A flood can occur even after local rain stops. Water also comes from upstream and moves downstream through the Chari, Logone, Mayo-Kebbi, Tandjile and wetland basins.
As water rises, it reaches low homes, wells, fields and roads.
The current can sweep away a person, motorbike, vehicle, livestock or materials.
Water that remains for several days disrupts health, drinking water, school, trade and food.
A downstream area can be threatened by rainfall that fell far upstream.
