Modeling radiocarbon dynamics in soils: SOILR version 1.1
soils Modeling radiocarbon dynamics
2014/12/19
Radiocarbon is an important tracer of the global
carbon cycle that helps to understand carbon dynamics in
soils. It is useful to estimate rates of organic matter cycling as
well as the mean residen...
Estimating soil organic carbon stocks of Swiss forest soils by robust external-drift kriging
Swiss forest soils robust external-drift kriging
2014/12/18
Accurate estimates of soil organic carbon (SOC)
stocks are required to quantify carbon sources and sinks
caused by land use change at national scale.
High-resolution hydraulic parameter maps for surface soils in tropical South America
tropical South America maps
2014/12/18
Modern land surface model simulations capture
soil profile water movement through the use of soil hydraulics sub-models, but good hydraulic parameterisations
are often lacking, especially in t...
Sensitivity analysis and calibration of a soil carbon model (SoilGen2) in two contrasting loess forest soils
Sensitivity analysis calibration soil carbon model two contrasting loess forest soils
2014/12/17
To accurately estimate past terrestrial carbon pools is the key to understanding the global carbon cycle and its relationship with the climate system. SoilGen2 is a useful tool to obtain aspects of so...
Variations of Natural Soil Salinity in an Arid Environment Using Underground Watertable Effects on Salinization of Soils in Irrigated Perimeters in South Tunisia
Oasis Irrigation Water Superficial Water Table Salinity Drainage Tunisia
2013/3/11
In arid and semi-arid regions, salinity is a serious and chronic problem for agriculture. The aim of this study is to evaluate the hydromorphical and salinity risks, and to evaluate the relationship a...
Interaction Properties of Geosynthetic with Different Backfill Soils
Geosynthetic Toyoura Sand Direct Shear Test
2013/3/11
Characterization of a geosynthetic is necessary for its effective use in various field application of reinforced soil structure. In this paper, a new type of geosynthetic has been evaluated for its in...

Concentrations of dissolved organic matter (DOM), dissolved humic substances (DHS), and DOM-complexed Fe (DOM-Fe) in Yamakuni and Oita Rivers, Japan, of which headstream is near in location, flow pass...
Geotechnical Properties of Problematic Soils Emphasis on Collapsible Cases
Soil Collapse South Rudasht Dorcheh Sivand
2013/3/7
Soils are unconsolidated materials that are result of weathering and erosion process of rocks. When water content of some soils change, it makes problems to civil activities. These problems include sw...
Evaluation of Quality of Some Rehabilitated Mined Soils within the AngloGold-Ashanti Concession in Ghana
Aggregate Stability Mean Weight Diameter Mined Soils
2013/3/7
Land degradation caused by surface mining of gold has been extensive in Ghana. In recent years rehabilitation of some degraded lands by re-vegetation has been undertaken. This study provides quantitat...
A Statistical Model for the Relative Hydraulic Conductivity of Water Phase in Unsaturated Soils
Unsaturated Soils Permeability Function Relative Permeability of Unsaturated Soils
2013/3/7
Permeability coefficients of fluids occupying the pore space of a porous medium have significant influence on the flow of these fluids through the porous medium. In the case of unsaturated soils, in a...
