Mobility project

Continuous measurement of sediment nutrient release for the improved prediction of harmful algal blooms in shallow lakes

Harmful algal blooms threaten lake and reservoir ecosystems and ecosystem services worldwide. Until lake water quality is improved, early warning systems are needed to protect populations.

In shallow lakes, wind mixing enhances nutrient diffusion and particle resuspension from the sediment. This internal nutrient load is often larger than the external load from inflows, and is a key for good predictions of harmful algal blooms. Its intermittency makes continuous measurements necessary, but current measurements are either discrete or indirect. During this project, we will set up a direct continuous measuring system for the nutrient release from the sediment of shallow lakes.

Biography & research interests

I studied physics at Ecole normale supérieure in Paris. During my PhD at Paris-Sud University, I investigated the physical properties of suspensions of goethite nanorods in water, a mineral liquid crystal, focusing on their orientation and crystallization in magnetic and electric fields. This work combined experimental work at lab and at synchrotrons with modelling.

After I joined the French corps of civil and environmental engineers, I prepared a master degree in civil and environmental engineering at Ecole des Ponts ParisTech. I managed for four years a technical team specialized in port and waterways planning at the ministry for transport (now CEREMA). I contributed to promoting European research to the port industry and to transnational calls for proposals.

Since 2008, I have been associate professor at AgroParisTech in Paris. I teach hydrology and urban hydrology in master and advanced master courses in environmental engineering and water management. My research at the Laboratory for Water, Environment and Urban Systems (LEESU), a joint laboratory of University Paris-Est Créteil, Ecole des Ponts ParisTech and AgroParisTech, deals with the monitoring and the hydrodynamic-biogeochemical modelling of ponds, lakes and reservoirs under different climates, in France, Brazil, Canada and Lebanon. I have a strong interest for early warning systems of phytoplankton blooms: this project at Coblence-Landau University focuses on one of their drivers in shallow ponds and lakes, the nutrient release from the sediment.
