Controls mandate the behaviour of links (pipes, pumps or valves) based on time or other conditions in a network. Simple Controls have a very simple syntax while Rule-based Controls can be much more complex. The text of each Control is displayed in the Project Tree and a context menu allows them to be edited in [...]

Controls are edited in the Control Editor which displays the text of all controls with syntax highlighting and auto-completion. Syntax is checked as the user typed and references to network objects are also checked to make sure that they exist.

Referential integrity is important. Whenever a network object refers to another object, WaterSums must ensure that the object really exists. Sometimes, when items are deleted, other items may be depending on them: for example a link will depend on a start node and an end node. Deleting the node requires that any links which depend [...]

A small example of a network with OpenStreetMap in the background. OpenStreetMap maps are available under an open licence, so WaterSums can display these maps without any extra licence fees or complexity. We satisfy the compliance requirements by including in the background map an acknowledgement of the OpenStreetMap contributors and their valuable work. CloudMade maps [...]

WaterSums uses the Proj.4 cartographic projections library internally and provides a panel for selecting from the available projections.

WaterSums can automatically generate terrain shading based on the elevations given in a network model for junctions, tanks and reservoirs. This process is experimental at the moment, but can help significantly with the visualisation of the comparative elevations and slopes in a network.

WaterSums allows the flexibility of choosing different levels of complexity for different applications. If arbitrary coordinates are to be used for locating network objects, the units of measure and extents of the network can be specified. The network layout can then be matched to a backdrop image to allow digitizing of network locations. In this [...]
