Wadiso Models

Wadiso Model Characteristics/Features

• Seamless transition between modules, e.g. Graphics to Steady State to Extended Period Simulation (EPS) to Water Quality Analysis to Optimization.

• Graphical display, input and editing of any network element.

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

• All pipe data required for modeling is included in the database, with extra fields for other attributes.

• The same applies for other links, as well as for nodes and tanks.

• Graphical display of results, 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.

Model Components

The model can include pipes, tanks, pumps, and many types of control valves.

Pumps can be modeled using a parabola fit through three known points on the manufacturer-supplied or calibrated pumping curve or using a series of Heas vs Flow points.

All control valves can be simulated in fully closed, partially open (active) or fully open modes. A pump or valve can be set as closed or off by changing its current state.

Model Sizes

The Wadiso model is capable of handling 100 000+ nodes, depending on computer memory. The possibility therefore exists to build large models, including all pipes in a system, thus improving modeling accuracy. In Extended Period Time Simulation, both Wadiso and the EPANet programs can simulate more than a one week period in one-hour time increments, and also an almost unlimited number of pumps, tanks, control elements, etc.
