The soil had eight perfect fine particles with the liquid limit, plastic limit and the index of plasticity being 49, 29, and 20, respectively. Therefore, according to the Unified Soil Classification System, fine particles are classified as silt with low plasticity, and the overall classification ...
Soils are classified as Gypsiric Leptosols (IUSS Working Group WRB, 2006), have pH values ~7 and 1–12% of inorganic C (as carbonates). The site has a plant cover of <40% (dominated by Stipa tenacissima), and the open areas between plant patches contain well-developed biocrust ...
Soil is a natural aggregate of mineral particles. Soils are classified into coarse-grained and fine-grained soils. Majority of the coarse-grained soils suit for the construction activities. Problems pose to the structures raised in/on or with fine-grained soils and few coarse-grained soils due ...
In sandy soils, sand particles are retained by bonding between particles and the force can be transmitted through these joints. During lubrication, these joints break down and the force between them becomes cavity pressure and the soil shear strength becomes zero. Sandy soil behaves like a liquid...
The soils are classified as Cambisols (Bo, Hl, Vr), Chernozem (Ha) and Podzol (Me) according to the World Reference Base for Soil Resources (IUSS Working Group WRB, 2015). The site characteristics are given in Table 1. The plots were located at least 10 m away from the edges of ...
There are three main classifications of rock, based on the way the rock was formed: sedimentary, metamorphic and igneous. Soil is formed of fine rock particles mixed with air, water and particles from dead plant and animal matter. There are three main types of soil which are classified ...
What are the three types of soil texture? Soil Texture The particles that make up soil are categorized into three groups by size –sand, silt, and clay. Sand particles are the largest and clay particles the smallest. Most soils are a combination of the three. The relative percentages of sa...
Soil erosion is a natural geological phenomenon resulting from the removal of soil particles by water or wind (Gitas et al.2009). This natural process can be accelerated by human activities creating soil loss that exceeds the soil formation rate in a given area. Human activities that change la...

The outputs of this model is based on parameters such as average annual temperature, average slope of the study area, and drainage density etc. T, H, F and Z are classified as very high-sensitivity parameter while ϕ, Iav, X and Y may have medium to high sensitivity. Status...
