Abstract:
Fickian and non-Fickian behaviors were often detected for contaminant transport activity owed to the preferential flow and heterogeneity of soil media. Therefore, using diverse methods to measure such composite solute transport in soil media has become an important research topic for solute transport modeling in soil media. In this article, the continuous-time random walk (CTRW) model was applied to illustrate the relative concentration of transport in low-permeability homogeneous and saturated soil media. The solute transport development was also demonstrated with the convection-dispersion equation (CDE) and Two Region Model (TRM) for comparison. CXTFIT 2.1 software was used for CDE and TRM, and CTRW Matlab Toolbox v.3.1 for the CTRW simulation of the breakthrough curve. It was found that higher values of determination coefficient (R2) and lower values of root mean square error (RMSE) concerning the best fits of CDE, TRM, and CTRW. It was found that in the comparison of CDE, TRM, and CTRW, we tend to use CTRW to describe the transport behavior well because there are prevailing Fickian and non-Fickian transport. The CTRW gives better fitting results to the breakthrough curves (BTCs) when β has an increasing pattern towards 2.00. In this study, the variation of parameters in three methods was investigated and results showed that the CTRW modeling approach is more effective to determine non-reactive contaminants concentration in low-permeability soil media at small depths.

Abstract:
This paper compared the abilities of advection-dispersion equation (ADE) and spatial fractional advection-dispersion equation (sFADE) to describe the migration of a non-reactive contaminant in homogeneous and heterogeneous soils. To this end, laboratory tests were conducted in a sandbox sizing 2.5 × 0.1 × 0.6 m (length × width × height). After performing a parametric sensitivity analysis, parameters of sFADE and ADE were individually estimated using the inverse problem method at each distance. The dependency of estimated parameters on distance was examined. The estimated parameters at 30 cm were used to predict breakthrough curves (BTCs) at subsequent distances. The results of sensitivity analysis indicated that average pore-water velocity and dispersion coefficient were, respectively, the most and least sensitive parameters in both mathematical models. The values of fractional differentiation orders (α) for sFADE were smaller than 2 in both soils. The scale-dependency of the dispersion coefficients of ADE and sFADE was observed in both soils. However, the application of sFADE to describe solute transport reduced the scale effect on the dispersion coefficient, especially in the heterogeneous soil. For the homogeneous soil, the predicting results of ADE and sFADE were nearly similar, while for the heterogeneous soil, the predicting results of sFADE were more satisfactory in comparison with those of ADE, especially when the transport distance increased. Compared to ADE, the sFADE simulated somewhat better the tailing parts of BTCs and showed the earlier arrival of tracer. Overall, the solute transport, especially in the heterogeneous soil, was non-Fickian and the sFADE somewhat better described non-Fickian transport.

Abstract:
Designing an effective grounding system for AC substations needs predetermination of ground resistance and ground potential distribution caused by fault current’s presence in the ground. Therefore, it is necessary to have a suitable grounding grid structure in the soil properties in which the grid is buried. Though the soil composition where the grounding grid is located is typically non-homogeneous, the soil is often presumed to be homogeneous due to the complexities of grounding system analysis in non-homogeneous soil. This assumption will lead to inaccuracies in the computation of ground resistance and ground potentials. Although extensive research has been done on non-homogeneous soil structure, comprehensive literature on grounding system performance in non-homogeneous soil is yet to be reviewed. Thus, this paper reviews the effect of non-homogeneous soil on the grounding system, with different soil characteristics in horizontal and vertical two-layer soil structure and the horizontal three-layer soil structure. In addition, the effect of design parameters on the grounding performance in non-homogeneous soil conditions for non-transient fault conditions is also studied. The significance of this study is that it provides a comprehensive review of grounding performance as grounding design changes and their effects as soil layers and their corresponding features change. This knowledge will be useful in developing safe grounding designs in non-homogeneous soil.

Abstract:
In this research, the program SEEP / W was used to compute the value of seepage through the homogenous and non-homogeneous earth dam with known dimensions. The results show that the relationship between the seepage and water height in upstream of the dam to its length for saturated soil was nonlinear when the dam is homogenous. For the non-homogeneous dam, the relationship was linear and the amount of seepage increase with the height of water in upstream to its length. Also the quantity of seepage was calculated using the method of (Fredlund and Xing, 1994) and (Van Genuchten, 1980) when the soil is saturated – unsaturated, the results referred to that the higher value of seepage when the soil is saturated and the lowest value of seepage when using Van Genuchten method for both homogeneous and non-homogeneous earth fill dams. Also relationship for the seepage (Q) with the curve fitting parameter (a) for sand, silt and clay soil was nonlinear when the dam is homogenous with constant variables (n, m) and the amount of seepage increase with increasing value of (a). The amount of seepage for a nonhomogeneous dam with a different value of (Kshell to Kcore) was calculated and then compared with the value of (K equivalent) which was equal to average (Kshell and Kcore) for the homogenous dam. The results show that when the average between (Kshell and Kcore) is ≤ 100 the difference was small between the quantity of the seepage calculated. For simplicity of the solution process, it can be replaced non-homogeneous dam by a homogenous dam with (K eq) when the values of Kshell and Kcore are less than or equal to 100.

