Support to project (ex. Douro river inlet breakwaters)

Project an impact assessment of new inlet protection

breakwaters. This included quite innovative solutions

which were awarded with Secil Prize 2009 (the most

relevant engineering prize in Portugal)

Support to project (ex. new Lisbon port containers terminal)

Goal: Receive ship containers with a capacity of 8,000 TEU reaching about 352

meters long, 43 meters mouth and 14.5 meters draft

HIDROMOD is responsible for all the modelling studies necessary to support both the engineering and the

environmental impact assessment studies. This includes all the aspects associated with the wave climate,

hydrodynamics and transport processes, including the assessment of the channel maintenance conditions,

potential impacts associated with the dredging works and the suitability of the places selected to dispose the

dredged material.

Basically it means to take the most advantage of the available technology (modelling and data

management) to improve the knowledge about the systems and, by this way, take more

informed actions, adopt more safe and efficient procedures and contribute to improve

environment while saving money.

Optimizing the Operation and Management Trough Modelling,

Data Mining and Machine Learning

What does this mean?

What is the challenge

With the growing investments in telemetry and monitoring it is being generated huge amounts of

data that requires innovative approaches to be properly used in benefit of the organizations.

Data and information are two quite different things and having data does not mean having

information…

Adopt a preventive attitude

Making a wider use of these advanced modelling and data management tools helps to move

the focus to prevention and knowledge instead of the traditional reactive approaches

The improvement in the systems intelligence enables to automatically detect anomalies,

establish cause-effect relations and support to early warning

If the causes are not properly assessed the answers may not be the most

proper and/or the most efficient…

AQUASAFE an easy to use tool to accomplish these goals

The AQUASAFE server stores and indexes internally generated

system data (models), or through external links (Scada systems,

FTP, Open DAP, etc.). Apart from this distributor role, it also

schedules tasks, such as running models, creating reports, etc.

AQUASAFE was distinguished by IWA which attributed it the Honour Award for

the Operations & Management Category of the 2012 IWA Project Innovation Awards.

Benefits

AQUASAFE may help to:

Improve and optimize monitoring programs (water sources, water discharges, urban networks…),

Properly assess the effectiveness (or need) of additional water treatments,

Reduce water losses,

Optimize energy,

Keep running warning/alert systems (beach water quality, leakages, anomalous parameters, …),

Derive Key Performance Indicators,

…

Taking the example of the Lisbon Metropolitan Area

Discharges in the sea benefits of advection/diffusion and of low residence time

Two quite different areas: • the estuary (with water residence

times from days to weeks) • The coast

Is there a need for secondary treatment

in the coastal area or removing nutrients

in the estuary?

Solution designed in the early eighties, entered into function in the nineties. It was based on a long trunk sewer (25 km) a preliminary treatment plant and a 2.9km submarine outfall with 2*400m diffusers.

However the publication of the UWWT Directive came to impose secondary treatment unless it may be demonstrated that there was no benefit.

A derogation of the secondary treatment was accorded in

2000 based on intensive monitoring and modelling studies.

Inside the estuary

Secondary treatment is mandatory by law!!

To answer this question a monitoring program supported by data and a

biogeochemical model was implemented considering all the loads.

Is there a need to remove nutrients?

After all…

More than 100 million euros of initial investment were saved,

More than 20 million/year of exploitation costs were saved,

None of that money would be used to protect the environment. Most would be used

just to produce CO2 …

16:31 25

Nutrients removal would have no benefit!!!

Secondary treatment has been adopted

Keep properly informed. Use data to check status and produce KPIs

Note

The success of all these tools and procedures depends on its capability to answer to

the real problems of operation and management

In this perspective it is of prime importance to gather as much of experiences as

possible in the requirements definitions

Your experience it is important to us!
