In InfoWorks ICM, you create, simulate and analyze hydraulic models.
00:08
A hydraulic model is a mathematical model of a fluid flow system.
00:12
ICM uses a dynamic simulation engine to model the hydraulic behavior of a water system, such as a river or sewer network.
00:23
ICM provides insights into various aspects of a hydraulic system.
00:27
You can analyze system function, measure performance, understand behavior, and assess risk.
00:34
Outputs can be used to estimate project costs and inform funding decisions.
00:41
Engineers working with ICM can create hydraulic models, analyze environmental impacts,
00:46
or help civil engineers design structures and plan land work.
00:51
Typically, ICM is used to predict the performance or behavior of a system under current and future conditions,
00:57
which helps to answer important questions, such as:
01:02
Which properties are at risk of flooding from a severe storm?
01:05
How does a storm impact water quality?
01:08
How high does my flood embankment need to be?
01:10
Ultimately, there are economic decisions to be made.
01:14
ICM helps you and other stakeholders comprehend the complexity and scale of the problem,
01:19
and to understand the risk and cost associated with proposed solutions.
01:24
It is important to understand that a hydraulic model is not assumed to be an exact representation of reality.
01:32
Rather, it is a prediction of reality.
01:35
Therefore, a measure of accuracy is known in the data used to build your model,
01:39
and that is correlated to a confidence level in your simulation analysis.
01:44
This graph demonstrates a fundamental truth of hydraulic modeling, in terms of model confidence.
01:51
The bigger the project, or the more complex the problem, the higher the confidence required from the model outputs.
01:58
Therefore, more confidence is required from your model inputs.
02:03
While many hydraulic packages quote values to the nearest millimeter or even smaller,
02:07
model resolution is not the same as model confidence.
02:12
Model confidence is a measure of assumptions.
02:16
For model confidence to be improved, the number of assumptions that are being made must therefore be reduced.
02:23
Back in the 1990s, models were extremely skeletal with lumped hydrology, and contained only the main arterial trunk network.
02:31
As software and hardware improved, it became possible to model more complex systems.
02:37
For example, whole pipe models that include private drainage, like those used in ICM’s predecessor, InfoWorks CS.
02:45
These model types, especially detailed 1D models, are still useful in the decision-making process.
02:52
But today, whole system models are often required to accurately capture the complex interaction of the flooding mechanisms.
03:00
The water industry is now using whole system or integrated modeling to analyze and resolve issues.
03:07
As more resources are placed into a model, the number of assumptions can be reduced, which increases confidence in that model's outputs.
