TL;DR: A review of the full-scale and developing technologies that are available for metal removal can be found in this paper, where the main techniques that have been used for removal of metals from contaminated soils and sediments are discussed.

TL;DR: In this paper, the authors provide an overview of the laboratory research, field demonstration and full-scale application of surfactants for the remediation of contaminated soil and discuss three types of biosurfactants evaluated for their effectiveness They included a lipopeptide called surfactin from Bacillus subtilis, a rhamnolipid from Pseudomonas aeruginosa and a sophorolipids from Torulopsis bombicola.

TL;DR: In this paper, an integrated multi-disciplinary approach was performed to achieve a clear comprehension of the gravity deformation in the deep-seated slope deformation (DSGSD) in the Rhaetian Alps.

TL;DR: In this paper, a GIS-aid to the geo-environmental evaluation for urban land-use planning is illustrated for the urban area of Lanzhou City and its vicinity in Northwest China.

TL;DR: In this paper, the authors investigated two aspects of critical importance to landslide hazard and risk assessment and management: magnitude-cumulative frequency relationship for landslides, and relationship between rainfall and the occurrence of landslides.

TL;DR: In this article, the authors present results of deformation experiments focusing on the transport properties of rock salt and describe the conditions for the transition from non-dilatant to dilatant deformation at the so-called dilatancy boundary.

TL;DR: In this paper, the authors used electrical resistivity method to delineate zones favorable for seepage, whereas, self-potential (SP) method was used to determine the path of seepages.

TL;DR: In this article, the behavior of unsaturated clayey soil is highly influenced by the coupled interaction between water and clay content, and the effect of clay content on hydraulic conductivity and swelling potential.

TL;DR: In this article, the authors highlight the fundamental flaws of the current landfill leachate containment strategy and highlight the need to consider the local geological/hydrogeological conditions during selection of landfill sites.

TL;DR: In this paper, a mass of Quaternary pyroclastic rock (est. vol. 0.74×106m3) slides from the western flank of the Cayley volcano in southwest British Columbia and forms a rock avalanche that travels a horizontal distance of 3.46 km from its source over a vertical elevation difference of 1.18 km.

TL;DR: In this article, the shrinkage and desiccation cracking exhibited by bentonite-enhanced sand mixtures (BES) upon air-drying were investigated. But the results were limited to the case of BES containing 10 and 20% bentonite.

TL;DR: In this article, an experimental salt weathering simulation and porous stone durability classification are proposed, which is a comparable study of weight loss and degradation of visual appearance due to salt crystallisation using, on the one hand, a standard durability test (UNE), and, in the other, the proposed durability test is comparable to the degradation of building stone.

TL;DR: In this paper, a probabilistic analysis of rock wedge failures is proposed, where probability of kinematic instability and probability of kinetic instability are evaluated separately to provide a proper, combined evaluation for failure probability.

TL;DR: In this article, the influence of cyclic wetting and drying on the swelling behaviour of wood-ash-modified BCS and laboratory lime-treated BCS specimens are examined in a study required to assess the long-term behaviour of chemically stabilized soils in geotechnical applications.

TL;DR: In this paper, the authors investigated and statistic analyzed the landslide hazards in the forereservoir region of the Three Gorges Project on the Yangtze River, the major factors that are found to have affected the slope stabilities are outlined, and a zonation of landslide hazards of the region is made using an integrated information model.

TL;DR: In this paper, the authors measured site resonance periods throughout metropolitan Memphis, Tennessee and estimated the average shear wave speed of unconsolidated sediments as a function of sediment thicknesses.

TL;DR: In this paper, the authors studied the development process and formation of slip surfaces and clays in landslides in Japanese Tertiary volcanic rocks in order to determine the causes of repeated movement of Japanese landslides.

TL;DR: In this paper, a series of coupled solute and moisture leaching column tests, using different heavy metal solutions, were conducted on an unsaturated illitic soil at varying pH values.

TL;DR: In this paper, the authors examined the potential of pozzolanic fly ash as a hydraulic barrier in land fill and showed that fly ashes possess low shrinkage and hence do not crack.

TL;DR: The cataclinal overdip slope accelerates creep movement of micro-sheeted granite, which in turn loosens and disintegrates granite via widening or neoformation of cracks, probably in combination with stress release, temperature change, and changes in water content near the ground surface.

TL;DR: In this article, an interpretation model was developed by the authors to obtain the uniaxial compressive strength of porous materials from the results of indentation tests, based on the model proposed by Wilson et al. (Int. J. Mech. Sci., 17, 1975, 457) for the interpretation of indentation tests on compressible foams and on an estimation of the extent of the compacted zone under the indenter.

TL;DR: In this article, a non-reflector total station is used to measure the orientation of a set of points on the exposed fracture surface at a distance from the rock face, and the best-fit plane is defined by the co-ordinates of the target points and the orientation (e.g. dip angle and dip direction) of the fracture surface is determined as that of its best fit plane.

TL;DR: In this article, a consensus logic tree of possible alternative parameters was developed for the New Madrid seismic zone and a variability analysis was performed using Monte Carlo sampling of this logic tree for 2-exceedence-in-50-year hazard.

TL;DR: In this article, the authors used the Subsidence With Influence Function Technique (SWIFT) to predict the likelihood and magnitude of mining subsidence in the British Coal Corporation and the University of Nottingham.

TL;DR: In this paper, a simplified performance-based method for evaluating landfill bottom liners is presented, which is based on results from 3D analyses that have been conducted for a variety of cases.

TL;DR: In this paper, a typical residual soil sample from the lateral scarp of the La Orotava amphitheatre on Tenerife was analyzed using environmental scanning electron microscopy and a particular bonding was detected by geotechnical tests.

TL;DR: In the last 40 years, a part of the Thessaloniki coastal plain, a delta formed in the last 2500 yr, subsided at a rate of up to 10 cm/yr as discussed by the authors.

TL;DR: In this article, the chemical characteristics of leachates and leached solid samples from a study into the long-term durability of a lime strengthened silt/pfa mixture amended with sewage sludge were investigated.
