Seine River Basin

Nicolas Flipo’s research is dedicated to the sustainable management of water resources. He therefore develops modeling approaches to simulate the qualitative and quantitative fates of water bodies including surface water, especially rivers, and groundwater. For his PhD and habilitation thesis he developed a systemic view of hydrosystems integrated at the basin or catchment scale. He entered the PIREN Seine research program in 2000 focusing on the simulation of nitrate fluxes related to agricultural practices at the basin scale over several decades. Since then he reinforced within the program an interdisciplinary approach for water management, as illustrated by more than forty scientific papers and eighty participations to international conferences. He is the head of the research programme since 2015 and a research director at MINES ParisTech, Paris Sciences and Lettres University, where he leads the coupled hydrology-hydrogeology research group.Pierre Labadie is an analytical and environmental chemist at the CNRS, currently based at the University of Bordeaux. His research activities focus on the study of the occurrence, fate (including bioaccumulation and trophic transfer) and impact of organic pollutants of emerging concern in aquatic ecosystems, for instance in river-estuarine-coastal zone systems. Special emphasis is put on organohalogens such as poly- and per-fluoroalkyl substances (PFASs), flame retardants or chlorinated paraffins. He joined the PIREN-Seine programme in 2006 and, since then, his work has often been performed in an interdisciplinary framework, at the interface with ecotoxicology and trophic ecology.Laurence Lestel is an environmental historian, looking for the environmental impact of increasing industrialization and urbanization in France, 19th and 20th century. She entered the PIREN Seine research program in 2000, to understand the link between the uses of metals in society and river contamination. Since then, she has been coordinating interdisciplinary research programs on river systems. The aim of her work is to analyse how environmental issues were detected and managed by several types of actors: State, experts, public opinion, and the effect of their action on river quality. She is a research director at the CNRS in an interdisciplinary section on “Social environments: from fundamentals to operations”.
