WebA comparison with Lowe's (1979) classification, for example, shows that (low-density) turbidity current and cohesive debris flow correlate quite well (because the steady-flow state is not much different from their ultimate rheological state), but that liquefied flow, fluidized flow, grain flow, and modified grain flow all belong to the same ... Webcohesion is zero and the shear strength is defined solely by the friction angle. The friction angle of the rock material is related to the size and shape of the grains exposed on the …

WebFault gouge is a type of fault rock best defined by its grain size. It is found as incohesive fault rock (rock which can be broken into its component granules at the present outcrop, only aided with fingers/pen-knife), with … WebMudflows and debris flows have cohesive strength, which makes their behavior difficult to predict using the laws of physics. As such, these flows exhibit non-Newtonian behavior. Because mudflows and debris flows have cohesive strength, unusually large clasts may be able to literally float on top of the mud matrix within the flow.

WebErosion, driven by gravity, is the inevitable response to that uplift, and various types of erosion, including mass wasting, have created slopes in the uplifted regions. Slope stability is ultimately determined by two factors: the angle of the slope and the strength of the materials on it. In Figure 15.2 a block of rock situated on a rock slope ... WebCOHESIVE DEBRIS FLOWS (MORE THAN 3 TO 5 PERCENT CLAY) The largest lahars at Mount Rainier were recognized as relatively clay-rich by Crandell (1971), who logically hypothesized that a clay content of about 5 percent or more reflected an origin directly from large landslides. The clay is an alteration product of the hydrothermal system of the ...
