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. The periods in the case of nonlinear alluvium and soil layers are the longest, those in the case of nonlinear alluvium and soil layers and those in the case of linear alluvium and linear soil layers are almost the same.

Abstract. Soils vary spatially due to differences in soil management and soil formation factors. The soil spatial variability is an important determinant of efficiency of farm inputs and yield. This study was carried out to identify and compare spatial variation of some soil physical properties by geostatistics in alluvial and adjacent colluvial soils formed under ustic moisture regime at Gökhöyük State Farm (1750 ha), Amasya, Turkey. Seventy four soil samples were collected on a regular grid (500 × 500-m) and additional 224 samples were collected on 28 500-m fine-transects, randomly superimposed between the nodes of grids. Semivariograms and corresponding kriging maps for soil texture, soil organic matter (SOM), bulk density (BD), saturated hydraulic conductivity (Ks), and available water content (AWC) were prepared. Statistical analyses were conducted separately for colluvial and alluvial sites as well as whole area. The soils in alluvial site is rich in clay with high BD and SOM, and low in Ks and AWC; and the soils in colluvial site was designated as low in Ks, SOM, and AWC and high in BD. All variables, except SOM, showed a strong spatial dependency. In general, nugget, sill and range values of most of the studied soil variables decreased from alluvial site to colluvial site. When local (alluvial and colluvial sites separately) and global (alluvial + colluvial) kriged maps for BD, AWC, and soil textural separates, use of global semivariograms (one semivariogram for entire study area) resulted in lost of some details in colluvial sites, suggesting that local semivariograms for alluvial and colluvial soils should be used in kriging predictions at the farm. The results had significant implications for water management as AWC was spatially associated to clay content in alluvial site and to clay and sand contents in colluvial site.

Abstract:
The article is based on a long-term study of floodplain soils of the Amur River valley within the north-eastern part of the Middle-Amur Lowland. The results of field work on the soil-geomorphological profile across the Slavyansky Island, located 200 km from Khabarovsk down the Amur River, are discussed. The study analyzes the occurrence of the island's floodplain soils on riolkas[1] and their properties, with an emphasis on morphology and lithological and particle-size composition. The features of soil formation on riolkas of different genesis – alluvial and aeolian – are shown. On sandy and sandy-loam deposits of alluvial riolkas (“meadow-forest” ridges) poorly developed sod gley soils are formed. On heavy loam and clay alluvium of the “meadow“ ridges, annually flooded by river waters, sod-meadow gley soils develop under the woodreed grass stand. Sand deposits of high aeolian riolkas are characterized by a homogeneous fine-grained structure without interlayers, signs of organic matter and with a significant amount of mica. They describe poorly developed sod-forest soils under high-trunk oak forests. The formation of texture-differentiated soils on all types of riolkas was not revealed. When the floodplain reaches the position of the first terrace above the floodplain, the differences in the lithological composition and particle-size distribution, soil texture, height above the water edge and the nature of vegetation on the inherited riolkas provide a multidirectional evolution of soil formation. At the same time, the development is taking place in accordance with the zonal types of soils (sod-forest, brown-earth, texture-differentiated – soil with a bleached horizon (podbel)). The last are mainly formed on clay-loam alluvium, which can overlay not only alluvial, but also some aeolian riolkas. [1]Riolkas are ancient, relatively high sand ridges (extended dunes) with plant cover found in Amur region (Russian Far East).

Abstract:
This work was carried out to study the content and distribution of available for plants phosphorus in different types of floodplain soils along five catenas located in the upper and the middle Amur. It was found that the available for plants phosphorus forms in the soils of floodplains are influenced by the following factors: the structure of the river system, the type of floodplain, the type of vegetation cover, and soil-forming processes. During the long-term transportation of alluvium along the river bed, its hydrogenic weathering occurs with the release of phosphorus into river waters. In the absence of tributaries serving as additional sources of alluvium, the phosphorus content decreases downstream. More intense floodplain and alluvial processes in small floodplains provide renewal of the soil profile and replenishment of phosphorus reserves. In the soils under the birch forest, there is a significant accumulation of phosphorus, in comparison with the soils under meadow vegetation. The development of gley processes leads to active mobilization of phosphorus, but the long-term exposure leads to the depletion of its total reserves. The illimerization processes, initiated and developing when the floodplain hydrological regime of alluvial soils is changed to another one, promote the migration of iron oxides and phosphorus, adsorbed by the former, beyond the soil profile. To summarize, the average content of available for plants phosphorus, depending on the type of soil, decreases downstream from 300–100 mg/kg in the upper Amur to 170–20 mg/kg in the middle Amur. Available for plants of phosphorus are best provided in primitive alluvial layered soils, while in residual floodplain brunezems the lowest content is recorded.

