Sandbag
- Sandbag may refer to a Nintendo character, Sandbag
A sandbag is typically used in flood control, but the exact use can vary.
Sandbags are burlap bags filled with sand, in an amount that a person can carry from where it's made, to where it will be used. The use most people are familiar with is during emergencies, when rivers are threatening to flood outside their normal channel, or if a dike is damaged. However, sandbags often are used in non-emergency situations (or after the emergency has passed) as the foundation for new, or higher dikes, or other water-control structures.
