Introducing water quality with InfoWorks WS Pro

00:04

Info works. WS pro is capable of dynamic water quality modeling

00:08

tracking the fate of a dissolved substance in a network over time,

00:13

water quality simulation is fully integrated with

00:16

hydraulic simulation for increased speed and efficiency.

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.

00:53

If you are wanting to model the

00:54

chemical reactions between various dissolved solutes,

00:57

you will have to utilize the complex water quality module. MS

Q.

01:03

In addition to chemical transport,

01:05

the water quality model can calculate changes in the

01:07

age of water over time throughout the network.

01:11

The percentage of water reaching a node in the network

01:13

that had its origin at a specified trace node,

01:17

the dominant source providing most of the water reaching the node

01:21

and turbidity analysis which can be part of

01:24

a water quality simulation to predict discoloration events

01:28

info works. WS pro considers two transport models.

01:32

Eulerian and Lagrangian.

01:35

With the

01:35

Eulerian method, a pipe is divided into completely mixed volume segments

01:40

and transport between the elements is modeled.

01:43

Each volume segment progresses along the pipe

01:45

with non conservative substance concentration being calculated

01:50

with the Lagrangian method.

01:51

The initial and final volume segments can change size to

01:55

accommodate the segment capacity of pipes delivering and receiving flow

01:59

reactions can happen both within the bulk flow

02:02

and with the material along the pipe wall

02:06

to run the water quality module.

02:07

Both the bulk and wall reaction coefficients are required.
