L'exploitation d'un système moderne d'alimentation en eau potable nécessite une surveillance permanente de la qualité de l'eau au sein des usines de production et sur le réseau de distribution, face à des risques de contamination accidentelle ou terroriste. Cette surveillance s'appuie usuellement sur un ensemble de capteurs déployés en des points s...
The world is witnessing major environmental changes, which are a consequence of increasing impacts and pressure on the natural system. Hydrological processes at the catchment scale are sensitive to these changes, and the resulting effect is an increase in the frequency of extreme events such as flooding and droughts, which cause serious damages to ...

Floods represent one of the major natural disasters that are often responsible for fatalities and economic losses. Flood warning systems are needed to anticipate the arrival of severe events and mitigate their impacts. Flood alerts are particularly important for risk management and response in the nowcasting of flash floods. In this case, precipita...
Precipitation fields are crucial for hydrological forecasting. A forecasting system comprising a rainfall-runoff model uses observed and forecast precipitation to forecast discharges several hours to days ahead, which will be used for flood alert and risk management. Many sources of uncertainty play a role in a hydrological forecasting system, incl...
Forward Collision Warning Systems (FCWS) are expected to assist drivers; however, it is not completely clear whether these systems are of benefit to distracted drivers as much as they are to undistracted drivers. This study aims at investigating further the analysis of the effectiveness of a surrogate FCWS according to the attentional state of part...
The impact forces are the vertical component of the road/tyre interface. These forces are important to calculate road and bridge damage or to assess the Load Transfer Ratio (LTR) used to prevent rollover situation of heavy vehicles. A good evaluation of these forces requires an accurate description of the road profile, which is an input to the heav...
Actuellement, de nouveaux schémas directeurs de prévision de crues sont en cours d'élaboration en France. Dans ce domaine, il y a toujours d'un côté, les cours d'eau pour lesquels on dispose en temps réel d'une information sur les pluies au sol et sur les débits, et d'un autre côté, les cours d'eau où aucune information en temps réel sur les débits...
