A susceptibility assessment system was developed in 2008. The Joint Technical Committee on Landslides and Engineered Slopes (JTC-1) combined the work of the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE), the International Society for Rock Mechanics (ISRM), and the Inte...
The freeze–thaw process of active layer can alter soil hydrothermal dynamics and plays an important role in the stability of permafrost ecosystem, particularly under the background of permafrost degradation resulting from climate warming. Wetlands in permafrost regions are considered to be symbiotic with...
The pulsed events of rainstorm erosion on the Loess Plateau are well-known, but little information is available concerning the characteristics of superficial soil erosion processes caused by heavy rainstorms at the watershed scale. This study statistically evaluated characteristics of pulsed runoff-erosion...
One of the Employers Requirements states land drainage within jet engine blast and jet ingestion areas shall be buried beneath top soil. The top soil is highly impermeable so they system would collect properly the storm water from the surface. I have seen you have been working in London ...
Engineering mechanical properties of six typical hazardous waste samples were investigated. The results show that the water contents and organic matter contents of sludge-class hazardous waste are much higher than that of non-sludge-class hazardous wastes, but the specific gravity of the former is ...
Thus, 1) the use of agricultural assets such as fertilizers, pesticides, and films, and agricultural machinery inevitably results in carbon emissions. 2) When irrigation is directly or indirectly conducted, residual pollutants in the soil deteriorate its original physical and chemical properties, ...
Therefore, in most arid regions, the upper limit of the ecological water level range is defined as the level causing intense evaporation of groundwater, leading to soil salinization. The lower limit is the water level at which plant roots cannot reach the aquifer, leading to ecological ...
where Sr is the degree of saturation, w is the gravimetric water content, e is void ratio (assumed constant, further explained), Gs is the specific gravity of soil solids, s is total suction, P and λ are constants and Sr,max and Sr,res are, respectively, the maximum and residual degr...
Based on our field investigations of landslide hazards in the Wenchuan earthquake, some findings can be reported: (1) the multi-aspect terrain facing empty isolated mountains and thin ridges reacted intensely to the earthquake and was seriously damaged;
The measurement time was about 2 s, giving an accuracy of 1 × 10−7 m3/kg (SI unit). • Grain size: The pretreatment process of soil particle composition comprised of three steps. First, 10% hydrogen peroxide (H2O2) was added to remove soil organic matter, then, 10% hydrochloric ...
