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 acronym: SEDIFLO

• Project title: Modelling and simulation of solid transport in rivers

• Coordinator: Sébastien Boyaval (LHSV/ENPC)

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 : Martin Parisot, Jacques Sainte-Marie, Julien Salomon.

• Appel à projets ANR : Energies marines renouvelables

• Project acronym: Hyflo-Eflu

• Project title: Hydroliennes flottantes et énergie fluviale

• Coordinator: Julien Salomon

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. Thanks to the collaboration between a team of mathematician specialist of free surface flow and optimization and the industrial developers of the turbine. 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 horizontal 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 : Nora Aïssiouene, Marie-Odile Bristeau, Anne Mangeney, Bernard Di Martino, Jacques Sainte-Marie.

• Program: ANR Défi 1 “Gestion sobre des ressources et adaptation au changement climatique”

• Project acronym: MIMOSA

• Project title: MIcroseism MOdeling and Seismic Applications

• Coordinator: Eleonore Stutzmann (IPGP)

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 characterization of source events, which we will use to improve noise tomography, and seismic monitoring.

ANR LANDQUAKES (2012–2016)

• Program: ANR Blanc “Mathématiques et interactions”

• Project acronym: LANDQUAKES

• Project title: Modélisation des glissements de terrain et des ondes sismiques générées pour détecter et comprendre les instabilités gravitaires

• Coordinator: Anne Mangeney

Within the ANR domain “Mathematics and Interfaces”, this ANR project (between Univ. Paris-Est – LAMA, Univ. Denis Diderot Paris 7 – IPGP, Univ. Nantes – LPGN, Univ. Strasbourg EOST, $180.000$ euros) deals with the mathematical and numerical modelling of landslides and generated seismic waves.

A. Mangeney is also involved in the CARIB ANR program (2014–2017) entitled “Comprendre les processus de construction et de destruction des volcans de l'Arc des Petites Antilles”.

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.

Inria Project Lab “Algae in Silico” (2015-2018)

Participants : Nora Aïssiouene, Marie-Odile Bristeau, David Froger, Raouf Hamouda, Jacques Sainte-Marie.

In the framework of the ADT Inlgae (2013–2015), we developed in collaboration with the BIOCORE Inria project-team a simulation tool for microalgae culture. An Inria Project Lab “Algae in Silico” has started in collaboration with several Inria teams, many 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”.

ANR project HJnet (2013–2015)

Participant : Edwige Godlewski.

This research project consists in studying Hamilton-Jacobi equations on networks, and more generally on heterogeneous structures. This theoretical problem has several potential applications, in particular to traffic flow theory.

Hydraulics for environment and sustainable development (HED${}^2$)

The scienfitic group (GIS in French), which includes Inria and the ANGE team, brings together scientists and engineers involved in hydraulics, risk management and sustainable development. It results in a continuum between fundamental research, applied research and engineering. On the one hand, the ANGE team can be provided with experimental measurements (erosion, long waves, fluid structure interactions,...) thanks to this collaboration; on the other hand, the GIS can favor the transfer of numerical tools and scientific results.
