  abstract = {{R}iver flooding has large societal and economic impacts across {A}frica. {D}espite the importance of this topic, little is known about the main flood generating mechanisms in {A}frica. {T}his study is based on 13,815 flood events that occurred between 1981 and 2018 in 529 catchments. {T}hese flood events are classified to identify the different flood drivers: excess rains, long rains and short rains. {O}ut of them, excess rains on saturated soils in {W}estern {A}frica, and long rains for catchments in {N}orthern and {S}outhern {A}frica, are the two dominant mechanisms, contributing to more than 75% of all flood events. {T}he aridity index is strongly related to the spatial repartition of the different flood generating processes showing the climatic controls on floods. {F}ew significant changes were detected in the relative importance of these drivers over time, but the rather short time series available prevent a robust assessment of flood driver changes in most catchments. {T}he major implication of these results is to underline the importance of soil moisture dynamics, in addition to rainfall, to analyze the evolution of flood hazards in {A}frica.},
