Sewsan Result Presentation

Sewsan provides for an extremely flexible query system in order to map data and results. For both nodes and links additional data can be included in user-fields. This allows for the inclusion of information pertaining to age, material and classifications etc. of pipes, present and future allocation of stand numbers etc. to nodes, over and above the normally required data defining the component.

A link and node legend is provided, in which the color coding parameters for any one of the link or node data fields can be specified. Maps can therefore be produced showing output data such as the spare capacities, flow, flow velocities etc with different color coding and different line widths.

In graphical display it is possible to turn on and off either the node display, so that only pipes are mapped, or the pipe display so that only nodes are mapped.

Text from the different fields can also be annotated to the nodes and links. Specific fields can be selectively annotated, e.g. the link number and pressure, or diameter.

Graphs

Graphs can be displayed for the results of any link or any node, for the entire time period. Graphs of the unit and user hydrographs as well as the simulated flow in any pipe or manhole can also be displayed.

The different components of the simulated flow hydrographs can also be displayed. These include:

• The total flow in the structure

• Infiltration into the system upstream of the structure

• The average flow contributed to continuous pumps upstream of the system

• The capacity of the pipe

Tabular Reports

The presentation of tabular reports is as flexible as that of mapping. Again, specific fields can be selected for both nodes and links, and range categories set, just as in the case of mapping. The difference being that for mapping, only a single field is selected and for tabular reporting all fields, or only the important fields, can be selected.

In the mapping, the line width or node size can be set to zero if a specific category of link or node should not be displayed - in the tabular reports a flag is set in a dialogue box in order to specify whether or not that specific category should appear in the report. This makes it possible, for instance, to print a report on only those pipes with spare capacities less than 30 percent.
