Abstract:

This paper studies nonlinear amplification of seismic ground motion by alluvial valley in layered sites. The equivalent linear method is used in dynamic analysis and transmitting boundaries are added at boundaries of the computation region. It is shown that, soil nonlinearity has significant effect on seismic ground motion around alluvial valley. The amplitudes in the case of linear alluvium and soil layers are the largest, those in the case of nonlinear alluvium and soil layers are the smallest, and those in the case of nonlinear alluvium and linear soil layers fall in between.

Abstract:

Alluvial parent material soil is an important soil type found on the Qinghai–Tibet Plateau (QTP) in China. However, due to the limited age data for alluvial soils, the relationship between alluvial geomorphological processes and soil pedogenic processes remains unclear. In this study, three representative alluvial parent material profiles on the Buha River alluvial plain in the Qinghai Lake Basin, northeast QTP, were analyzed using the optical luminescence (OSL) dating method. Combined with physical and chemical analyses of the soil, we further analyzed the pedogenic process of alluvial soil.

The humus content in alluvial granular-layered and meadow-marsh soils is much lower. The active reaction of these soils is neutral or slightly acidic, since the river and groundwater of the Insar floodplain are medium mineralized and belong to the class of bicarbonate.

Abstract:

AbstractLarge-scale river regulation, drainage and intense farming in the Barycz valley initiated in 17th century activated a transformation of the initial alluvial and swamp-alluvial soils. Soils on the Holocene flooded terraces have deep, acid humus horizons (umbric) and gleyic properties at shallow depth, but have no stratification of parent material to a depth of 100 cm. Despite the location in the floodplain, soils cannot be classified as black-earth alluvial soils (mady czarnoziemne) using the criteria of Polish soil classification (2011). The soils on the Pleistocene non-flooded terrace

Abstract:

The distribution of total and available copper and their relationship to different soil properties were studied in twenty three soil profiles representing seven major soil series of Namakkal Taluk in Tamil Nadu. The total copper content varied from 12.6 to 105.5 ppm and increased with depth. Laterite soils contained more of total copper than black, alluvial and red soils and the total copper was closely related to available copper, clay, silt, calcium carbonate, fine and coarse sand. The available copper content varied from 0.20 to 1.13 ppm and the content showed an irregular distribution with

Abstract:

Knowledge of soil–landform relationships helps in understanding the dominant pedogenic processes causing variations in soil properties within and between landforms. In this study, we investigated how major pedogenic processes in three landform positions of the semi-arid Deccan Plateau (India) have led to current plant yield-limiting soil properties. For this, we characterised 26 pedons from three landforms – piedmont, alluvial plain and valley – and performed factor analysis on the dataset. As the frequency distribution of the dataset was highly skewed for most of the soil properties, landform

Alluvial-meadow soils develop under the meadow soil with forb-cereal groups and shrub vegetation under the active influence of groundwater occurring at a depth of 1.0–3.5 and surface (flood) moisture.

Alluvial soil formation is a dynamic process, the main prerequisite of which is the regular, periodic flooding of the river floodplain with flood waters, which are enriched with multidispersed organic and mineral particles. During the last century, about 80 % of territory of the Upper-Dniester alluvial plain was transformed by means of hydrotechnical construction: waterproof dams and drainage channels have broken the wide river floodplains into isolated fragments, making impossible the free flow of flood waters, enriched with silt.

This paper presents the liquefaction potential of densely populated Kolkata city, which is situated on the world's largest delta island with very soft and thick alluvial soil deposits. Due to presence of soft alluvium deposits at shallow depths, soil resistance against liquefaction is expected to be less. Additionally, large thickness of soil layers may amplify the ground shaking resulting in high seismic demand on the soil. Here in this study, variation of factor of safety against liquefaction is evaluated with depth at different locations in Kolkota city. The study founds striking results th

When growing wheat on reclaimed alluvial turf heavy loamy soil, the toxic effect was manifested only in the early stages of plant development in a variant containing 16.9 g/kg of PP.

As a result of the soil improvement made with the CJG, it was observed that there was a decrease in settlement, permeability, and liquefaction potential and an increase in the bearing capacity. In this study, columns with different grouting pressures (400, 450, and 500 bar) and water/cement ratios of 0.75, 1.00, and 1.25 were produced on several soil types (sand, clay, and alluvial soil) that have high liquefaction, settlement potential, and low bearing capacity.

The red soil exhibited acute toxicity even at lower concentration and the LD 50 of these herbicides were lower than the alluvial and black soils.

Pollen in surface soils is deposited by wind; pollen grains in alluvium are deposited by a stream as sedimentary particles. Clay-size particles correlate significantly with Pinus, Quercus, and Populus pollen. These pollen types settle, as clay does, in sl
