipe is above the soffit level, and the flow is less than or equal to the pipe's full capacity.

2.00

Water level at the upstream and / or downstream end of the pipe is greater than the soffit level, and the flow is greater than the pipe's full capacity.

In Channels, surcharge state is calculated as flow depth divided by maximum depth of the channel; where the maximum depth of the channel is determined from the Channel Shape associated with the Channel.

In River Reach objects, surcharge state is calculated as flow depth divided by maximum reach depth; where maximum reach depth is the largest of the max elevation - min elevation values calculated for each section making up the reach.
