About SimHydro 2017

Modeling in fluid mechanics, hydraulics, and hydrology, whether using digital tools or using scale models, has reached sufficient maturity to be in daily use by engineers for analysis and for communication. Increasingly complex cases can be handled thanks to ever more sophisticated tools and increasingly abundant computing power. The emerging environment populated with new generation of sensors, using cloud computing resources, is challenging the current practices of modelling and request innovation in methodology and concepts for a real integration into the decision-makings processes. SimHydro conferences, since 2010, have created a regular forum where major actors of the hydroinformatic domain and stackeholders meet, share and debate about needs, innovations and implementations of models and their inputs for decision making.

Following the 3 past successful events in 2010, 2012 and 2014, the next SimHydro Conference will be held from 14th to 16th of June 2017 at Polytech Nice Sophia (School of Engineering) in Sophia Antipolis technopark, near Nice and Cannes - France (French Riviera).

For this new edition, the general theme of the conference will be focused on "Choosing the right model in applied hydraulics".
In performing a simulation study the modeler needs to make decisions about what to include in the simulation model and what to exclude. The modeler is faced with the very difficult choice of determining what is the best model to develop. Make it too complex and it may not be possible to complete the model with the time and knowledge available. Make it too simple and the results may not be sufficiently accurate. In hydraulics and related issues, the choice of the right model is a crucial step that partly determines the decision making process. The increasing availability of models allows today to the modeler to explore various approaches. In such new context, methodologies, guidelines and standards are more and more requested in order to ensure higher efficiency. These major aspects have to be discussed before to be formulated as references. The various sessions of SimHydro 2017 will cover these dimension and will offer to the participants the possibility to share and exchange with scientists, practitioners and decision makers.

The conference is mainly targetting the European audience and endeavor to collect high value papers that will be published in scientific journals and a specific book (Advances in Hydroinformatics) with Springer.

The SimHydro 2017 conference is jointly organized by the Société Hydrotechnique de France (SHF), the University of Nice-Sophia Antipolis (UNSa), the Association Française de Mécannique (AFM), Environmental & Water Resources Institute (EWRI) and the International Association for Hydro-Environment Engineering and Research (IAHR).  

4th International Conference

Choosing the right model in applied hydraulics

Polytech Nice Sophia, 14-16 June 2017

  • Decision-making processes and uncertainies handling
  • Purposes for modelling: how to choose the right model for coupled problems?
  • Which are the industrial and societal issues associated to hydraulic modelling? Which uncertainties and how to deal with?
Main themes
  1. Hydro-environmental issues. Modelling in eco-hydraulics
  2. Uncertainties and data assimilation
  3. Scale models in hydraulics and their place and complementarity in simulation concepts
  4. Flow instabilities in hydraulics: how to deal with?
  5. Real time modelling of Hydraulic structures and networks and events
  6. Lessons learned from 2015 flash floods in the French Riviera (Côte d'Azur) area and other similar areas
  7. Modelling tools for urban floods (pluvial, fluvial, and marine submersions)
  8. 3D two-phase flows (experiments and modelling)
  9. Hydraulic machineries
Special session: Return of Experience - 2015 French Riviera floods

On the 3rd October 2015, the French Riviera has been affected by extreme precipitations that have generated flash floods and inundations in many coastal cities. The recorded event has affected several thousands of inhabitants and killed 19 persons in tragic circumstances. The estimation of the direct damages has reached about € 850 millions. The special session during SimHydro 2017 will allow to come back on the event and to analyse origins, processes and management strategies. The exposed population that doesn’t have a culture of risk, does not always properly understand extreme events combining heavy runoff processes and urban inundations. The session will gathers feedback for local population, victims, first responders and decision makers. The session will be organized in order to maximize the return of experience for the modeller’s community.

Preliminary schedule
  • Day 1 / 14th of June: Free surface flows, coupled problems and hydro-environmental issues.
  • Day 2 / 15th of June: Real-time modelling of hydraulic networks and structures urban flood modelling.
                                      Special session on 2015 French Riviera floods
  • Day 3 / 16th of June: 3D flows modelling and two phase flows in hydraulic machines and industrial hydraulics, Urban flood modelling.
  • October 15th, 2016: November 15th, 2016: Abstract submission

  • December 5th, 2016: Notifications to abstract authors

  • February 27th, 2017: Full paper submission



As for the last two editions, a book gathering a collection of extended papers which will be selected for presentation during the SimHydro 2017 will be published in partmership with Springer. The authors will be invited by the editorial board to submit an extented version of their contributions. The papers will present the state of the art numerical simulation in domains such as (1) New trends in modelling for marine, river & urban hydraulics; (2) Stakeholders & practitioners of simulation; (3) 3D CFD & applications.

All papers will go through a peer review process from the scientific committee members in order to ensure quality, content and originality.

The 2 published books - Advances in Hydroinformatics - are available in hard copy format and as ebook on Spinger website:
