Increasing the forecasting lead-time of weather driven flash-floods

Rapport H01/812/02/D9056/AG/ct de 47 p. [Annexe : p. 32 à 47]This document is organized in two main sections.<br />In the first section we define the problem of flash-flood forecasting and we list the main scientific issues<br />that need to be addressed. In the second section we briefly describe the previous European programmes devoted to flash flood. The dispersion of the efforts within programmes that were not only concerned by flash flood lead to the difficulty to highlight major results. Suggestions for future improvements in flash flood risk reduction are then proposed through research proposals and possible actions at European level. Figures and tables are put together in the ANNEX Section at the end of the document.<br />This report constitutes a first step of the writing of a blueprint dedicated to the storm driven floods in the<br />Mediterranean. This blueprint will be used at national and European level in support to hydrometeorological laboratories and associated research projects
