What are two kinds of barriers people use to protect themself from floodwater?

Two common types of barriers used to protect against floodwaters are levees and floodwalls. Levees are earthen embankments that help redirect water away from vulnerable areas, while floodwalls are typically made of concrete and provide a more robust barrier against rising waters. Both structures are designed to minimize the impact of flooding on communities and infrastructure. Additionally, temporary barriers like sandbags can be used for quick protection during emergencies.
