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 : Jérérmy Ledoux, Martin Parisot, Jacques Sainte-Marie, Julien Salomon.
The project is a collaboration between the Inria-team ANGE, specialist of free surface flow and optimization, 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 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.
CNRS CORSURF (2016)
Participants : Bernard Di Martino, Cindy Guichard, Anne Mangeney, Jacques Sainte-Marie.
In collaboration with E. Fernández-Nieto (Sevilla, Spain).
Geophysical flows like avalanches (mud, snow) or landslides involve surface flows with non-Newtonian fluids. The goal is to develop numerical models, both accurate with respect to the material behavior and industrially efficient.
CNRS MOCHA (2016)
Participant : Martin Parisot.
Multi-dimensionnal coupling in river hydrodynamics offers a convenient solution to properly model complex flow while limiting the computational cost and making the most of pre-existing models. The project aims to adapt the lateral interface coupling proposed in [37] to the implicit version and test it on real data for the Garonne River.
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.
Inria Project Lab “Algae in Silico” (2015-2018)
Participants : Nora Aïssiouene, Marie-Odile Bristeau, David Froger, Yohan Penel, Jacques Sainte-Marie, Fabien Souille.
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”.
ANR MIMOSA (2014–2017)
Participants : Nora Aïssiouene, Marie-Odile Bristeau, Anne Mangeney, Bernard Di Martino, Jacques Sainte-Marie.
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)
Participant : Anne Mangeney.

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