Why is a levee only a temporary solution to flooding?

A levee is only a temporary solution to flooding because it primarily serves as a barrier to redirect water rather than addressing the underlying causes of flooding, such as increased rainfall, rising sea levels, or land subsidence. Over time, levees can be overtopped, breached, or weakened by erosion, sediment accumulation, or structural failure. Additionally, reliance on levees may encourage development in flood-prone areas, increasing vulnerability when extreme weather events occur. Sustainable flood management requires a combination of strategies, including natural solutions, improved land use planning, and floodplain restoration.
