FIELD

OF

EXPERTISE Rainfall-runoff modelling for flood and low-flow forecasting Hydraulic modelling for flood risk mitigation

Key qualification

Julien Lerat has 10 years of expertise in surface water modelling. His first working experience in India provided him with a broad overview of the water sector and convinced him to start a career in this multi-faceted sector. Back in France, he joined a branch of the Suez-Lyonnaise des eaux group specialised in environmental engineering consulting (Safege). There he managed projects dealing with flood risk mitigation for the benefit of French public authorities. Facing the shortcomings of existing hydrological and hydraulic modelling tools, he decided to join a research institute (Cemagref) to develop new methodologies in this field. His work has materialised with the realisation of a PhD entitled “Which hydrological inputs for hydraulic models? Toward an integrated model for flood modeling”. At the same time, he has participated in international projects dealing with rainfall-runoff modelling.
