## Mudflows

### Definition :

Mudflows behave more like fluid-transported materials than slides. They often result from slide materials mixing with large amounts of water (e.g., from rivers or heavy rain). Characteristics:

- Loose, heterogeneous clay-rich materials

- Triggered by exceeding a critical water content, creating semi-fluid behavior

- Long travel distances and potentially high velocities

### Example :

The Photo shows the 2005 clay-rich mudflow on National Road RN 52 in Mila Province. The catastrophic 2003 Beb El-Oued mudflow remains unforgettable, destroying multiple homes and claiming numerous lives.
