Stabilization of organic matter in soil is important for natural ecosystem to sequestrate carbon and mitigate greenhouse gas emission. It is largely unknown what factors govern the preservation of organic carbon in soil, casting shadow on predicting the response of soil to climate change. Iron oxide was suggested as an important mineral preserving soil organic carbon. However, ferric minerals a...

Soil and water resources management of rivers has an important role because of direct relation withdifferent systems such as earth, life, social and people. Although the use of vegetation cover inbioengineering and biological stabilization and also soil and water resources management projects hasmany advantages, but improper methods of design and implementation cause hydraulic specificationsof ...

Stabilization/Solidification technologies reduce the mobility of hazardous and radioactive contaminants in the environment through both physical and chemical processes. Four stabilization/solidification (S/S) processes were used to solidify three sample matrices contaminated with arsenic, chromium (VI), lead, cesium and strontium. These sample matrices were Idaho National Engineering and Enviro...

Risk-based slope stabilization planning integrates the failure probability and the failure consequence systematically and shows promise for use in the practice. This paper attempts to develop a risk-based methodology for stabilization planning for deteriorating soil cut slopes. First, a framework of risk-based stabilization planning for slopes is proposed. Then the time-dependent reliability of...

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract Over the past few decades Road infrastructure in India is developing at a quick pace. A decent pavement is required for the safe, comfortable and prudent development of traffic. The thickness of road relies on geotechnical properties of subgrade so...

Iraq is one of the biggest countries in oil production and its processes. Bitumen a by-product material that remains after process crude oil. This study designed to investigate role bitumen stabilization lead contaminated Iraqi soil; as measured by newly developed “mini” Jet Device dispersion ratio method (DR,%).
 The results revealed both amount mixing with soil, direct or emulsion mixing...

Extreme sensitivity of soil organic carbon (SOC) to climate and land use change warrants further research in different terrestrial ecosystems. The aim of this study was to investigate the link between aggregate and SOC dynamics in a chronosequence of three different land uses of a south Chilean Andisol: a second growth Nothofagus obliqua forest (SGFOR), a grassland (GRASS) and a Pinus radiata p...
