National Initiatives
ANR SEDIFLO (2015-2019)
Participants : Emmanuel Audusse, Martin Parisot.
-
Program: ANR Défi 1 “Gestion sobre des ressources et adaptation au changement climatique” (JCJC)
-
Project title: Modelling and simulation of solid transport in rivers
Based on recent theoretical and experimental results, this project is aimed at modelling transport of sediments within rivers. It will rely on innovations from the point of view of rheology as well as advanced mathematical tools (asymptotic model reduction, PDE discretisation).
ANR Hyflo-Eflu (2016-2020)
Participants : Jérémy Ledoux, Martin Parisot, Jacques Sainte-Marie, Julien Salomon.
The project is a collaboration between the Inria-team ANGE, specialist of free surface flow and optimisation, and the industrial developers of the turbine, HYDROTUBE ENERGIE. The objective of the project HyFlo-EFlu is to deliver a numerical software able to simulate the dynamic of a floating water turbine in real context. For the academic partner, the main challenge is in the simulation of the floating structure at the scale of the river, and the modelling of the vertical and horisontal axis turbine. For the industrial partner, the objective is the validation of the stability of the structure and the performance in term of energy production.
ANR MIMOSA (2014–2017)
Participants : Marie-Odile Bristeau, Anne Mangeney, Bernard Di Martino, Jacques Sainte-Marie.

Project title: MIcroseism modelling and Seismic Applications
Seismic noise is recorded by broadband seismometers in the absence of earthquakes. It is generated by the atmosphere-ocean system with different mechanisms in the different frequency bands. Even though some mechanisms have been known for decades, an integrated understanding of the noise in the broadband period band 1-300sec is still missing. Using novel theoretical, numerical and signal processing methods, this project will provide a unified understanding of the noise sources and quantitative models for broadband noise. Conversely, we will be able to interpret seismic noise in terms of ocean wave properties. This first analysis step will lead to the identification and characterisation of source events, which we will use to improve noise tomography, and seismic monitoring.
ANR CHARMS (2016-2020)
Participant : Cindy Guichard.
-
ANR project call: Transformations et inter-conversions énergétiques
-
Project title: Modèles de réservoirs quantitatifs pour les systèmes hydrothermaux complexes
-
Funding: 73k euros for LJLL (in 767k euros for the whole project)
CHARMS ANR project is focused on the mathematical methods and software tools dedicated to the simulation of the physical models issued from geothermal engineering. The final objective is the achievement of a highly parallel code, validated on realistic cases.
CNRS Moset (2016-2017)
Participants : Emmanuel Audusse, Martin Parisot.
In collaboration with G. Antoine (EDF), S. Boyaval (LHSV), C. Le Bouteiller (Irstea), M. Jodeau (EDF).
Gathering mathematicians (numerical analysis) and geophysicists, this project focuses on the quantitative prediction of solid transport. This issue raises several questions about rheology when the sediment concentration is high enough. It is crucial for modelling the dynamics of suspension. The collaboration aims at assessing models by means of experimental data and at providing preliminary numerical results to evaluate the order of magnitude of constraints.
CNRS Simulations of free-surface flows (2017)
Participants : Cindy Guichard, Martin Parisot, Yohan Penel, Jacques Sainte-Marie.
In collaboration with E. Fernaández-Nieto.
Free-surface flows are extensively studied in the literature by means of simplified models (like the Shallow Water equations) due to the theoretical and numerical issues related to the Euler system. Intermediate models have then been derived to improve the accuracy and the physical relevance (e.g. taking into account hydrodynamic pressure or multilayer approaches). This collaboration aims at designing a hierarchy of multilayer models with a non-hydrostatic pressure as a discretisation along the vertical axis of the Euler equations. The hierarchy relies on the degree of approximation of the variables discretised with a Discontinuous Galerkin method for the vertical direction. These innovative models will imply a theoretical study and the development of numerical tools in dimensions 1 and 2 before the modelling of other physical phenomena (viscosity effects, ...).
CNRS Mocha (2017-2018)
Participant : Martin Parisot.
In collaboration with S. Barthélémy, N. Goutal, S. Ricci, M. Hoang Le.
Multi-dimensionnal coupling in river hydrodynamics offers a conveninent solution to properly model complex flow while limiting the computational cost and making the most of pre-exsiting models. The project aims to adapt the lateral interface coupling proposed in [39] to the implicit version and test it on real data for the Garonne River.
Inria Project Lab “Algae in Silico” (2015-2018)
Participants : Marie-Odile Bristeau, Yohan Penel, Jacques Sainte-Marie, Fabien Souillé.
In the aftermath of the ADT In@lgae (2013–2015), we developed a simulation tool for microalgae culture. An Inria Project Lab “Algae in Silico” has started in collaboration with Inria teams BIOCORE and DYLISS. It concerns microalgae culture for biofuel production and the aim is to provide an integrated platform for numerical simulation “from genes to industrial processes”.
Inria Project Lab “CityLab” (2015-2018)
Participants : Vivien Mallet, Raphaël Ventura.
CityLab@Inria studies ICT solutions toward smart cities that promote both social and environmental sustainability.
GdR EGRIN (2013–2017)
Participants : Emmanuel Audusse, Bernard Di Martino, Nicole Goutal, Cindy Guichard, Anne Mangeney, Martin Parisot, Jacques Sainte-Marie.
EGRIN stands for Gravity-driven flows and natural hazards. J. Sainte-Marie is the head of the scientific committee of this CNRS research group and A. Mangeney is a member of the committee. Other members of the team involved in the project are local correspondents. The scientific goals of this project are the modelling, analysis and simulation of complex fluids by means of reduced-complexity models in the framework of geophysical flows.
ANR ESTIMAIR (2013-2017)

The project aims to propagate uncertainties in a complete air quality modelling chain at urban scale, from road traffic assignment to air pollutant dispersion.
ANR FireCaster (2017-2020)
Participants : Frédéric Allaire, Vivien Mallet.
The goal of the FireCaster project is to prototype a fire decision support system at the national scale to estimate upcoming fire risk (H+24 to H+48) and in case of crisis, to predict fire front position and local pollution (H+1 to H+12).
ANR CENSE (2017-2020)

Project title: Caractérisation des environnements sonores urbains : vers une approche globale associant données libres, mesures et modélisations
