Floods are the most frequent hydrometeorological events in Uruguay, caused by various phenomena.
Sudestadas: Associated with winds blowing from the south of the Río de la Plata towards the coast, these types of weather events cause increases in the river level and water inflows in the city. Coastal localities are frequently impacted by these situations.
Riverbank floods: These occur when rivers or streams overflow, either by filling their beds or by advancing towards flood plains. Urbanization is directly linked to these floods, where river floods collide with built-up areas on flood plains.
Floods due to failures of protection works: Related to levee or dam failures, these floods affect cities located downstream of such works.
