floodgates

Floodgates are large barriers installed across rivers or waterways to control water flow. They can be opened or closed to manage water levels, prevent flooding during heavy rains, or allow safe passage of boats. Typically made of strong materials like steel or concrete, floodgates help protect communities and ecosystems by regulating water flow, especially in flood-prone areas. They are vital components of flood defense systems, providing a controlled response to changing water conditions to minimize damage and maintain safety.
