Hydrocarbon Penetration in Multi-Porosity Soil

IOP Conference Series: Earth and Environmental Science, 2020
AbstractGroundwater contamination is crucial, particularly due to hydrocarbon liquid leakages. Additionally, the vibration impact affects the migration of hydrocarbon through the subsurface soil to the groundwater surface which is causes by the dynamic stress that is imposed on the soils. Therefore, this paper presents the investigation and discussions

Analysis of surface roughness in relation to soil loss and runoff at high rainfall intensities. [PDF]

, 2002
The decay of roughness is an important factor governing surface processes such as infiltration and soil erosion. Thus the decay of surface roughness under different surface conditions was investigated and related to quantitative amounts of soil loss ...

THE VOLUME AND POROSITY OF SOIL CRUMBS

Journal of Soil Science, 1966
Summary A simple and inexpensive apparatus (a test‐tube, burette, and pin) is described for measuring volumes by liquid displacement to an accuracy of greater than 0.5 per cent. This has been adapted to measure soil crumb porosities, ε c

Pedotransfer functions for soil organic carbon stock and soil porosity interpretation in diverse palm oil plantation soils

Sains Tanah: Journal of Soil Science and Agroclimatology
The accurate estimation of soil organic carbon stocks (SOCs) is crucial in sustainable oil palm plantation management. Pedotransfer functions (PTFs) serve as an essential predictive tool for enhancing the interpretation and estimation of soil organic ...

Influence of Coupling Effects between Gravel Soil Porosity and Cement Grout Weight on Diffusion Laws and Morphologies of Penetration Grouting

Applied Sciences, 2022
The practice and theory of grouting engineering show that both injected medium porosity and grouting fluid weight play an important influence on the diffusion law and morphology of penetration grouting.

Influence of absolute soil humidity on the porosity of soil packing

Traktory i sel hozmashiny, 2012
The influence of absolute soil humidity on the porosity of soil packing is shown. It is noted that soil porosity will be reduced at the expense of decreasing of air pores and increasing of solid particles volume as a result of soil compression with mover, strake, block etc. at constant humidity. The analysis of obtained models is given.
