There is an increasing awareness on the major benefits of using soil-geosynthetic composite (SGC) to achieve and maintain stability earth-filled embankment. Unlike mechanically stabilized earth wall, mechanism mass still not fully understood. For examples, current analyses have been limited SGC with a reinforcement spacing Sv 0.2 m only; combined effect backfill properties rarely studied; equat...

During construction works, it is advisable to prevent strong thawing and an increase in the moisture content of foundations engineering structures summer. Since density water ice differ, due difference bulging foundation sections can occur when freezes back winter. In this work, effect fiber-reinforced piles on thermal field surrounding soil investigated numerically; that is, study influence ag...

• Sentinel-2 composites for large scale mapping of soil organic carbon in croplands. Identification pure pixels and quantification uncertainty. Normalized Burn Ratio < 0.05 removes crop residues moisture. Soil property improves when more than 6 scenes per pixel are used composite. Uncertainty reaches 5.5 g C kg –1. (SOC) prediction from remote sensing is often hindered by disturbing factors at ...

Background and purpose: Nowadays, Presence of heavy metals such as cadmium in agricultural soils, is regarded as a serious threat to human health in recent years. Phytoremediation is a method by which heavy metal accumulate in plant tissues, hence elimination of these elements from contaminated soils would be possible. The aim of this study was to investigate the removal of cadmium from soil-co...
