Wanda is an advanced, interactive software package to support the hydraulic design process of your pipeline system. The program is used for the hydraulic analysis of steady and unsteady flow conditions in arbitrary configured pipeline networks. Primary subjects to evaluate and optimise a hydraulic design are flow capacity, velocity, flow distribution, dynamic behaviour, economy, safety and control principles. With a hydraulic design, you can direct the mechanical and process engineering to an effective and efficient system.

Wanda can be applied to a variety of types of pipeline systems, like fire fighting systems, sewer systems, water distribution networks, industrial plants, oil pipelines, water cooling systems, hydropower plants and transportation systems for chemical products.

This site provides information on how to use Wanda, it also contains a FAQ and How-To section. For more information on how to buy Wanda please visit the main Deltares website or contact us at software@deltares.nl
