Flood protection is an important measure taken to protect people and property from the destructive effects of flooding. Sandbags are commonly used to divert or contain floodwaters, and are filled with sand or soil and placed in strategic locations. A POLICY is a set of rules or guidelines that are established to help manage a situation, and in this case, it would be a POLICY to help protect against floods. A LEVEE is an embankment built along the banks of a river to prevent flooding, while a DYKE is a similar structure built in coastal areas to protect against flooding from the sea. Together, these measures can help protect against the devastating effects of flooding.