Abstract:
To provide a simple and fast alternative in measuring soil water content (SWC), a spectrometer was used to detect SWC because of different soil water contents, leading to different reflectance spectrums. Two commonly seen soil types in Taiwan are red soil and younger alluvial soil, which were used as test materials in this study. Fifty red soil samples and 50 younger alluvial soil samples were used as testing samples for comparative study. The root mean square error of SWC estimation of red soil and younger alluvial soil is 3.65 and 7.26, respectively. The results show that the estimation accuracy of red soil is higher than that of younger alluvial soil. The estimation error is random for red soil, and decreases exponentially for younger alluvial soil. Spectrometers have the potential to detect soil water content, especially in red soil. After full development of this technology, remote sensing will be applied to detect soil water content or even water-induced landslides.

Abstract:
Studies show that the most fertile are the granular soils of the Central floodplain of the Insar river. They have high humus content in the upper horizons – 4.6-7.6 %. Down the profile, the humus content gradually decreases, but remains relatively high: at a depth of 60-70 cm – 4.0 %. 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. The hydrolytic acidity of the alluvial granular soil of the Insar floodplain is 1.6-3.0 mg / 100 g of soil. The values of hydrolytic acidity of alluvial granular-layered and meadow-marsh soils are higher: 2.6-3.6 and 1.8–3.2 mg/100 g of soil, respectively. The studied alluvial soils are almost completely saturated with bases: 91-97 %. The studied alluvial granular soils of the Insar floodplain are characterized by an average content of available phosphorus. In granular-layered and meadow-marsh soils, the amount of this element is slightly less and is 7.0–5.1 and 7.4–5.4 mg/100 g of soil, respectively. The most potassium-rich alluvial granular soil in the floodplain of the Insar river, where the content of this element in the upper layers is characterized as high: 16.5–27.6 mg/100 g of soil. In the sod layer of granular-layered soil, potassium availability is average: 9.5-15.4 mg / 100 g of soil. In the turf layer of meadow-marsh soils, potassium content is observed for most crops (8.0-10.4 mg / 100 g of soil), with depth it decreases.

Abstract:
The use of microorganisms and organic materials in agriculture because it can increase the availability of soil nutrients and absorption by plants and form soil structures becomes looser. The purpose of this study was to obtain the most effective types of decomposer microorganisms and the most appropriate organic fertilizer (compost) to improve the physical, chemical and biological properties of alluvial soils and their role in plants in cocoa seedlings. The research was conducted in the Laboratory of Soil, Greenhouses and experimental gardens of the Agricultural Polytechnic State Payakumbuh Tanjung Pati Kabupaten Lima Puluh Kota. The study uses experimental methods. The study used a factorial randomized block design on soil tests and a complete randomized design for the cacao seedling test. Parameters observed were alluvial soil pH, N-total alluvial soil, P-available alluvial soil, K-exchangeable alluvial soil, alluvial soil volume weight, the total population of alluvial soil bacteria, plant height of cocoa seedlings, number of leaves of cocoa seedlings, stem diameter of cocoa seedlings, dry weight of cacao seed stover. The results of the study there were no differences in the treatment of the type of compost and the type of microorganisms to the pH value of the soil. Types of microorganisms with the type of compost can increase the total N content in alluvial soil. The use of compost types and types of microorganisms had a significantly different effect on the value of soil volume weight, P-available, K-exchangeable, and the total population of alluvial soil bacteria. Treatment of Type of Compost Tithonia and Types of Pseudomonas fluorescens + Trichoderma harzianum microorganisms have the best influence on soil test variables. The application of cacao seedlings at the dose of Tithonia compost 1.25 kg/polybag provides the best growth. Keywords: Alluvial soil, cocoa seedlings, compost, microorganisms

