The specific orography of the Countries bordering the Mediterranean makes flash floods the most frequent risk. While their prediction require the joint use of meteorological and hydrological models, a number of issues remain still not fully resolved at the scale at which meteorological and hydrological processes interact. A better understanding of these interactions will lead to the identification of the most appropriate scale of representation of the physical phenomena, resulting in more reliable predictions.
In this framework, observations play a fundamental role: the integrated use of multi-scale multi-source observations - through the application of blending techniques, data fusion and data assimilation - is essential for the understanding of the physics of the phenomena and their relevant scales of interaction.
Contributions assessing aspects relevant to the observation of rainfall, soil moisture and discharge at proper scales for flash flood prediction, both with traditional and remote sensors; analysis of large databases for the understanding of the physics and dynamics of involved hydro-meteorological processes at different scales and improvement of models derived from the analysis and comparison between observations and model outputs, are strongly encouraged to submit to this session.
