Physical characteristics affecting the infiltration of high intensity rainfall into a soil profile
flood variable source areas soil retention capacity soil moisture suction pressure
2015/3/10
Flooding caused by intensive precipitation has been in the centre of attention of both general public and scientists. From the flood risk management perspective, an integrated approach to catchment ma...
Effect of agricultural lands afforestation and tree species composition on the soil reaction, total organic carbon and nitrogen content in the uppermost mineral soil profile
acidification afforestation carbon nitrogen soil reaction
2015/3/10
Forests occupy one third of the world’s land area and govern carbon (C) transfers and influence nitrogen (N) content in the biosphere. Afforestation leads to soil changes of specific dynamics, often a...

different soil depths and period of cultivation on the distribution of weed seed bank in the soil profile ...
Comparison between field measurements and numerical simulation of steady-state solute transport in a heterogeneous soil profile
field measurements solute transport numerical simulation soil profile
2009/6/8
Field-scale solute dispersion is determined by water flow heterogeneity which results from spatial variability of soil hydraulic properties and soil moisture state. Measured variabilities of soil hyd...
Simulation of soil moisture and evapotranspiration in a soil profile during the 1999 MAP-Riviera Campaign
MAP-Riviera Project soil moisture evapotranspiration
2009/3/16
Detailed plot-scale observations of basic hydrometeorological variables represent valuable data for assessing the quality of the soil moisture module and evapotranspiration scheme in hydrological mode...
A joint inversion of apparent resistivity and peak-period of microtremor horizontal-to-vertical spectrum for shallow soil profile
microtremors horizontal-to-vertical spectrum S-wave velocity vertical electrical sounding resistivity simulated annealing
2009/3/5
We propose a new technique for a joint inversion of apparent resistivity data from a vertical electrical sounding and peak-period of spectral ratio of horizontal microtremors to vertical one in order ...
Effects of Wheel Traffic Porosity and Compaction of Soil Profile
Wheel Traffic Porosity Compaction Soil Profile
2009/1/14
The aim of this experimental study was to determine the effect on soil porosity and compaction of the number of the tractor passes on the soil surface. The soil has a sandy loam texture. A tractor pas...
The Effect of Soil Profile Depth on Fallow Efficiency Under Ankara Conditions
Fallow efficiency profile depth nitrogen fertilization
2009/1/14
The aim of this study was to compare the fallow efficiencies of shallow and deep soil profiles and to examine the effects of nitrogen fertilization on the grain yields in continuous wheat and fallow-w...
Formation of Trioctahedral Illite from Biotite in a Soil Profile Over Granite Gneiss
Biotite Electron microprobe Illite Mica Scanning electron microscopy Trioctahedral Weathering X-ray powder diffraction
2012/1/4
Clay fractions separated from the A2, B, and C horizons of a soil formed on granite gneiss showed X-ray powder diffraction (XRD) spacings characteristic of trioctahedral illite. The trioctahedral illi...