The weed flora growing stubble-fields area is determined by soil features. Weeds found in cereal stubble-fields on black soils formed from sands and loams, medium and haevy alluvial soils as well as brown and chernozem rendzina soils are presented in the paper. The 273 phytosociological records were worked out. They were collected from 87 stands situated in 76 localities of Kielce region. The results showed that species number and species composition were dependent on the soils (black. alluvial, rendzina). The existance of 118 (medium alluvial soil) to 140 (brown rendzina soil) weed species, including 73 common for all of the soils considered, was found there. Relatively high per cent (29-35) of them belonged to perennial weeds. From 22 (brown rendzina soil) to 35 (heavy alluvial soil) of species reached high constancy degrees (V-III). <i>Stellaria media, Myosotis arvensis, Polygonum aviculare, Agropyron repens</i> and <i>Cirsium arvense</i> predominated on the all of the soil examined. Among the weed flora registered, 25 species, recorded only on rendzina soils, were distinguishable for that soils.

Abstract:
The Wagga Wagga 1 : 100 000 map sheet is on the Western Slopes of southern New South Wales. The regional topography changes from hills in the east and south-east to gently sloping rises and alluvial plains in the west. Aeolian clays (parna) form a consistent clay regolith regardless of the underlying geology in the gently sloping areas. In some alluvial plains and on some lower hill slopes, the surficial sediments contain a significant portion of reworked parna. In hilly areas, parna is poorly preserved except on some remnant ancient land surfaces, such as dissected plateaux and piedmont plains. The soil pattern in the area is well controlled by landform processes and history. On relatively steep hill slopes, locally derived materials from weathering of bedrock are usually the dominant components of the soils, and geology is the dominant factor controlling soil distribution. In contrast, the Murrumbidgee high floodplain is covered by uniform silty clay with deep clayey soils (brown/grey Dermosols). Before the mid-Holocene, the alluvium mainly comprised sands and gravels, which were reworked by wind forming sand sheets and sand mounds (source-bordering dunes) on which deep sandy soils (Rudosols) now occur. The sediments and soils on the alluvial plains of local streams vary according to their distance from the source area and the flooding frequency. Areas considered to be mantled by parna, uniform red clayey soils (haplic red Kandosols/Chromosols) occur. Although the distribution pattern of the soils is controlled by the landform evolution, the relationships between soil morphological properties and topography are not readily quantified. On the alluvial and gently sloping landforms, soil properties usually show little change even though slope gradient and slope length vary. Some soils, e.g. the Rudosols on the sand sheets, rarely show any topographic features which may indicate their presence. In limited areas, e.g. on steeper hills formed on metasedimentary rock, the soil properties vary with changes in topographic parameters (slope gradient and slope length).

Abstract:
A modified plate load (MPL) test was developed to measure the in situ cohesion of a carbonate or caliche cemented soil. The MPL test was performed on the crest of a vertical cut in alluvial soil with a steel plate loaded until the soil failed. A three-dimensional slope stability analysis was then used to back calculate soil cohesion. In situ test results were used in conjunction with laboratory testing of deaggregated soils samples to completely define the Mohr-Coulomb strength parameters of the in situ soil. In order to check the result of the in situ test procedure, the field test conditions were modeled for use in a two-dimensional slope stability analysis using the computer program CSLIP1. A comparison of the results shows reasonable values of soil cohesion were obtained using the MPL test method.

Abstract:

Because the Coastal Plain of southeastern Virginia has not been extensively studied, thirty random samples associated with Blackwater and Nottoway rivers were collected in the spring of 1987 from Surry, Sussex, and Southampton counties. Soil classification as well as mineralogical, chemical, and physical analysis were conducted for all samples.

