Flood protection refers to various methods and structures designed to prevent or reduce the impact of flooding on communities and infrastructure. This can include levees, which are raised banks along rivers, and floodwalls, which are solid barriers that block water. Other measures include floodplain zoning, where development is restricted in high-risk areas, and the construction of retention basins that temporarily hold excess rainwater. In addition to physical structures, flood protection also involves early warning systems that alert residents to impending floods. These systems use technology to monitor weather patterns and water levels, allowing communities to prepare and respond effectively. Overall, flood protection aims to safeguard lives, property, and the environment from the damaging effects of floods.
