A mudflow, also known as mudslide or mud flow, is a form of mass wasting involving fast-moving flow of debris and dirt that has become liquified by the addition of water. [1] Such flows can move at speeds ranging from 3 meters/minute to 5 meters/second. [2]

*Mudflow is defined as, “A river of liquid and flowing mud on the surface of normally dry land areas, as when earth is carried by a current of water. Other earth movements, such as landslide, slope failure, or a saturated soil mass moving by liquidity down a slope, are not mudflows.”

Mudflow, flow of water that contains large amounts of suspended particles and silt. It has a higher density and viscosity than a streamflow and can deposit only the coarsest part of its load; this causes irreversible sediment entrainment.

Debris and mud flows are a combination of fast moving water and a great volume of sediment and debris that surges down a slope with tremendous force. The consistency is similar to pancake batter. They are similar to flash floods and may occur suddenly without time for adequate warning.

A mudflow is a rapid flow of water-saturated soil and debris down a slope, often triggered by heavy rainfall or earthquakes. Mudflows, also known as debris flows, are fascinating yet destructive phenomena that occur when water-soaked earth materials move rapidly down slopes.

A mudflow is a river of liquid, flowing mud on land that is normally dry. The earth is carried by a current of water. Wildfires destroy plants and trees that strengthen hills—and char the soil so it can’t absorb rainfall. This increases risks for flash floods and mudflows. Rainfall across burned areas washes soil downslope.

A mudflow is a rapid flow of viscous fluid containing water and plastic debris, typically formed from clay or silt, and is similar to an earthflow but with higher water content. You might find these chapters and articles relevant to this topic. P. Santi, ... J. DeGraff.