The purposes of this investigation were to: (1)classify the soils in this area, (2) determine the distribution of sand and clay minerals, (3) examine the weathering effect on clay minerals on different position of the landscape for different parent material sources.

The soils examined classified as follow: Aquic Hapludults 43% > Typic Hapludults 26.6% > Ultic Hapludalfs 10% > Humic Hapludults 3% = Typic Rhodudlts 3% = Aquic Hapludalfs 3% = Typic Udipsamment 3% = Typic Quartzpsamment 3% = Psammentic Hapludalfs. Qualitative analysis of clay minerals revealed that kaolinite and hydroxy interlayer vermiculite were the dominant clay minerals; that montmorillonite, mica, gibbsite quartz, and vermiculite were of lesser quantities; that chlorite, feldspar and interstratified minerals were of trace amounts. Kaolinite represents about 21-70%, HlV 11-60%, montmorillonite 0-20%, mica 0-16%, gibbsite 0-13%, quartz 1-12%, and vermiculite 0-10%. The presence of these minerals were mainly related to the acid reaction of the soil media, which was essentially attributed to Al and H ions in soil solution. From the past history and geological composition of the Piedmont it is assumed that kaolinitic minerals were transported and sedimented in the Coastal Plain. Hydroxy-interlayer vermiculite minerals was weathering from vermiculite because most of the Al was adsorbed by vermiculite to form HIV. Therfore, gibbsite was not precipitated. Montmorillonite was assumed to have formed from mica minerals. That was substantiated by statistical analysis which showed a high negative correlation between gibbsite and vermiculite (r=0.46, n=30) and between montmorillonite and mica (r=-0.6, n=10).

Full text
Abstract:
Silica cemented pedogenic horizons known as duripans occur on relict landforms in climates having limited leaching potential. Under the influence of tephra, incipient silica cementation may also occur in late Quaternary soils. The source of silica for cementation in Holocene soils is rapidly weatherable volcanic glass. In response to wetting and drying cycles volcanic glass weathers to form sand-size composite particles composed of silt, clay and redeposited silica. A portion of the hydrolyzed silica is eluviated as monosilicic acid which accumulates as the wetting front evaporates. Illuvial silica augments existing composite particles eventually forming a continuously cemented duripan. In actively forming late Quaternary soils, the cementation process is a complex interaction between illuvial silica, clay and calcium carbonate and the soil matrix. Surface reactions between monosilicic acid and illuvial clay or soil matrix particles provide nucleation sites for polymerization of silica concentrated by evaporation. The resulting opaline silica bonds adjacent soil grains without necessarily plugging intervening pore spaces. In contrast, calcium carbonate preferentially precipitates in large pores and interped voids. Cementation occurs by the plugging of progressively smaller pores with relatively pure calcite rather than by heterogeneous bonding of mineral grains. In illuvial zones containing both silica and calcium carbonate, cementation may occur rapidly because the former holds small soil particles in place while the latter plugs large pores. The mineralogy of silica cement is determined by identification of varying amounts of crystal order using X-ray diffraction. Opal-A is recently polymerized, noncrystalline, highly hydrated silica gel. The more prevalent, partly crystalline opal-CT forms where surface reaction with clays create crystal orientation, where silica gel dehydrates or when silica precipitates from soil solutions having high concentrations.

In geotechnical studies, the dynamic probing light (DPL) turns out to be an alternative method to the Standard Penetration test (SPT) for the determination of soil parameters. The requirement of various regulations for correlating both tests in the same field and not establishing a methodology to carry it out, limits the practical scope of dynamic probing light. Thus, this research presents a correlation methodology between the dynamic probing light (DPL) and the Standard Penetration test (SPT) specifically for sandy soils (SP and SP-SM) located in an area of Chilca, located in Cañete. - Lima Peru. For the analysis, more than 400 data pairs were used, obtaining two linear correlations between the count blow of Standard Penetration-NSPT test and the dynamic probing light method-N10, which presented an adjustment correlation between 84% and 87 %.

