Abstract

The three greatest floods in the Loire River (1846, 1856, and 1866) have been recorded during the period 1840-1870. This period has been also extraordinary by the flood increase in Catalonia and other European regions. The associated meteorological situations have been analyzed by using daily pressure data obtained from some European archives and NAOI information. A comparison with extensive flood events recorded afterwards and that have affected the South of France and Spain (1907, 1982, 1992, and 1999) has been made. The synoptic meteorological situation has been analyzed with special emphasis in the orographic role.