Abstract:
A free water surface finite element model was developed. The method was implemented with the Galerkin approach to solve the Laplace equation in the saturated region. It was developed in the object oriented Visual C ++ computer language to permit easy update and drawing of the adaptive mesh. For each time step, the new water table position was calculated based on flux across the water table, a Brooks-Corey equation mass balance for the unsaturated region, and an equation that calculates water table position for the saturated region. An equation was developed to calculate a drainage transfer coefficient, alpha, based on percentage of perforated area in the drain tube wall. The drainage transfer coefficient was incorporated into the finite element model as a Fourier boundary condition. To validate the finite element model, its results were compared with the Kirkham equation results for steady state recharge of three subsurface drainage systems. The finite element model was used to calibrate a semi-analytical frozen stream tube model for subsurface drainage of heterogeneous soils. The first step in the calibration procedure is to run the finite element model for steady state recharge and calculate the water table height divided by recharge rate (the stream tube resistance to flow) as a function of distance between drains. Least squares regression is used to fit a polynomial logarithmic equation, called the resistance function, to the stream tube resistance to flow vs. distance from the drain curve. A differential equation based on the principle of conservation of mass and application of Darcy's law to the frozen stream tube was solved to obtain an equation that calculates stream tube flow rate and final water table elevation as a function of the resistance function and initial water table elevation. An example was developed for a non-homogeneous subsurface drainage system to illustrate the use of the semi-analytical model to predict water table fall and discharge.

Abstract:
Modelos de simulação de culturas são ferramentas usuais na literatura científica para representar o desempenho de uma cultura agrícola. Por representar os processos biofísicos, contém equações matemáticas e por operar em escala local, demandam investimento em equipamento e tempo computacional relativamente grande para sua execução. Ademais, nem sempre é possível obter dados climáticos e de solos cobrindo todo território brasileiro. Uma forma de representar regiões em escalas maiores é através da extrapolação das zonas edafoclimáticas homogêneas (ZEH). Portanto, objetivou-se no presente trabalho definir ZEH para as principais regiões de cana-de-açúcar do Brasil com base em dados de clima e de solo através de técnicas de geoestatística em um sistema de informação geográfica, afim de limitar ao máximo o número de pontos de simulação, sem prejudicar a representação espacial. Foram utilizadas 2.018 estações tanto meteorológicas quanto pluviométricas, além de 1.984 pontos de análises de perfis de solos espalhadas pelas principais regiões de cana-de-açúcar do Brasil. Os mapas das zonas climáticas e edáficas foram realizados através de técnicas de geoestatística e análises de indicadores estatísticos das variáveis espacializadas (VE). As escolhas das VE foram baseadas na literatura sobre zoneamento em escala global, dos quais foram selecionados para o presente trabalho, referente ao aspecto climático: graus-dias de crescimento (representando as condições térmicas do ambiente) e índice de evapotranspiração relativa (representando as condições hídricas no ambiente); referente ao aspecto edáfico, capacidade de troca de cátions (representando as características químicas) e água disponível no solo (representando as características físico-hídricas dos solos). Os mapas foram trabalhados em uma resolução de 10 quilômetros x 10 quilômetros. Numa primeira abordagem, obteve-se nove classes de zonas climáticas homogêneas e resultaram em dez classes de zonas edáficas homogêneas, totalizando 50 ZEH nas principais regiões canavieiras do Brasil, oriundas da combinação entre as classes de solo e clima. Uma segunda abordagem foi utilizada no sentido de se reduzir o número de classes finais, obtendo-se cinco classes de clima, oito classes de solo, o que resultou em 21 classes de ZEH ao final.<br>Crop simulation models are useful tools in the scientific literature to represent the performance of a crop in a given field. Because they are process-based and contain a number of algorithms and operate on a local scale, these models require investments in hardware and are usually time consuming. Furthermore, sometimes it is not possible to obtain climate and soil data covering the whole country. One way to represent regions at larger scales is by upscaling on homogeneous edaphoclimatic zones (HEZ). Therefore, the goal of the present study is define HEZ to the main sugarcane regions in Brazil based on weather and soil data through geostatistical techniques in a geographic information system, in order to limit number simulation points without harming the spatial representation. 2,018 weather stations in addition to 1,984 points of soil profile analyzes spread in the main sugarcane regions in Brazil were used. The maps of climate and edaphic zones were made through geostatistical techniques and statistical indicators analysis of spatialized variables (SV). The SV selected were based on homogeneous zone methods performed in global scale, from which were selected for climatic zones, thermal conditions (degree-days growth) and water conditions (relative evapotranspiration index); and edaphic zones, conditions chemical (cation exchange capacity) and water conditions (available soil water). The maps were made at a resolution of 10 km x 10 km. In the first approach, homogeneous climate zones resulted in nine classes and homogeneous edaphic zones resulted in ten classes, totaling 50 HEZ in the main sugarcane regions of Brazil, derived from the combination of the soil and climate classes. In a second approach were used in order to reduce the number of final classes, obtaining in climatic zones five classes, and in edaphic zones eight classes, in which resulted in 21 HEZ classes.

