WebbWe recognize four major examples: Grain flows Fluidized sediment flows Debris flows Turbidity currents Cohesionless grain flow at False Cape State Park, VA Grain flows: Cohesionless grains flow downhill under the force of gravity. Fluids (air or water) trapped between grains acts as a lubricant, but unlike in stream flow, doesn't propel the grains. WebbDepositional systems in deep-water basin margins can be classified on the basis of grain size and feeder system into 12 classes: mud-rich, mud/sand-rich, sand-rich, and gravel-rich "point-source submarine fans;" mud-rich, mud/sand-rich, sand-rich, and gravel-rich "multiple-source submarine ramps;" and mud-rich, mud/sand-rich, sand-rich, and gravel-rich "linear …

WebbThere are four main types of sediment gravity flows, in increasing order of importance: Grain flows occur when the sediment is supported and moved by direct grain to grain interactions. Examples include downslope sand movement in submarine canyons that result in well-sorted sands or gravels deposited in channels of submarine fans.

Webba. The angle of repose is about 30 degrees. b. The angle of repose is the minimum angle at which a slope is stable. c. The angle of repose is used to refer to bedrock or unconsolidated sediment. d. The angle of repose varies depending on the grain size and shape of the sediment.

WebbLandslides can occur as flows, slides, or rockfalls and topples. A major difference between the three types is the amount of water—flows have the most and rockfalls usually have the least. FLOWS Flows are generally a slurry mixture of water, soil, rock and (or) debris that moves rapidly downslope. Flows may or may not be confined to a channel.
