Sewsan User Interface

Sewsan features characteristics that provide for easy, informative use. These include:

• Modeless, user friendly interface

• Seamless transition between modules, e.g. Graphics to Analysis to Tabular Results

• Graphical display, input and editing of any network element

• Non network data may also be displayed as background, e.g. parcel and street layouts

• Data for all entities required for modeling (pipes, rising mains, manholes, pumps etc) is included in the database, with extra fields for other attributes

• Graphical display of results and data, through color coding, arrows on pipes, different line thickness, different node sizes, etc., is available

• Graphical display is always geographically correct, and not schematic.

• Bitmap images can also be imported as backdrop.

• Detailed tabular data and result presentation with filtering capabilities

Model-CAD Interface

The Sewsan system is an analysis tool coupled to a CAD interface. All the model entities (pipes, manholes etc.) are stored in an internal database, and are displayed in a CAD drawing. Sewsan therefore consists of:

• The sewer model representing the physical components of the sewer system

• The CAD interface, used to display the modelled data and results

By using the layer functionality of the CAD environment various background drawings/images can be imported into the current drawing so that the system can be displayed against this background information. Such drawings/images include for example:

• The cadastral layout of the study area

• GIS shapefiles

• A bitmap image of the aerial photograph

• Contours of the study area

The CAD interface provides a user friendly, interactive environment for capturing system data and setting up a model. The CAD interface is used to:

• Convert a drawing of a system into a model

• Capture text from a drawing into the corresponding model parameter

• Display the system graphically

• Easily edit the topology of the system by adding, moving or deleting the entities

• Interrogate (and edit) the data and results of a model entity

• Select model entities either manually or by querying the data or results

• Edit a selection of model entities

• Perform comprehensive queries on the system data and results

• Print accurate plans of the system, including any background drawings which might be necessary
