Research

Research interests :

•   Extreme hydrological events (floods, droughts, heavy rainfall, sediment)

•   Statistical hydrology (frequency analysis, regionalization methods, geostatistics)

•   Rainfall-runoff modeling (flood processes, water resources)

•   Climate change impacts on hydrology (non-stationary models, downscaling)

My research activities are focused on the Hydrological hazards in the Mediterranean region

The area of ​​Mediterranean climate is very sensitive to extreme hydro-climatic events, in particular floods, the main hazard causing human and economic damage in countries bordering the Mediterranean Sea, but also droughts, that may impact large areas. Modeling these extreme events is a major scientific challenge to improve the forecasting and warning systems. The development of regional approaches can overcome the lack of measurements and allows generalizing the information available from the existing monitoring networks. The main scientific objective is to improve the modeling of extreme hydrological events in the Mediterranean region. The two main topics are:

Improve the knowledge on the hazards, using frequency analysis techniques or hydrological models to estimate the return periods of extreme hydro-meteorological events. With regionalization methods, the data available from the monitoring networks can be extended to the ungauged sites. This topic is associated with the study of climate change impacts on extreme events in the Mediterranean region, using climate model outputs downscaled to the area of interest.

Reduction of the vulnerability, using flood modelling and forecasting methods. This topic is based on rainfall-runoff modeling and model calibration in a regional context, using operational models. This theme is also connected to the development of  warning systems for the populations (through the assimilation of weather forecasts and real-time data into hydrological models).
