The erosion of visco-plastic cohesive soils under the action of a turbulent fluid flow is studied. The equations describing a sediment bed are discussed. To solve them, the density distribution in the bed must be known at some initial time. Experimental field studies and results from the ultracentrifuge provide a clear picture of the density ...

Journal of Hydraulic Research, 1984
Experiments on erosion of cohesive soils using a circular couette flow erosion device and three clays with eight electrolytes (solutions) at approximately constant temperature are described. The analysis of the experimental results using the erosion model based on the rate process concept shows that the erosion rate of a clay by an electrolyte with ...

Journal of Hydraulic Research, 1976
This study evaluates the effect of some basic properties of clay-minerals mixed with cohesionless soil on scouring at the toe of a spillway. Scouring was analyzed by the concept of incipient motion of the soil particles. Experiment was performed to determine the influence of the clay-minerals (Kaolinites) and its compactness on the rate of volume of ...

Soil cohesion is disrupted by tillage, ice lenses formed during freezing, and differential swelling and air entrapment during rapid wetting. These disruptive events are generally followed by periods during which new bonds form quickly if the soil is wet and dries so that soil-water tension and interfacial tension pull the particles into direct contact.

1. Experiments in which were measured the resistances to (a) transverse breaking, (b) crushing, and (c) parting under tensile pull of standard blocks of soil prepared in different ways and under particular moisture conditions are described and discussed.2. The soils examined comprised three highly colloidal siliceous soils containing amounts of calcium

1. A physical substantiation of the dimensionless group Mr as a parameter of the resistance of the channel to erosion is given and other dimensionless groups (the flow-channel system) are included in it. 2. New dimensionless groups (6)-(9), which are a development of the Lokhtin-Velikanov idea about the law of interaction of the flow and

Liquefaction of Cohesive Soils
Soil Dynamics and Liquefaction 2000, 2000Liquefaction of sand, clean or with some fines content, has been extensively studied over the last three decades and is currently a phenomenon reasonably predictable. The study of cohesive soils behavior during and immediately after cyclic loading is especially difficult because of their structure variability and the major influence of structural ...

Fractal Representation of Soil Cohesion
Journal of Geotechnical and Geoenvironmental Engineering, 1999Evaluation of soil cohesion is usually based on measurements made on laboratory-scale samples. Some previous studies point out a decreasing trend in cohesion as the test specimen size increases. Although this trend is, in general, attributed qualitatively to fractures and macropores associated with larger samples, no rational basis has been put forth ...
