Comparison of the approaches to assessing the compressibility of the pore space
Записки Горного института, 2022 Integral and differential approaches to determining the volumetric compression of rocks caused by changes in the stress state are considered. Changes in the volume of the pore space of rocks are analyzed with an increase in its all-round compression ...

Tensor compaction of porous rocks: theory and experimental verification
Записки Горного института, 2022 Compaction in sedimentary basins has been traditionally regarded as a one-dimensional process that ignores inelastic deformation in directions orthogonal to the active load.

Modelling urban floods using a finite element staggered scheme with an anisotropic dual porosity model [PDF]
, 2019 In porosity models for urban flooding, artificial porosity is used as a statistical descriptor of the urban medium. Buildings are treated as subgrid-scale features and, even with the use of relatively coarse grids, their effects on the flow are accounted

The Assessment of Level of Flash Floods Threat of Urbanised Areas
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2017 Flash floods (or torrential rain flooding) is another type of flood hazard which has caused casualties and significant property damages. A methodology for identification of urban areas, which can potentially be burdened by that type of flood hazard, was ...