Full text
Abstract:
Stratigraphic records in Middle Park in north-central Colorado provide evidence for the late Quaternary geomorphic and environmental history of a non-glaciated Southern Rocky Mountain basin. Episodes of geomorphic instability apparent in the stratigraphic record coincide with changes in paleoenvironmental records from above 2750 m in north-central Colorado, suggesting that the western Middle Park landscape was sensitive to environmental changes affecting the region over the last ~14,000 years. Tributaries were incised prior to 14.0 ka, but deposits older than 12.0 ka are rare. Upland erosion and incision followed by rapid aggradation in alluvial settings between 12.0 and 11.0 ka coincide with evidence for regional temperatures at or above present, and is interpreted to signal the onset of Holocene summer-wet precipitation. A widespread soil-stratigraphic marker represents a long period of landscape stability between <11.0 and 6.0 ka in upland and alluvial settings. Pedologic evidence from upland settings indicates the expansion of grass and forest cover to lower elevations that today are characterized by sagebrush steppe, probably during a period of increased summer precipitation relative to present. During the late Holocene, episodes of aggradation in alluvial valleys at 6.0-1.0 ka and 0.6-0.2 ka and soil formation in uplands at 5.0-3.5 ka and 2.5-1.0 ka overlap with evidence for cooling at higher elevations. Incision of valley floors documented at 1.0-0.6 ka and during the last few centuries and episodes of erosion in uplands at 3.5-2.5 ka, after 1.0 ka, and within the last few centuries, are roughly synchronous with evidence for warming. Upland and alluvial stratigraphic records are interpreted to indicate that during cool intervals summer precipitation was diminished, resulting in relative hillslope stability and gradual valley bottom aggradation, while pulses in summer precipitation accompanying warmer episodes caused basin-wide geomorphic instability. The recent increasing frequency of geomorphic instability appears to correspond with an increase in sagebrush steppe at the expense of forest and grass cover, interpreted to represent progressive drying during the late Holocene. It stands to reason that future warming, if accompanied by similar patterns in precipitation, will result in continued erosion on a landscape already at a threshold of geomorphic instability.

Full text
Abstract:
Gemlik County is located in the Marmara Region (NW Turkey), which has been affected by destructive earthquakes sourced from North Anatolian Fault System throughout its history. The bulk of the settlement rests on alluvial deposits of the Gemlik pull-apart basin. So, it is vital to investigate the foundation soils in this basin and the response of them to earthquakes. Many earthquake codes were established by the authorities in different countries of the world to estimate the possible ground shaking and seismic loads which may act on buildings. In this study, Turkish Earthquake Code (TEC-1998) and Eurocode-8 (EN-1998) have been utilized. The analyses showed that EN-1998 results in more conservative estimates relative to TEC-1998, in terms of spectral ordinates. The source of difference between TEC-1998 and EN-1998 has been investigated and three possible reasons have been identified. The variation is probably due to the different seismic characteristics of Turkey and Europe, different soil amplification levels defined by the codes, and different soil classification procedures of the codes.

Abstract:
Waste rice in harvested fields and natural seeds in moist-soil wetlands are important foods for waterfowl in the Mississippi Alluvial Valley (MAV). Waste rice declines significantly between harvest and late autumn. I conducted experiments in 19 rice fields in Arkansas and Mississippi during autumns 2003 and 2004 to evaluate the ability of common post-harvest practices to conserve waste rice between harvest and late autumn. Greatest mean abundance of waste rice in late autumn occurred in standing stubble (x&95 = 105 kg/ha; CL = 72.84, 150.16 kg/ha) followed by burned (x&95 = 72 kg/ha; 49.57, 105.81 kg/ha), mowed (x&95 = 67 kg/ha; 46.65, 97.42 kg/ha), rolled (x&95 = 51 kg/ha; 35.54, 73.076 kg/ha), and disked stubble (x&95 = 48 kg/ha; 33.26, 68.41 kg/ha). I recommend leaving stubble or burning fields to create interspersion of stubble and water after flooding. Additionally, I estimated abundance of moist-soil seed in 72 management units on public lands throughout the MAV for autumns 2002-2004. Mean seed abundance was 496 kg/ha (SE = 62). I recommend increased active management of moist-soil wetlands to mitigate decreased availability of waste rice in the MAV.

