Flow movement geology
WebA debris flow is a moving mass of loose mud, sand, soil, rock, water and air that travels down a slope under the influence of gravity. To be considered a debris flow, the moving material must be loose and capable of "flow," … WebJun 8, 2024 · Flows are rapidly moving mass-wasting events in which the loose material is typically mixed with abundant water, creating long runouts at the slope base. Flows are commonly separated into debris flow (coarse material) and earthflow (fine material) depending on the type of material involved and the amount of water.

WebVarieties of these are called earthflows, mudflows, and debris avalanches. When earth material moves down a hillside as a fluidlike mass, it is called an earthflow. These flows typically occur in humid areas on steep slopes with thick, clay‐rich soil that becomes saturated with water during storms.

Webtle or no water to flow in or out. A forma-tion that acts as such a water barrier is called aquitard if it is much less permeable than a nearby aquifer but still permits flow (e.g., sandy clay). If the water barrier is almost impermeable (e.g., clay) and forms a formidable flow barrier between aquifers, it is known as anaquiclude. Weblandslides.
