Laboratory study on the effects of hydraulic and granulometric parameters on the response of granular soil to internal erosion [PDF]
, 2019 Erosion is a major environmental problem to agricultural land as well as to civil engineering infrastructures. Rainwater infiltration into granular soils can lead to the migration of fine particles by suffusion.

Usage of infinitesimals in the Menger's Sponge model of porosity
, 2011 The present work concerns the calculation of the infinitesimal porosity by using the Menger's Sponge model. This computation is based on the grossone theory considering the pore volume estimation for the Menger's Sponge and afterwards the classical ...

Microstructural characterization of a Canadian oil sand [PDF]
, 2012 The microstructure of oil sand samples extracted at a depth of 75 m from the estuarine Middle McMurray formation (Alberta, Canada) has been investigated by using high resolution 3D X-Ray microtomography ($\mu$CT) and Cryo Scanning Electron Microscopy ...

Soil Strength and Porosities Associated with Cropping Sequences [PDF]
Soil Science Society of America Journal, 1974 Abstract The effects of cropping sequences on the strength and porosity of the Portneuf silt loam soil were studied in south‐central Idaho under normal field conditions. Undisturbed soil cores were collected from the surface 20 cm of seven fields with cropping histories ranging from continuous pasture to ...

Assessment of tillage systems in organic farming: influence of soil structure on microbial biomass. First results [PDF]
, 2007 Soil tillage modifies environmental conditions of soil microorganisms and their ability to release nitrogen. We compare the influence of reduced tillage (RT) and mouldboard ploughing (MP) on the soil microbial functioning in organic farming.

Acute Sensitivity of Landslide Rates to Initial Soil Porosity
Science, 2000 Some landslides move imperceptibly downslope, whereas others accelerate catastrophically. Experimental landslides triggered by rising pore water pressure moved at sharply contrasting rates due to small differences in initial porosity. Wet sandy soil with porosity of about 0.5 contracted during slope failure, partially liquefied, and accelerated within ...
