00:21

In the basic water quality module, a substance can be modeled in two ways

00:25

conservative and non conservative

00:29

conservative means the substance will only be affected

00:32

by the transport or flows within the network.

00:36

Non conservative means the substance will

00:38

react with the network environment such as

00:40

the pipe materials but not with other chemicals present in the water.

00:46

The concentration will decay or grow due to these reactions.

00:49

And these changes are in addition to the effects of transport.

Step-by-step Guide

InfoWorks WS Pro is capable of dynamic water quality modelling, tracking the fate of a dissolved substance in a network over time. In the basic water quality module, a substance can be modelled in two ways: conservative and non-conservative.

Note: Modelling the chemical reactions between various dissolved solutes requires use of the complex water quality module (MSQ).

A presentation slide containing details about WQ modelling and two ways a substance can be modelled.

In addition to chemical transport, the water quality model can calculate:

  1. Changes in the age of water over time throughout the network
  2. The percentage of water reaching a network node that had its origin at a specified ‘trace node’
  3. The dominant source of water reaching the node
  4. Turbidity analysis, used to predict discoloration events

InfoWorks WS Pro considers two transport models: Eulerian and Lagrangian.
