Estimation of Soil Permeability using Soil Index Properties
Permeability is a very important engineering property of soils and finds utility in a number of soil engineering problems such as yield of wells and seepage through and below the earth structures. It controls the hydraulic stability of soil masses. The permeability of soils is also required in the design of filters required to prevent piping in hydraulic structures. However, the determination o...
متن کاملStudy of Air Relative Permeability Evolution during Soils Decontamination by Soil Vapour Extraction
Soil vapour extraction (SVE), is the primary method used in the world to remove volatile organic compounds (VOCs) from unsaturated subsurface porous media. The objective of this work is to study the change of the soil air relative permeability during continuous venting and removal of contaminant from a polluted soil. Once the flow starts, the contaminants will volatilize and the volume of liqui...
متن کاملSoil invertebrates as bioindicators of urban soil quality.
This study aimed at relating the abundance and diversity of invertebrate communities of urban soils to chemical and physical soil characteristics and to identify the taxa most sensitive or tolerant to soil stressors. The invertebrate community of five urban soils in Naples, Italy, was sampled. To assess soil quality invertebrate community indices (Shannon, Simpson, Menhinick and Pielou indices)...
متن کاملFostering soil stewardship through soil quality assessment
Soil quality is not a purchased technology; instead, it is a concept that can be used in making land management decisions. Researchers have generally agreed upon the soil properties that determine soils’ capacity to function and have emphasized that soil quality must be understood in context. Soil quality research has included the following: (1) soil management research, where the effects of ma...
