annual floods
Yearly river overflows
Annual floods are seasonal flooding events that occur predictably each year, typically when rivers overflow their banks during periods of heavy rainfall or snowmelt.
Many agricultural systems historically depended on annual floods to deposit nutrient-rich sediment on farmland: The Nile's annual floods sustained Egyptian civilization for millennia.
The term also appears in insurance and urban planning contexts, where annual flood risk determines building codes and coverage rates.
