Most flows are liquefied, and many references to fluidized sediment gravity flows are in fact incorrect and actually refer to liquefied flows. [5] Debris flow or mudflow – Grains are supported by the strength and buoyancy of the matrix. Mudflows and debris flows have cohesive strength, which makes their behavior difficult to predict using the ...

A massive debris flow has brought a long-term closure to the Valley of the Giants, a popular hike through some of Oregon’s oldest and largest trees in the Coast Range.. In early December 2023 ...
Large masses of material are moved in debris flows, hyperconcentrated mixtures of mud, clasts that range up to boulder-size, and water. Debris flows move as granular flows down steep mountain valleys and washes. Because they transport sediment as a granular mixture, their transport mechanisms and capacities scale differently from those of ...
Rio Huitzilapan debris flows est. 600–870 Debris flows destroyed village of Barranca Grande, and were 40 to 65 m (131 to 213 ft) deep. Debris flows extended >40 km (25 mi). Triggered by M~6.5 earthquake. [69] 1921 Almaty, Kazakhstan: Alma-Ata Debris Flows ~500 A debris flow in the Valley of Alma-Atinka River destroyed the town of Alma-Ata. [69]
