Transient Modelling in InfoWorks TS

Transient Modelling in InfoWorks TS

This one day course is aimed at InfoWorks users who need to identify Transients in their models. The course concentrates on using the InfoWorks TS addition to InfoWorks WS. The theory behind transient analysis is discussed followed by practical examples using the software.

Transient analysis calculates the effects of sudden changes in demand, pump state and valve state changes. Methods of alleviating and controlling transients are available within the software and their affects can be evaluated through simulation.

Transient analysis settings are included in the Control for the network and are set as required on network objects. A new simulation type called InfoWorks TS has been added to the list of simulations. Setting Options in the simulation allow the user to determine the starting time of analysis and the length of the transient simulation.


This is a 1-day computer hands-on training course.

Teaching Method

Participants are guided through an introduction to the concept of transients in water mains.  Examples of the application of the program are demonstrated with the participants running the software and applying controls and testing surge alleviation methods.


A basic understanding of computers is required. Familiarity with InfoWorks WS is assumed and essential. A fundamental understanding of the operation of water distribution systems is expected.

Course Agenda

Introduction – The theory of transient cause and effect is explained. The process of transient modelling and interpretation of results and choice of transient suppression device is explored.

Practical examples – Cause and effect of transients is explored in a model. Methods of transient control are introduced and their effects are observed.
