Climate is changing…
There are many factors leading to
changes in the rate of climate change
Whatever the main reason is, the climate variations prompt for
developing the water management strategies
that take climate uncertainties into account
the need for
More observation systems
Better predictive modelling tools
Analytical methods to handle uncertainty
Changes in design and adaptive management practices
Changes in educational programmes at all levels
These issues are the current focus of Hydroinformatics 6

4. Encapsulation of knowledge
related to water
Tacit (implicit) knowledge embedded within a person
Words, texts, images
printed
stored in electronic media
Mathematical models
formulas, algorithms
algorithms encapsulated in computer programs
(software)
Integrated systems encapsulating all of above -
Hydroinformatics systems

Modelling
is the heart of Hydroinformatics
11
D.P. Solomatine. Hydroinformatics.
Modelling
Model is …
a simplified description of reality
an encapsulation of knowledge about a particular physical or
social process in electronic form
Goals of modelling are:
understand the studied system or domain (the past)
predict the future
use the results of modelling for making decisions (change
the future)
12
D.P. Solomatine. Hydroinformatics.
7. Modelling is at heart of Hydroinformatics
Hydroinformatics deals with the technologies ensuring the
whole information cycle, and integrates
data,
models,
people
13
D.P. Solomatine. Hydroinformatics.
Main modelling paradigms
Physically-based model (process, simulation, numerical) is
based on the understanding of the underlying processes
Data-driven model is based on the recorded values of
variables characterising the system. They need less
knowledge about the physical behaviour
Agent-based model consists of dynamically interacting
relatively simple rule-based computational codes (agents)
14
D.P. Solomatine. Hydroinformatics.
8. Applications of models
River/urban flood forecasting and management
Reservoir operations
Sediment transport and morphology
Ecology and water quality
Storm surges and coastal flooding
Dredging and reclamation
Urban sewers and drainage
Water distribution networks
etc.

Example: a physically-based model of open
channel flow: Saint Venant equations
The 1D continuity and momentum equations for open
channel flow are also referred as Saint Venant equation
Form a pair of non-linear hyperbolic partial differential equations

Analytically can not be solved

9. Why 2D/3D modelling?
Often 1D model is not enough
Horizontal velocity fields Vertical velocity fields

Some examples of using modelling
in water-related issues
18
D.P. Solomatine. Hydroinformatics.
10. Warragamba Dam, Australia
Warragamba Dam - 65 km west of
Sydney in the Burragorang Valley
provides the major water supply for
Sydney
Warragamba River flows through a
300-600 m wide gorge, about 100 m
deep before opening out into a large
valley. This allows a relatively short
and high dam to impound a vast
quantity of water.
A dam break of the Warragamba
Dam would be a major disaster.
SOBEK (Delft Hydraulics) software
was used for simulation 19

Data-Driven Modelling

Also useful as emulators of complex physically-based
models (surrogate models)

19. MULTI-OBJECTIVE OPTIMIZATION
Finding variables’ values that bring the value of the
“objective function” to a minimum
In water resources many problems require solving an
optimization problem
37
D.P. Solomatine. Hydroinformatics.
Many optimization problems in water
resources are multi-objective
there are several objectives that are to be optimized
often they are in conflict, i.e. minimizing one does not
mean minimizing another one
a solution (the set of decision variables) is always a
compromise
Examples:
multi-purpose reservoir operation
electricity generation vs. irrigation vs. navigability
models calibration (error minimization)
models good "on average" vs. good for particular hydrologic
conditions (floods)
pipe networks optimization (design and rehabilitation)
costs vs. reduction of flood damage

21. INFORMATION THEORY
Shannon entropy provides a mathematical framework to evaluate
the amount of information contained in a data series
H = −∑ p log2 p
Average mutual information (AMI) is measure of information
available from one set of data having knowledge of another set
of data
AMI can be used to investigate dependencies and lag effects in
time series data
⎡ PXY ( xi , y j ) ⎤
AMI= ∑ PXY ( xi , y j ) log 2 ⎢ ⎥
i, j ⎢ PX ( xi ) P ( y j ) ⎥
⎣ Y ⎦

23. UNCERTAINTY
Uncertainties associated with climate change are very high
Different IPCC scenarios lead to very different results of
water models
Any study exploring the impacts of CC needs powerful
tools for analysing and predicting uncertainty

Most methods are aimed at analysing average model uncertainty, but
not predicting it for the new inputs
Most uncertainty analysis studies focus on the parametric uncertainty
only. More has to be done to analyse and predict:
Input data uncertainty
Residual uncertainty (uncertainty associated with the deficiencies
of the “optimal” model)
Model uncertainty is estimated. What next?:
Should we combine in an ensemble several “good” models,
instead of using one calibrated model?
How can we predict model uncertainty for the future situations?
How to communicate uncertainty to decision makers?

D.P. Solomatine, D.L. Shrestha. A novel method to estimate model uncertainty using machine
learning techniques. Water Resources Res., 45, W00B11, doi:10.1029/ 2008WR006839, 2009.
A calibrated model M of a water system is considered
M is run for the past hydrometeorological events
It is assumed that the errors of model M characterize the
“residual” uncertainty in different situations (events)
This data is used to train the machine learning model U
that predicts the error (uncertainty) of model M, which is
specific for a particular hydrometeorological event
UNEEC-M: parametric and input uncertainty is added as
well

34. Conclusion
Hydroinformatics is a unifying approach to water
modelling and management
Specialists in hydroinformatics play an integrating role
linking various specialists and decision makers
Access to information by widening groups of stakeholders
leads to democratisation of water services
One of the roles of Hydroinformatics is developing
analytical methods to deal with climatic variability in
modelling and management practice
Focus should be on education and training
