Major projects
Ongoing
- Hydrometry actions (Flood forecasting Schapi-INRAE annual cooperation, since 2008) on the uncertainty analysis of streamflow measurements and data and the improvement of operational hydrometric practices
- Rhône Sediment Observatory – OSR (Plan Rhône/FEDER, 2009-2020) on the dynamics of sediments and associated contaminants in the Rhône, from Lake Geneva to the Mediterranean Sea. Development of a network of hydro-sedimentary stations and a 1D hydro-sedimentary model of the Rhône from Lake Geneva to the sea.
- ContinuumMES (RMC Water Agency, 2020-2021): evaluation of long-term scenarios by integrated hydro-sedimentary modelling of the Rhone catchment – Rhône River – Gulf of Lion land-sea continuum. Collaboration with Ifremer Brest (Romaric Verney) in particular.
- WMO expert panel (since 2008) on “Evaluation of the performance of flow measurement instruments and techniques”. IAHS representative
- Deposition and Erosion of fine sediment in Alpine Rivers – DEAR (ANR, 2019-2022) on the dynamics of fine sediment and gravel bars in alpine rivers.
Past
- FloodScale / HyMEX (ANR, 2012-2015) on the observation and modelling of flash floods in Mediterranean regions on a series of spatial scales ranging from hillside to regional catchment.
- AWATERE (2015-2016): a one-year scientific stay at NIWA, Christchurch, New Zealand, to work with Graeme Smart, Hilary McMillan and others on alternative river gauging technologies and analysis of uncertainty in flow records in rivers with unstable riverbeds. Related to the PHC Dumont d’Urville project (2015-2016).
- Redynamisation of the Old-Rhine (InterReg FR-DE, 2008-2012): evaluation of the feasibility, risks and effectiveness of artificial sediment input using 1D and 2D modelling (cf. PhD of C. Béraud).
- Bilateral PHC projects: PHC Stefanik (2008-2009, 2012-2013) with VUVH (Bratislava, Slovakia) on morphological changes in large developed rivers, PHC Sakura (2008-2009) with DPRI (Kyoto University, Japan), PHC Dumont d’Urville (2015-2016) with NIWA (Christchurch, NZ).
- Mekong (2012, 2013) and Amazon (2014) field campaigns to estimate total solid transport (graded haulage and suspension), in particular using hydro-acoustic measures. Collaboration on the Mekong with Cerege, MRC and CNR, on the Amazon with IRD, Manaus University and HyBAM Observatory.
- MESURE (ANR ASTRID Maturation, 2017-2020): development of measurement and modelling methods for the hydro-acoustic quantification of suspended solids.
