SimHydro 2014

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 modeling and request
innovation in methodology and concepts for a real integration into
the decision-makings processes.
With respect to these issues, a number of questions remain open:
coupling of models, data acquisition & management, uncertainties,
use of 3D CFD, models for complex phenomena and for large scale
problems, modeling of multiphase flows as well as 3D modeling of
Free Surface Flows and difficult challenges of modeling in
Multiphase Flows ... All those points will be addressed and discussed
during SimHydro 2014 with a special emphasis on fast hydraulic
Following the two SimHydro conferences, which were focused upon
uncertainties and coupling in hydroinformatics and fluid modeling in
2010 and on the new frontiers of simulation in 2012, the purpose of
SimHydro 2014 is to focus the debate on the modeling and
simulation of fast hydraulic transients, on 3D modeling, on
uncertainties and multiphase flows. The conference will allow to
explore both limits and performances of actual models and also to
present the most recent developments based on new numerical
schemes, high performance computing, multiphysics and multiscale,
methods, and better interaction with field or scale models data.
Practitioners, stakeholders, researchers and engineers are welcome
to participate. Presentations of practical studies are encouraged.

New frontiers in simulation, Uncertainties &
Fast hydraulic transients modeling
The challenge of rapid transient flows:
expectations and experience feedback from
stakeholders and practitioners
3D CFD and applications to near field phenomena
in free surface flows & Multiphase flows
Fast transient flows like dam breaking waves, flash floods and
tsunamis represents extreme phenomena which are affecting
deeply human activities and societies. Various mechanisms have
been developed and implemented in order to mitigate effects and
reduce vulnerability. In such procedure, models and forecasting
tools – including communication issues – appear now as a central
component for the engineers and utilities managers. At the same
time, these models become the interface with a second group of
stakeholders and decision makers such as elected representatives,
NGOs, investors, governments, local and central, and in general,
Do the developers and researchers on the one hand, and the
stakeholders on the other, know each other well enough to
exchange information and clearly express concerns about the
limits and the potential of the models? What are the expectations
of the professionals and decision makers in charge of emergency
responses? What are the lessons learned about models and
simulations from previously recorded events?
What is the state-of-the-art in research and development in the
domain of numerical fluid mechanics? What numerical problems
are only poorly solved or unsolved for more and more complex
approaches such as 2D, 3D: the links between hydrodynamics,
turbulent diffusion, transport phenomena? What is the state-ofthe-art in multi-scale modeling and multi-physics modeling?
What are the new trends in modeling today? What are the main
questions about uncertainties? What are the main challenges for
fast transient flows? Coupled models and their interaction with
