This map shows the relation between the season and the number of floods (max. during the North summer, Jul/Aug) and the importance of Asian floods on the total. It also shows the relation between the season and the movement of floods in latitude. For example:

  • The concentration of the floods at the low latitudes in the North Hemisphere during the summer (Aug/Sep)

  • The development of the floods in the South hemisphere during the winter (from Dec to Apr/May).

Flood events are probably underrepresented on the northern part of the world (North Russia and North Canada) because as they concern few people, they don't necessarily appear in the news reports. Among the different results, it is interesting to notice the importance of dam (or levy) break (or release) in the southern hemisphere, or the tremendous impact of monsoonal rain on the Ganges, Brahmaputra watershed. On this map main cause and secondary causes are represented, which explain why some floods have 2 different causes.

The long average flood duration in January comes from a high number of long floods (> 21 days) in the Southern hemisphere. In April the average duration is also pretty high, but the long duration floods are scattered all over the world. In July this long duration floods are concentrated in South-East Asia. And in August these monsoonal floods are completed by some African ones (in the Northern Hemisphere of the continent).
