Olivier Cerdan
Researcher in BRGM’s Risks and Prevention Department. After completing his PhD on soil modeling at INRA’s Soil Science Laboratory in Orléans, he went on to complete a European MARIE CURIE post-doctoral fellowship at the Laboratory of Experimental Geomorphology at the University of LEUVEN, where he worked on setting up and validating a European soil erosion map. His main interests include land degradation processes, soil mapping and modeling at different spatial and temporal scales. Designer of the STREAM model, he also coordinates projects aimed at linking slope transfers and sediment exports in rivers. In addition to his scientific research activities, these include participation in national and European assessment committees, teaching in various institutions and supervising doctoral and post-doctoral students.
Thomas Grangeon
PhD working in BRGM’s Risks and Prevention Department. His work aims to improve understanding of soil erosion and sediment transfer at catchment scale, by combining experimental approaches, including process studies and field monitoring, with numerical approaches. His recent work has focused on parameterizing the genesis of runoff and erosion within numerical models, and proposing a new method for modeling sediment deposition over the entire hydrographic network of different watersheds.
Valentin Landemaine
Doctorate in geomorphology from BRGM’s Risks and Prevention Department. Her PhD focused on understanding soil erosion and hydrosedimentary transfers from the agricultural plot to the watershed scale in the Seine-Maritime region. Initially trained in the geosciences, covering a broad spectrum of disciplines required to understand the global functioning of a watershed, he has specialized in the development of methods for quantifying sediment transfers and in modeling runoff and soil erosion. He is responsible for the development of the WaterSed model. He carries out expert missions for public policies and pursues his research and development activities through national and international projects.
Rosalie Vandromme
Geotechnical engineer with a doctorate in sedimentology from BRGM’s Risks and Prevention department, Rosalie Vandromme has acquired solid experience during her seven years with BRGM as a research engineer. She monitored and managed a number of expert assessment and research projects, mainly focusing on hazards associated with ground movements (landslides and clay shrink-swell). She took part in the development of an earth movement susceptibility modeling tool (ALICE) applicable from local to regional scales. She also took part in the assessment of ground movement hazards in the post-mining sector in France.
