Abstract:
... Freeze–thaw (FT) cycles would alter physical and chemical properties of soil and thus influence the transport of plastic particles (one type of emerging contaminant with great concerns). This study was designed to investigate the effects of FT treatment on the mobility of plastic particles (nanoplastics as representative) in columns packed with natural soils (i.e. loamy sand and sandy soil, quartz ...
... This study investigated the respective correlation coefficients between pore water pressure (PWP) development in sandy soil and 41 CAV-based (cumulative absolute velocity) ground motion intensity measures and peak ground acceleration (PGA). Based on 720 site response analyses using DEEPSOIL with 120 (real) strong ground motions and the (real) borehole data (e.g., soil unit weight, shear-wave veloc ...
... The suitability of using time-domain reflectometry (TDR) for landslide monitoring and assessment has been validated by field studies. This method can be used for detecting shear surfaces and monitoring shear displacements at depth, which can provide warning of potential slope failures or landslide reactivations. Although laboratory tests have suggested using the TDR reflection coefficient to estim ...
sandysoils, etc ; catenas; detritus; granite; gully erosion; China; Show all 6 Subjects
Abstract:
... Recently, there has been an increase in collapsing gullies in the south of China as one of the most destructive types of soil erosion. Most collapsing gullies are formed on a well-developed granite crust; thus, granite residual soil plays a critical role. However, the extent to which the geotechnical features of residual soil, especially soil disintegration, affects collapsing gully formation is p ...

Abstract:
... Light non-aqueous phase liquids (LNAPLs) spilt over an area can be a persistent and long-term source of groundwater contamination. Once the groundwater gets contaminated, it is difficult to remediate. Migration of the spilt LNAPL should be contained within the unsaturated zone of the soil such that the LNAPL does not reach the groundwater source. Although the presence of LNAPLs in the unsaturated ...

Abstract:
... Accurate identification of sandy land plays an important role in sandy land prevention and control. It is difficult to identify the nature of sandy land due to vegetation covering the soil in the sandy area. Therefore, HJ-2A hyperspectral data and GF-3 Synthetic Aperture Radar (SAR) data were used as the main data sources in this article. The advantages of the spectral characteristics of a hypersp ...

Abstract:
... To contribute to the development of a novel cropping system for potato grown from greenhouse-derived seedlings from hybrid true potato seeds, planting density trials were carried out under normal Dutch agronomic conditions. For two consecutive years, 5-week-old seedlings of two experimental genotypes were transplanted into farmers’ potato production fields at two contrasting locations: a flat-bed ...

Abstract:
... The measurement of groundwater level and surface displacement in a sandy model slope under repeated rainfall was conducted to examine the effect of repeated pore pressure loading and unloading on the slope deformation. The velocity increased with small fluctuation even immediately before failure. Positive and negative accelerations occurred due to fluctuations in the velocity. The velocity increas ...

Abstract:
... Building highway and its biological protection system in a drought-affected shifting-sand desert is a great challenge. This challenge was completed by the construction of the Taklimakan Desert Highway Shelterbelt (TDHS)—the longest of its kind in the world (436 km). The TDHS can serve as a model for highway construction and desertification control using eco-friendly and cost-effective approaches i ...

Abstract:
... Calculating the velocity and migration of plant‐parasitic nematodes in soil is important for understanding individual roles in nematode populations. Tracking individual nematodes in the soil is difficult, and any marking system can alter the behavior of second‐stage juvenile (J2) nematodes. This study examined the velocity of Meloidogyne ethiopica J2s under different soil moisture conditions and p ...

Abstract:
... Accurate quantification of root structure is essential for understanding plant ecological system. Nevertheless, the lack of in-situ root characterization methods has limited further research of the relevant field. Heat pulse (HP) technique has emerged as a promising, cost-effective in situ monitoring approach. The existing HP technique relies on the analytical solution of heat transfer model with ...

Abstract:
... The objectives of this study were investigating the photodegradation of the polycyclic aromatic hydrocarbons (PAHs) in modified petroleum impregnated bentonite mulch through solar radiation, determining PAHs’ translocation in the soils that underlay the mulch and finding a solution to prevent the uncontrolled release of petroleum into the environment. For this research, various formulated mulches ...

Abstract:
... The expansion of agricultural frontiers has increased the use of sandy soils as cropping areas; however, the water‐retention capacity (WRC) of the soil is a crucial factor. Thus, fast and accurate methodologies, such as spectroscopy, have gained importance to identify physical‐hydric and other attributes related to the WRC. Some theories indicate the micromorphometry of particles is an important f ...

Abstract:
... Creosote is a complex mixture containing mainly polycyclic aromatic hydrocarbons (PAHs). The remediation of creosote-contaminated sites becomes a challenge due to the numerous compounds and the specific soil properties. Treatability tests using advanced homogeneous (HM system) and heterogeneous (HT system) oxidative processes were applied with sandy soil artificially contaminated with creosote. Th ...

Abstract:
... Cover crops can affect nitrogen fertilization efficiency, soil nitrogen content, and cotton yield. However, the interaction effects of controlled-release nitrogen fertilizers, applied N rate, and cover crops on cotton growth, yield and fiber quality remains unknown, especially in sandy soils with low N content. Soil nitrogen and cotton growth, yield and fiber quality were evaluated as a function o ...