Abstract:
Low plasticity, high bearing capacity, low settlement, etc. are the preferred properties for most engineering projects. Alluvial soils are problematic soils because of low bearing capacity, high organic matter content, and high void ratio so they do not meet the preferred condition for engineering projects. It has been necessary to improve unsuitable materials to make them acceptable for construction. Fly ash (FA) has earlier been used for stabilizing roads due to its high content of calcium and silicate oxides which give puzzolanic properties and thus high compression strength. In this research, fundamental engineering properties, compaction behaviors of three types of (fine, medium, and coarse) alluvial deposits, and the effect of fly ash on compaction behavior of these alluvial soils are presented. Alluvial soil is taken from Çiğli, Balatçık (Izmir, Turkey). To determine geotechnical index properties; wet sieve analysis, plastic limit, liquid limit, specific gravity, standard compaction tests were conducted. In order to determine the effect of fly ash on compaction behavior of alluvial deposits, three different samples (fine < 0.425mm, medium < 2mm, and coarse < 4.75 mm) are prepared and 10%, 15%, 20% fly ash by dry weight of soil is mixed and standard proctor test is performed. As a result of laboratory tests, the liquid limit, plastic limit, and plasticity index values obtained as 38.3%, 25.7%, and 12.6%, respectively. The specific gravities for fine, medium, and coarse samples are 2.68, 2.67, and 2.66, respectively. According to the results of wet sieve analysis and consistency limit tests, it was stated that the soil contains large amounts of sand and clay. The washed sieve analysis and consistency limit tests results were evaluated according to USCS. The conducted test results have shown that maximum dry unit weight for fine, medium, and coarse soils are 16.9, 19.35, and 19.55 (kN/m3), and optimum moisture content for fine, medium, and coarse samples are 17, 11, 10.5% respectively. Generally, by increasing the content of FA, maximum dry unit weight decreased and optimum moisture content increased for all three types of alluvial soil. By increasing FA to 20%, maximum dry unit weight of medium and coarse soils decreases 1.5% and 2%, respectively.

Abstract:
Изучение гранулометрического состава почв Ханкайского заповедника показало, что профили почв представляют собой многослойные спектры различного литологического сложения. Сложность почвенных профилей по гранулометрическому составу определяется степенью проявления поемного и аллювиального процессов, литологическими особенностями почвообразующего материала. По типу сложения выделено несколько литологических групп. Темно-гумусовые глеевые, аллювиальные луговые глеевые почвы и буроземы глееватые отличаются резкой дифференциацией профиля по гранулометрическому составу на верхнюю легкую и нижнюю глинистую толщу. Для этих почв отмечено наибольшее содержание фракций физической глины и ила по всему почвенному профилю. Буроземы типичные и аллювиальные луговые глееватые, вышедшие из зоны затопления, характеризуются литологически однородным легким составом. В этих почвах выявлено высокое содержание фракций мелкого песка. The soil profiles the Khankaiskiy Nature Reserve represent multilayer spectra of various lithological addition. The complexity of soil profiles in terms of particle-size distribution is determined by the degree of manifestation of soil and alluvial processes, lithological features of soil-forming material. Several lithological groups are distinguished by the type of texture. Dark humus gley, alluvial meadow gley soils and burozem gleyic shrouds are distinguished by a sharp differentiation of the profile by granulometric composition into an upper light and lower clay thickness. The largest content of fractions of physical clay and silt was noted throughout the profiles for these soils. Burozem typical and alluvial meadow gleyic soils that have emerged from the flood zone characterize this with a lithologically homogeneous light composition. A high content of fine sand fractions was revealed in these soils.

Abstract:
Based on the monitoring of changes in climate indicators of the dry-steppe zone of Western Transbaikalia over the past 40 years, it has been revealed that the amount of effective rainfall, starting from the second six-year cycle, is steadily decreasing with a simultaneous increase in the amount of ineffective rainfall. As a result, there is a lack of moisture in the root layer of the soil and a soil drought is formed.
