Περιβάλλοντα αποθέσεως των ιζημάτων του Πηδάσου (Ν.Δ. Πελοπόννησος)
… to be carried out. The lower beds are sandy and clayey silts interbedded with conglomerate and are probably alluvial fan deposits. Overlying is a sei sequence of marine faciès, mostly deposited in a lagoon. Silty sand and clayey silt were probably built up in lagoonal euxinic bottom. …

Seismic induced flow deformation and remediation study of Sardis Dam
… of Sardis Dam indicated that the entire central silt core and a weak clayey silt layer in the dam foundation are susceptible to liquefaction which could result in large losses of shear strengths in these liquefied soils. The post-liquefaction behaviour of Sardis Dam was evaluated using new flow …

Distribution of ammonium nitrate as nitrogen containing nutrient for in-situ biodegradation by means of electrokinetics
… for in-situ bioremediation in a natural clayey silt was investigated. Three different concentrations of ammonium nitrate solution were used. The experiment showed the efficiency of the electrokinetic method for supplying nutrients in a low permeability soil, especially for distribution of …

Late Pleistocene and Holocene geology of the Moe Site, New Town, North Dakota
… consists of light yellowish brown, offshore lake silt that was deposited into a glacial lake in Late Wisconsinan time. Unit Three is a layer of glacial sediment consisting of grayish brown pebbly clay loam (Late Wisconsinan). Unit Four consists of fluvial sand and gravel (Late Wisconsinan}. Unit …

Paleoenvironmental reconstruction of late quaternary lacustrine sediments (Seibold Site) in southeastern North Dakota
… in ascending order, is a follows: 1) pebbly silt; 2) clayey silt; 3) organic mud; 4) calcareous mud; 5) sandy silt and clay; 6) silty sand; and 7) sandy silt and clay.</p> <p>The stratigraphic sequence and biota suggest a 5-phase history for the area during the last 11,000 years. During phase …

Exact reconstruction of ocean bottom velocity profiles from monochromatic scattering data
… of bound states is shown to be justified in both clayey silt and silty clay at the 220 Hz frequency of operation. Three methods for the numerical solution of the integral equation are investigated. The first one is an "Improved Born approximation" wherein the solution is given as a series …

Influencia de la combinación de tensiones tangenciales estáticas y cíclicas en la evaluación de parámetros dinámicos de un suelo cohesivo
… characterized by the presence of interlayered clayey silt, silty clay and some lenses of fine-grained micaceous sand. To perform this investigation only the samples of clayey silt and/or silty clay were used. Based on the results of the experimental phase the influence of combined static and …

Glacial geology and stratigraphy of southeastern Pierce and southwestern Benson counties, North Dakota
… <p>The Oahe Formation consists of fine sand, silty clay, and organic-rich clay; it is most common in abandoned river channels and in depressions.</p> <p>Although most previous studies have interpreted the surface till to be the result of supraglacial processes (ablation), the till fabric data …

Meaning, measurement, and field application of fully softened shear strength of stiff clays and clay shales
… to stiff clays, clay shales, mudstones, marls, clayey silt, and glacial clays, using the observed slip surface or possible slip surface determined based on adequate field observations, together with the observed or assumed groundwater pressure conditions reported in the original references. In …

Engineering properties and behavior of silty soils
Silty soils, which exhibit engineering behavior intermediate between sands and clays, pose persistent challenges in geotechnical engineering due to their variable fabric, partial drainage behavior, and difficulty in classification and sampling. This dissertation presents a comprehensive …

Análisis, modelización e implementación Numérica del comportamiento de suelos Blandos ante la combinación de tensiones Tangenciales estáticas y cíclicas
… characterized by the presence of interlayered clayey silt and silty clay. The results indicate that depending of the combination of static and cyclic shear stress, which are similar to certain conditions of pressure under the foundation level of structures, some elements of the same cohesive …

Quaternary geology of Sargent County, North Dakota
… sand and gravel (fluvial channel sediment); silt (lacustrine sediment); silty clay (lacustrine sediment); and silt, sand, silty sand, and clay (turbidity-current sediment). </p><p> The Walsh Formation comprises the remaining 5 percent of the county and includes four facies: clay (lacustrine …
