levee breaches
Dike walls collapse
Levee breaches are failures in flood-control embankments that allow water to rush through.
A levee may breach from erosion, overtopping, or structural weakness during high water.
The term gained widespread use during Hurricane Katrina, when multiple breaches flooded New Orleans: The levee breaches turned neighborhoods into lakes overnight.
