 The stakeholders and practitioners of simulation


9:00-9:30 : Introduction:

·         What do we model, what results do we get? - Anatomy of modelling systems foundations
Jean A. Cunge , Expert SHF, (France)


9:30-10:45 : Round table 1: New requirements for hydroinformatics: Project owners expressions

Themes for discussion:

This round table will be focused on the role of hydroinformatics technologies in the development and implementation of ambitious projects dealing with infrastructures – coastal & continental infrastructure – and water services – smart metering, environment monitoring, etc.

How hydroinformatics is currently used to provide relevant information to the project developers in order to improve quality of the planned infrastructure, satisfaction of users and public, financial investment? What do the developers expect and require from the hydroinformatics technologies?

The new emerging technical resources, mainly in the ICT domain, offer the possibility to improve strongly the management processes in the water domain (among others, e.g., data acquisition and assimilation for flood forecasting) . How such evolution is integrated into the hydroinformatics environment and how far is it requesting a shift of paradigm in the on-going approaches?

The public awareness is a major challenge for many water related issues such as disaster prevention. The information flow towards the public has to be permanently adapted to an evolving society requesting a more and more accurate and reliable data. How hydroinformatics can integrate such expectation and provide efficient tools to the project developers ensuring both technical and public information?

In this context, how well the modellers understand decision makers’ problems, and vice-versa? How and which new requirements have to be integrated in the new hydroinformatics environments in order to improve efficiency?


10:45-11:15: Coffee break


11:15-12:30 : Round table 2 : From simulation towards decision: Communication of information to stakeholders.

Themes for discussion

Results of the models (of simulations) are most often used for three domains concerning water sector:

- Policy of developments and projects, decisions of investments.

- Crisis management (floods).

- Management of the systems such as urban networks, energy or irrigation systems.

- Flood forecasting
- Etc.

The Round table discussion will focus on the decision taking processes in these domains:

how the decisions taken are stemming from, are being supported by, take into account, simulation results. Simulation models represent only partially and imperfectly the complex reality, this representation being limited by our knowledge of physics and terrain, by available software, by the budgets available for development and applications of the software.

Consequently the results cannot be considered as certain and accurate. Suggested specific subjects for the discussion would be:

- How the decision makers adapt their reasoning to the simulation results. How do they evaluate the validity of the results they are supplied with?

- What is the role of quantification of uncertainty in results? How are the results uncertainties taken into account? How can the uncertainties be reduced (improving models, networks of data collection, data assimilation)?

- How, on one hand, software developers and, on the other hand, software users (e.g. consultants) communicate with decision makers (i.e. their clients)? How do they deal in this communication process with the problems of uncertainties or the degree of approximation of the results supplied to the clients? Are the problems related to engineering ethics considered?

- How the decision makers use the simulation results in their dialogue with citizens and public opinion? Through which means? And how do they deal with uncertainties of the results? Quantification and reduction of uncertainties.

- And media? What is the state of forwarding to the media and then to the public of information stemming from simulations? And how uncertainties of the results are dealt with in this context?
