摘要

The hydrological analysis of the floods of the 12, 13 and 14 novembre 1999 which affected the Agly, Aude, Orbieu and Tarn river basins shows the importance of the specific flow rates when the flood is at its heights (from 0,5 to 3,6m3/s/km2 and maximum flows of 1100 m3/s on the Agly and 2000 m3/s on the Aude). Such flow rates are not exceptional on the coastal rivers of the Mediterranean. Acceptance of their importance means reassessing protective measures which until now had been judged adequate.
