Floods - tmpx Print

Flooding has existed since water first appeared on earth. They are daily and not only destructive. Like those of the Nile which deposited silt every year to fertilize the flooded lands. Or those of rice fields for growing rice. The origins of floods are naturally created by various phenomena such as hurricanes, tidal waves, storms, thunderstorms, rising water
tables, ruptures of natural dams ... As this was not enough, we can add to this non-exhaustive list, the land use of humans. The man does his best, but sometimes has bad agricultural practices, urbanization impermeable to bad weather, constructions in flood zones and especially bad management for the
evacuation of water in the event of big storms ... Flooding is one of the main natural hazards in the world; it is the natural disaster causing the most damage. For the period 1996-2005, approximately 80% of the world's natural disasters were of meteorological or hydrological origin. Floods reportedly affected an average of 66 million people per year between 1973 and 1997
