moringa pregerina (forssk.) fiori.,capparis decidua (forssk.) edgew. and salvadora oleides decne. are important indegenious shrub or tree species of sahara-sindian region which distributed and formed scattered woodlands in south east of iran. the current research was carried out to find most effective soil characteristics intheir distribiution. for this purpose, a study was conducted in the bal...

The objective of this paper is to analyze the behavior of specular scattering for different soil texture fields at various soil moisture (mv) and analyze the data to retrieve the soil moisture with minimizing the effect of the soil texture. To study the soil texture effect on specular scattering 10 different soil fields were prepared on the basis of change in soil constituents (i.e., percentage...

Characterization of soil corrosivity in archaeological sites is an important subject to understand the conservation conditions of archaeological bronze collections and helps conservators to prepare a conservation strategy for long term preservation of bronze objects. In this paper, a research approach is established to identify soil corrosivity in two archaeological sites and to find correlatio...

the purpose of the present research was to study the properties of natural habitats and growth status of the genus tamarix in miankangi, sistan province, south-eastern iran. selective sampling was used to examine the natural stands structure. then, the one ha-rectangular sample plots were stablished in the stands and surrounding bare lands as control plots. quantitative variables of stands viz....

sodic soil is one of the most common problems of limiting agricultural production that related on irrigation. saturated hydraulic conductivity is one of hydrodynamic characteristics in evaluating transmission flow through underground levels. to investigate the role of increment of exchangeable sodium in hydraulic conductivity changes (as characterized by the mobility of water in soil) an experi...

cation exchange capacity and specific surface area are among some of the important soil characteristics the direct measurement of which is laborious, costly and time consuming. therefore, fractal dimension of particle size distribution has been widely studied in relation with many such dynamic and static processes as transmission of water and solutes, water holding capacity, heat storage and co...

[1] In the past, texture-based classification of soils has been used for grouping soils in variably saturated water flow and solute transport studies. Classification of soils becomes especially important for large-scale studies where the spatial and temporal variability in the hydraulic properties of soils exceeds the field sampling capabilities. Although soiltexture-based classification has be...

This study employs a diverse set of variables to explain slope stabilization on stable versus failure-prone revegetated cut-slopes in Korea. A field survey was conducted at potential unstable sites and stable sites using 23 variables. Through a non-parametric test of the field survey results, 15 variables were identified as primary determinants of slope failure. Of these variables, one describe...