Abstract:
A infiltração é o processo pelo qual a água atravessa a superfície do solo, com grande importância para a hidrologia, irrigação e agricultura. À medida que a água infiltra, as camadas superiores do solo vão se umedecendo, alterando gradativamente o perfil de umidade. Sob condições de campo, a água que infiltra pode fluir tanto na vertical, como na horizontal, dependendo do tipo de solo e declividade do terreno. A taxa de infiltração da água no solo é afetada, principalmente, pelas características do solo que afetam a geometria de seu sistema poroso, como textura e estrutura, e pode ser determinada tanto no campo como em laboratório, por diferentes métodos. Com a intenção de otimizar a previsão da infiltração da água no solo, diversos modelos foram desenvolvidos, podendo ser classificados em três grupos: empíricos, semi-empíricos e com base física. O objetivo deste trabalho foi avaliar a infiltração de água em solos com diferentes texturas e comparar a qualidade do ajuste de diferentes modelos usualmente empregados. As curvas da taxa de infiltração e da infiltração acumulada foram determinadas em laboratório utilizando amostras de solo homogeneamente acondicionadas em colunas e comparadas pelos seguintes modelos: Kostiakov, Horton, Green & Ampt, e Philip. Dentre os solos estudados, o solo 3 (textura franco arenosa) foi o que apresentou a maior taxa de infiltração e a maior VIB, provavelmente devido a menor proporção de argila e maior presença de macroporos, facilitando a infiltração da água no solo. Dos modelos analisados, o de Kostiakov, seguido pelo de Philip, foram os que apresentaram em média os melhores valores estimados da taxa de infiltração quando comparados com os valores medidos em laboratório. O gráfico do avanço da frente de molhamento com a raiz quadrada do tempo de infiltração (horizontal) ajustou-se perfeitamente ao modelo de Philip. No que respeita a infiltração vertical tal gráfico foi semelhante ao da horizontal (linha reta), mas com maior inclinação.<br>Infiltration is the process in which the water passes through the soil surface, being of great importance for hydrology, irrigation and agriculture. As the water infiltrates, the soil water content profile will changing and the infiltrated water can flow vertically or horizontally, depending on the soil type and land slope. The soil water infiltration rate is mainly affected by soil properties that affect its porous geometry, such as texture and structure, and can be determined in the field and in the laboratory, using different methods. In order to optimize the prediction of the soil water infiltration, many different models have been developed and may be classified into three groups: empirical, semi-empirical and physically based. The objective of this study was to evaluate the water infiltration in soils with different textures and compare the quality of fit of the different used models. The infiltration rate curves and the cumulative infiltration curves were determined in the laboratory using soil samples homogeneously packed in column and compared by the following models: Kostiakov, Horton, Green & Ampt and Philip. Among the studied soils, the soil 3 (sandy loam texture) presented the highest infiltration rate and the highest basic infiltration rate, probably due to lower clay content and larger quantity of macropores, facilitating the water infiltration into the soil. Among the tested models, Kostiakov, followed by Philip, presented, on average, the best estimated values of the infiltration rate compared to the values measured in the laboratory. The front of the advancing wetting graph of the square root of the infiltration time (horizontal) well set to Philip model. With respect to this vertical graph infiltration was similar to the horizontal (straight line) but more inclined.

Abstract:
O estudo do comportamento mecânico do complexo sistema advindo da interação entre solo/subestrutura/superestrutura é o tema do trabalho. Neste contexto, a representação do maciço é feita usando-se o método dos elementos de contorno (MEC) em abordagem 3D, de maneira que se possa simular o maciço com características mecânicas não-homogêneas, além de se considerar uma camada de apoio indeslocável a distâncias prescritas a priori e condição de aderência perfeita. A subestrutura também é representada via MEC tridimensional, a qual está imersa dentro deste meio heterogêneo. A infra e a superestrutura são modeladas empregando o método dos elementos finitos (MEF), com o uso de elementos estruturais reticulares e elementos laminares. São apresentados alguns exemplos em que se valida a formulação e outros que demonstram a potencialidade e a necessidade de se empregar a formulação para a melhor análise do complexo fenômeno em estudo. Por fim, demonstra-se a obrigatoriedade de se otimizar a formulação, empregando-se duas grandes ferramentas numéricas: o paralelismo e o emprego de um adequado método de resolução de sistemas esparsos.<br>The analysis of the soil-structure system interaction is a vast field of interest in the area of civil engineering. A realistic representation of its behaviour. Thus, in the present research, the soil is considered a non-homogeneous continuum supported by a rigid and adhesive interface and modelled by boundary element method via Kelvin solution in 3D space. The foundation is also modelled by this above-mentioned modelling technique. The raft foundation and the superstructure are represented by finite shell and 3D frame elements. In order to estimate the accuracy and the potentiality of the proposed numerical formulation, some examples are validated when compared to similar approaches, and others simulations are presented to stress the necessity of coupling the non-homogeneous soil-foundation-radier-superstructure system as a whole. Finally, to acquire numerical time efficiency, it is shown that it is imperative to apply parallel processing and sparse techniques for the solution of the final system.

Abstract:
This paper presents an analytical solution for the steady-periodic heat transfer for a typical slab-on-grade floor building foundation beneath non-homogeneous soil medium. The impact of the above-grade walls on ground-coupled heat transfer is accounted for in the presented solution. The Inter-zone Temperature Estimation Profile (ITPE) technique is utilized to obtain the 3-D solutions to determine soil temperature distributions and to estimate foundation heat loss/gain from slab-on-grade floors. The impact of the non-homogeneous soil properties on the transient foundation heat transfer is investigated for various slab configurations and soil thermal properties.

Abstract:
The traditional soil dynamic impedance models, recommended by the main international seismic design codes of the nuclear power plant (NPP), are only expressed by a single parallel connection system of spring and dashpot which can not reflect the dynamic stiffness varying with excitation frequencies, and also can not simulate the cases of non-homogeneous site conditions. With the recent development of soil-structure interaction (SSI) analysis, based on the damping-solvent extraction method (DSEM) and the lumped parameter models recommended by seismic design codes of ASCE4-98,RCCG which are all applicable to the homogeneous site and also massless foundation model and viscous-spring artificial boundary model of especially fit for the numerical simulation of non-homogeneous site, comparative study of both the direct method and sub-structure method is carried out in this paper. Finally, by taking the analysis of floor response spectra (FRS) for a certain CPR1000 reactor building as an example, comparative analyses of homogeneous and layered site conditions using various soil dynamic numerical models above-mentioned are performed. In addition, in order to validate the accuracy, the calculated results are compared to that of SASSI program. The results show that FRS in the horizontal direction are good agreement regardless for the homogeneous and layered site conditions, the shapes of FRS in the vertical direction change obviously in the homogeneous site condition. This paper provides some guidance and reference in the aspect of evaluation the seismic suitability for the site of nuclear power plant (NPP).

Abstract:
Continuous profiles from in-situ penetrometer tests are now identified as essential for site specific soil investigation as part of designing offshore structures in deep and ultradeep waters and in highly layered seabed conditions. This paper describes the results from large deformation FE (LDFE) analysis undertaken to provide insight into the behavior of cone penetrometer penetrating through single layer non-homogeneous clays and three-layer uniform soft-stiff-soft clays. For the smooth cone penetration in non-homogeneous clays, the soil strength non-homogeneity factor was shown to have insignificant effect on the cone bearing capacity factor. However, for the rough cone, the bearing capacity factor in non-homogeneous clay was about 10∼12% lower than that in uniform clay. Bearing capacity factors for smooth and rough cones were also similar for non-homogeneous clay. For cone penetration in stratified soft-stiff-soft clays, a minimum layer thickness of 20 diameters was required to mobilise the full resistance of the stiff layer. The corresponding soil flow mechanisms are also discussed linking directly to the profile of penetration resistance.

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.
